Blow off valve kit

WRX/STi

XT/Baja Turbo

Unique design guarantee’s smooth running and reliable performance. The Dual Exit system routes roughly 50% of the air back to the Factory Recirculation pipe and 50% of the air out a Billet machined horn. In effect the valve is a Bypass and a Blow off valve in one unit. Available in Red, Black and Silver. Kit includes all parts to bolt directly to OE Intercooler as well as custom bolt up flange to fit return hose. Unique design allows both venting to atmosphere to give that unique "whoosh" noise as well as part venting back to inlet. Venting: Twin staged outlets, one plumb back, one atmosphere trumpet.

Agency Power Adj. Blow Off Valve Subaru WRX 08

With all turbocharged vehicles, keeping the turbo spooled up and boost pressure consistent is necessary for optimal performance. To enhance the new 2008 Subaru WRX, we have developed this fully adjustable and configurable blow off valve for your vehicle. The BOV body, flange, and adapters are CNC machined 6061 aluminum. Each component is anodized in your choice of blue, red, or silver. Internally, the valve uses a piston and spring design to hold the boost pressure. The steel coil spring has been tested to hold up to 40psi of pressure. The piston is made out of a durable brass which includes a Delrin washer to provide efficient movement inside the valve body. The valves top adjustment knob features a laser engraved AP logo, which can be turned to stiffen or loosen the spring. A locking collar is included which is made in stainless steel.

The valve can be set up in 3 configurations depending on your vehicles performance level and tuning. You can configure it as a 100% recirculation, 50/50 (where some recircs and some vents to atmosphere), and then 100% atmospheric where all the air is vented out. All appropriate plugs and fittings are included. The 50/50 setup is pictured. This valve fits all 2008 and up Subaru WRX GH and GE chassis with the factory top mount intercooler or intercooler flange.

Forge Recirc Blow Off Valve

02+ WRX/STi

Forester XT

Baja Turbo

Made from billet aluminum, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably. Unlike the Diaphragms valves this uses a single piston single spring to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.

In a car with a MAF sensor, when a BOV vents, air is escaping from a closed system. This air has already passed through the MAF sensor and has been measured, and the computer doesn't know that this air never made it to the engine. This will cause a brief rich mixture as the computer will still deliver the correct amount fuel dosage based on the amount of vented air. The resulting rich mixture is what can sometimes cause backfiring and a puff of smoke in some cars. The severity of these effects usually depend on the state of tune of the engine. But to be 100% safe requires the air to be 100% recirculated back into the system. This is where the Forge Recirc BOV shines, maximizing power between shifts while remaining safe for the car's system.

Forge valves include the valve spring tuning kit, this will allow you to configure the valve to its optimum set up.

Manual Boost Controller

WRX and STis have factory boost management that can vary boost level. Boost levels can vary based on gear, RPM, throttle position and more. With the simple installation of the PERRIN Performance™ boost controller you regain the ability to change and/or hold boost at whatever level you choose. This flexibility will increase low end boost response (in some cases as much as 750 RPM sooner than stock) in all gears and allow upper end increases in boost level. All will net a much faster vehicle without sacrifices to drivability.

The PERRIN Performance™ boost controller features a custom wound spring and ceramic metering ball for boost management. Months of testing with different spring rates and ball compositions allowed PERRIN™ to achieve the perfect balance of level and response. The lightweight ball and spring also prevent dangerous over-boosting found in other competitive units.

The PERRIN™ boost controller is easy to install and easy to adjust. Most shade-tree mechanics can install and be enjoying their new power in less than 30 minutes. Using indicator marks around the body of controller, the user can make adjustments in small or large increments (as fine a 1/4 lb!). Basic instructions, connectors, silicone hose and mounting hardware are all included with the controller. Some simple hand tools are all that's required to perform a professional installation.

AP Manual Boost Control Kit

AP brand new Manual Boost Controller is now available for your turbo charged vehicle. Designed with performance, fitment, and style in mind, the AP MBC will give your turbo vehicle some much need horsepower with a couple of easy twists of the unique adjustment knob not seen on any other manual boost controller.

How does the AP MBC work? Simple! The MBC is a bleed valve design, which has you connecting the hoses on either side to the compressor and the waste gate of the turbo. The MBC controls the airflow through the valve by the adjusting knob. Loosen the knob and more air moves for higher boost pressure. Tighten the knob down and restrict the flow for less boost pressure.

The AP MBC includes 2 feet of 5/32 vacuum tubing, a flexible aluminum bracket that bolts to the MBC and has predrilled holes for universal fitment, and hardware.

APS Tumbler Delete Kit for Subaru STi and WRX

APS Tumbler Delete Kit Subaru STI 04+ and WRX 2001+

High Horsepower demands a free flowing intake system that is unencumbered by the restrictive stock Tumbler Generating Valves.

The bolt on APS Tumbler Valve Delete Housing is a precision machined aluminum housing that replaces the stock Subaru component (which mounts between the cylinder head and the intake manifold/throttle body assembly) - and dramatically reduces the restriction between the throttle body and the inlet valves at high horsepower levels. Also included in the APS Tumbler Delete system are two precision manufactured Throttle Position/Servo couplings. These components are mandatory for continued correct operation of the tumble control drive/feedback system. Without these components, the engine management system will detect a tumbler valve malfunction. With plenty of room to grow your fuel system, this innovative component not only houses the stock WRX or STI injectors, but also has provision for 4 auxiliary Bosch style injectors for high horsepower applications. Thus providing the WRX performance enthusiast with the best possible drivability offered by the stock injectors and allows for the additional auxiliary injectors to be utilized only when needed at high power levels. The auxiliary injectors can be mapped by most aftermarket engine management systems across the entire RPM range.

Note: This kit does include Servo Plates: two precision manufactured Throttle Position/Servo couplings. Removing the need for Aftermarket Engine Management.

AP GT30R or 35R Ball Bearing Turbo Kit for BIG Power STis and WRXs

We have a GT35R turbo kit on our

Custom Xcceleration 'Monster Long Block' making over 800hp!

See Here

This kit is exactly what you need if you crave Big HP and unbelievable acceleration in your WRX or STi.

includes the following:

-GT30R or 35R turbo
-Silicon hoses
-Custom uppipe
-Custom Downpipe
-Intake (w/breather line fittings)
-MAF housing and K&N cone air filter
-Adapter to fit aftermarket front mount intercooler
-Tial 38mm wastegate with custom teflon steel braided top and bottom oil lines

GT30R-WRX : The custom GT30R-WRX is a great match for the 06+ WRX & 04-07 STI's 2.5L engine, especially if you're looking for boost threshold that is close to stock but want enough airflow for 450+ hp. Almost all the boost is available all the time; even at part to medium throttle!. Boost recovery between gearshifts is awesome with full boost ready even before upshift is complete as the STI lurches forward with shear enthusiasm at the onset of each gear. If you have a built 2.0L and are shooting for 450+ hp, this turbo will work, although it will have significant lag. The modern generation of Garrett wheels, coupled with an awesome wheel ratio, allows even the smaller displacement EJ20 engine to provide adequate motivation to get the GT30R-WRX going for a great powerband. The GT30R-WRX competition-grade turbo still offers the best response and spooltime out of any unit in this flow range.

GT30R-STi : The GT30R-STi has been described as "the right tool to do 500+ HP job." This turbo can support 500+ horsepower on the 2.5L. While the GT30R-STi has a little more lag than the GT30R-WRX (it makes boost about 400RPMs later than the GT30R-WRX), but it makes more top-end power. We do not recommend this turbo for 2.0L cars, unless they are full-race, built-block applications with head work. If you're looking for a 500hp turbo for your WRX or STi that is streetable, and has a decent powerband, look no further.

It is absolutely VITAL that certain steps be followed when installing a new or rebuilt turbocharger on a vehicle. Failure to follow the correct procedures will not only VOID your warranty, but will also cause premature failure, or destruction of your turbocharger.

All these steps should be considered necessary:

Oil starvation is the most common reason that turbochargers fail.

You MUST take the following steps in order to ensure that your turbo gets an adequate supply of oil:

1. Thoroughly clean out oil supply lines and / or oil coolers PRIOR to installing the turbocharger.

2. Change the oil PRIOR to installing the turbocharger using a high-quality engine oil.

3. Install the turbocharger and attach all oil and coolant lines

4. DO NOT START THE VEHICLE YET!

5. You must prime the oil system by cranking the engine over (WITHOUT STARTING) for 15-20 seconds, repeat this at least 3-5 times to get a good supply of engine oil into the turbocharger oil supply system and the turbocharger before starting. 

6. Start the engine and allow it to idle for at least 10-15 minutes before attempting to drive the car.

7. Be gentle with the new turbocharger for at least the first 100-200 miles, attempt to limit full boost so that the bushings can properly break in.

Proper oil changes are essential to the life of your turbocharger, make sure that you change your oil at least every 3000 miles to ensure that your turbo has a long life. 

Important Note: Proper warm up and cool down of a turbocharger is very important.  The vehicle needs to be at operating temperature before full throttle is applied and the turbo is brought up to boost pressure.  Cooling the turbo down properly after running the vehicle is very important as well.  You must allow your car to idle for at least 3-5 minutes when you first start it up before driving briskly, then allow at least 1-2 minutes of cool-down time after driving to allow the turbo to cycle engine oil through the cartridge while temperatures are brought down.

Proper break-in of a turbo, as well as proper scheduled oil changes and maintenance will ensure that your turbo lasts as long as possible.

If you have a problem with your turbocharger, here are some potential things to look out for:

Oil Consumption

Oil coming out the turbine (rear) side on a recently replaced turbo.

We have seen lots of this type of concern:
-Check PCV valve
-Check compression
-Check oil outlet - must NOT be obstructed or kinked
-Check oil inlet size

Most times, especially on new or rebuilt turbos, when the turbo leaks oil out the turbine seal, it is not necessarily a bad turbo. Things such as improper oil drain can cause this. The oil cannot drain out the bottom of the turbo so it passes out the seal. Low compression or bad PCV valves can also cause this problem. These can lead to higher-than-normal crankcase pressure, which will not allow the oil to flow out the drain tube, and again leak out the turbine seal. In some rare occurances, vehicles need an oil restrictor in the oil supply line. Many cars that run very high oil pressure and large diameter oil supply lines will need this to prevent actually blowing oil through the turbo, and straight out the turbine seal.

Oil coming out of the compressor (front) side:

Some of the same problems as above can cause this symptom.
-Check PCV valve
-Check compression
-Check oil outlet - must nOT be obstructed or kinked
-Check oil inlet size

Strange Noises

It is usually quite easy to hear when something has gone wrong with your turbocharger. Rattling, scraping, or screeching sounds are VERY bad.

If you hear a noise that does not sound normal, IMMEDIATELY shut the car down. Make an attempt at minimizing damage.

Oil Starvation

Oil starvation is one of the most common causes of a failed turbocharger, especially a new or rebuilt one. Oil starvation can cause heavy damage to the inside of the cartridge, the turbine shaft, bushing surfaces, etc.

When a turbo starves for oil, material is removed from the bushings, and can be deposited on turbine shafts or bushing races. The turbine shaft is normally warped, which causes the turbine and compressor wheels to hit their housings. Other signs of this type of damage can be hot-spots or burn marks on the thrust bearing, or other internal parts of the turbo.

Agency Power Hard Turbo Inlet Pipe Kit Subaru WRX/STI 02+

There are 2 reasons to change your factory turbo inlet pipe on the Subaru WRX and STI cars. First reason is the factory inlet pipe is very restrictive. Its thin diameter and corregated design reduces air flow and robs your car of horsepower. The second reason is the factory inlet pipe is a very cheap plastic material. When you upgrade to a new turbo, this pipe tends to crack or not fit on the new turbo during installation.

Agency Power has brought you the best solution of a new turbo inlet pipe for your Subaru WRX or STI vehicle. This all stainless steel intake pipe is a full 3 inch in diameter. Its precision welding and features allow you to easily install this hard pipe under your manifold with minimal work. Unlike the competitions silicone intake tubes, there is no flexing, collapse under pressure, or issues with fitment. As well, this intake pipe was designed to use all your factory hoses. No additional hardware is needed. Agency Power supplies you with 2 options for coupler sizes. One is for the stock 2.5 inch turbo compressor inlets and one for upgraded 3 inch turbo compressor inlets. Each inlet tube kit includes hose clamps as well.

This inlet pipe will fit to most short ram and cold air intake kits. It also fits the factory intake pipe. Turbo inlet pipes are available in wrinkle red or fully polished. Each intake pipe includes the black silicone couplers. Inlet pipe fits all WRX or STI cars from 2002 and on.

Available in 'Wrinkle Red' or 'Polished' - $299.99 each

Very well constructed and PWR USA offers a very good warranty. Works well with our radiator hoses, shroud, and thermostat for maximum cooling. No filler cap. Made in Australia.

AP Aluminum Radiator Kit Subaru WRX STI 02-07

For any vehicle, improved cooling is an issue that may be overlooked. When engine temperatures are high, the efficiency of your motor goes down. By providing better cooling capacity, you can maximize your engines performance. Increasing the radiator core dimensions and improving upon the flow design, AP has developed these performance radiators kits. Whether your car is turbocharged or normally aspirated, an upgraded aluminum radiator will give you more performance on and off the track.

The all aluminum radiator features a high pressure radiator cap, aluminum construction, and mounting tabs for a direct OEM replacement. The factory fans and radiator hoses will fit with no modification. This kit is very easy to install and should only take about 1 hour. The core dimensions for this aluminum radiator are 27.25” x 16.25” x 2.25”. That is almost 25% bigger then the stock unit. In addition to having a larger cooling capacity, the aluminum radiators are much more durable then stock. The factory plastic end tanks can crack under extreme heat and pressure. Under racing conditions, your water temperatures can near boiling points. As tested under the intense Arizona heat conditions, the aluminum end tanks and larger core size help keep the temperature down by at least 15F degrees.

In addition to the aluminum radiator, we recommend upgrading to a silicone radiator hose kit and putting a coolant additive in with your fluids to help keep temperatures down.

Radiators include 1.1bar radiator cap with AP logo. This fits all Subaru WRX and STI vehicles from 2002-2007.

APS DR725 Front Mount Intercooler Subaru WRX STI

Professionally engineered performance for 500 - 700 horsepower applications utilizing 50 - 70 lb/min turbochargers.

The legendary APS front mount intercooler has quickly become the benchmark for all front mount intercooler systems for the Impreza WRX. Extremely high flow rates and massive temperature reduction - a level of performance that other manufacturers can only aspire to achieve.

APS has now upped the ante even further with the release of the D/R 725 front mount intercooler system, specifically designed for very high horsepower Subaru WRX and STI engines.

Unlike other systems that require cutting of structural components at the front of the vehicle, APS has designed the D/R Series FMIC with a truly bolt-on replacement unit that not only maintains the structural integrity of the vehicle, but also forms the perfect mount to accommodate the largest FMIC available for a WRX and STI.

Another bonus for the Subaru performance enthusiast is that the APS D/R Series FMIC maintains the standard fog lights!

In the case of intercooling, where bigger is better, APS shoe horned the largest intercooler core possible into the WRX for maximum cooling capacity and engine performance.With intercooler core dimensions of 9.5" x 28" x 4.5" (24.1cm x 71.1cm x 11.4cm) for a surface area of over 266 square inches and a total intercooler core volume of 1,197 cubic inches (19,600 cm3) (the largest by far of aftermarket WRX and STI intercoolers) that's over 4.5 times the size of the standard top mount intercooler.

The APS intercooler core is of internally finned construction and offers significantly enhanced flow and heat exchange performance over the standard intercooler and other front mount intercooler systems, particularly at high charge air mass flow rates. Also, unlike other manufacturers of WRX intercoolers who reduce cost by using deeper cores of small frontal area, the APS D/R Series intercooler is designed with the optimum ratio of intercooler core surface area (over 266 square inches!) to intercooler volume (1,197 cubic inches). The result is an intercooler system with outstanding flow and cooling performance, particularly at high engine horsepower levels of 500 - 700hp.

However, there is more to intercooling than size alone. Fully engineered light weight, cast aluminum end tanks ensure optimum charge air distribution throughout the entire cooling core for maximum charge air cooling and minimum pressure drop. 

The reality of intercooler excellence in terms of performance equals:

-Largest intercooler surface area possible

-Optimal intercooler internal passage volume

-Lowest possible pressure drop

-Highest possible intercooler core efficiency

-Matched to the turbocharger air delivery in lb/min

In other words the greatest possible charge air temperature reduction with the lowest possible pressure loss at the rated flow of the turbocharger - Whilst maintaining good throttle response.

An intercooler drops the charge air temperature, which enhances the combustion of the air/fuel mixtures. This more complete combustion of air fuel mixtures produces higher engine power. 

Intercooler performance is measured by the amount of energy (temperature) the intercooler can remove from the inlet charge air as well as the pressure drop across the entire system. It is important to consider the entire intercooler system and not simply the intercooler core itself.

Pressure and Temperature Data

The following table details pressure and temperature reduction data at various horsepower levels. Note that turbocharger specification will have a significant affect on temperature and pressure data.

Turbochargers with a smaller capacity compressor for example will discharge compressed air at a higher temperature. This results in increased charge air volume (hence gas speed) through the intercooler system to achieve an equivalent mass flow of compressed air. After all, the mass of air available for combustion is the overriding factor when it comes to producing power from an internal combustion engine. Conversely, a larger turbocharger will supply cooler air for the equivalent mass flow of compressed air.

(1) Intake, head, exhaust manifold etc. flow improvements utilized (2) Vehicle Stationary on Chassis Dynamometer.

Never before has such an outstanding production intercooler system been made available for the WRX/STI performance enthusiast. For high horsepower applications, the APS DR725 is the clear choice.

The APS D/R Series Front Mount Intercooler system is supplied complete including every nut, bolt, bracket etc. for easy fitment. DR725 Intercooler above available in Silver Note: Not supplied with APS logo on intercooler core.

Perrin Fuel Rail Kit

Agency Power WRX Fuel Rail Kit

The biggest problem in increasing horsepower on the factory Subaru WRX 2.0L Boxxer engine is the fuel delivery. The factory system runs the fuel in series which tends to cause certain cylinders to obtain less fuel. In higher boost applications, these cylinders can lean out dangerously causing the motor to fail.

Agency Power has redesigned the fuel system to distribute the fuel equally to all four cylinders. As well, Agency Power has designed its 6061 aluminum fuel rails to have the proper angle for the injectors to fit and spray the fuel correctly. The distribution block is designed to bolt on to the manifold for easy fitment. Then the factory fuel pressure regulator is retained, as aftermarket ones are not needed for most applications. The distribution block even has a fitment for an aftermarket fuel pressure gauge sensor if you decide to add that later.

The lines are all steel braided and coated with Teflon insides for better flow compared to rubber lines. Teflon even last longer. The diameter of the smaller distribution lines is dash 4. The larger fuel feed line is a dash 10. Each line is assembled to the fuel rail block and distribution block with AN fittings and Teflon tape. This will never leak or come apart under extreme pressures.

The Agency Power Fuel Rail Kit works with all 2002 and up 2.0L Subaru WRX motors only. Top feed injectors work only for this kit like the factory setup. The Agency Power kit is available in Classic Gold with smoke lines and black fittings.

Agency Power STI Fuel Rail Kit

The STI fuel rail kit gives the Boxxer engine equal fuel delivery unlike the stock setup.  This kit will solve all your fuel distribution problems that the stock STI has when trying to obtain more horsepower.  The CNC machined 6061 aluminum rails fit side feed injectors and utilizes a distribution block designed for maximum flow to all 4 cylinders.  In addition, the Agency Power fuel rail is the only kit on the market with safe, non leaking, and secure AN fittings connecting the lines to the rails.  These fittings will never leak and no costs are cut to ensure safety.  The teflon steel braided lines are coated with a smoked covering for long life, prevent wear from rubbing, and flexibility.

Each Agency Power STI Fuel Rail Kit includes 2 anodized and laser engraved CNC machined rails, a distribution block to utilize your factory or aftermarket fuel pressure regulator, a fitting to run an external fuel pressure gauge, and a complete line and fitting kit.  The Agency Power STI Fuel Rail Kit is available in Red, Black or Blue.  Fuel rail fits all 2004 and up 2.5L STI with side feed injectors.  All lines are smoked with black AN fittings.

Greddy Oil Cooler Kit 13row Subaru WRX/STI 02-07

GReddy / GREX Oil Cooler Kits help prolong the life of your oil and in turn your internal engine components. Hard driving causes higher engine temperatures. Factory oil coolers are normally small water-cooled devices sandwiched between the oil filter and engine block. These tax the cooling system even under normal driving conditions. GReddy / GREX oil coolers are an excellent addition, and are especially effective in harsh driving environments. By using a similar inner-fin core design as our famous intercoolers, we are able to increase oil capacity, decrease oil temperatures, and extend engine and oil life. Our systems also offer an internal (or external) thermostat to allow for quick engine warm up. The efficient core and durable steel-braided lines ensure good flow and a leak free installation.

GReddy e-Manage Ultimate with Plug 'n' Play Harness for '02-'08 WRX, '04-'08 STi

Wire-in for Non-Turbo Cars '99-'06

The GReddy e-Manage Ultimate was engineered to preserve the best features: the use of existing sensors, the ability to easily alter stock settings, & vast compatibility. Best optimizing and fine-tuning for performance modifications, such as; Exhaust, Air Intake, Intercoolers, Boost Controllers, Big Injectors and Turbo upgrades, to mention a few. The e-manage Ultimate does it better than any other system on the market. The Greddy e-Manage Ultimate does what no other piggyback ECU can. The e-manage Ultimate includes the Support Tool CD to access all features from a standard USB cable. E-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools.

In addition to standard airflow-based adjustments, the Ultimate includes added and upgraded features. Included is a PC-based Ultimate Support Tool software CD, with an easy-to-use Parameter Set-up, tab menu format and speedy USB communication. Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition. The ability to switch between 2 preset tuning Maps (i.e. Street or Race program) via externally mounted toggle switches. There are Maps for Individual cylinder adjustment for both Fuel and Ignition. There are also options to convert injection and ignition systems (i.e. group or sequential injection and group or individual fire ignition.) An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. There are also built-in Boost, Rev and Speed Limiter-Cut features. To create super smooth operation, there are various fine tuning Correction Maps to adjust for Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti Engine Stall, and Idle. To further aid in tuning, e-manage Ultimate's improved integrated Monitoring, Map Tracing and Data logging features far exceed any other piggyback controller on the market. Even when not connected to the software, 8 channels of datalogging (at 20msec intervals) can be recorded and stored to be reviewed later. With the Support Tool connected, over 30 channels can be covered. Other new features include: Improved RPM recognition, Warning Settings, Password Protection for individual tuning Maps, NVCS (Nissan), VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and numerous others in future updates.

Some of the best features include:

The ability to both Add and Subtract on fuel and ignition maps A toggle switch to shift between two sets of tuning maps (i.e. Street program or Race program) Air/Fuel Target Map for self-tuning to speeding up initial tuning time Increased number of input and output ports and numerous built in adapters Various Correction Maps (for Acceleration, Speed, Temperature, Ignition, & A/T Trans) Fouled Spark-Plug Cleaning Feature Auxiliary Output Maps A new extensive multi-channel data logging system with map tracing for easy tuning Includes the software Support Tool CD Use of a speedy standard USB cable for tuning, monitoring, and data logging Ideal for optimizing and fine-tuning for performance products like exhaust, air intake, intercoolers, boost controllers and turbo upgrades, the e-Manage Ultimate and do it better than any other system on the market today.

Front Panel

(Dip) Toggle Switch - 2 independent setting can now be stored and accessed via the “Toggle Switch.” 2 separate maps for the “Injection Adjustment Map” and the “Ignition Map.” (For Rotary engines, 2 separate “Primary and Secondary Injector Maps” and “Leading & Trailing Ignition Maps.”) i.e. one program for “street” and one for “race track”.

Serial port - External data (like “GReddy Warning Meters”, and other future optional products) can be monitored and recorded in real time through a data link cable.

Switch Port - “Data logging” and “Ignition Cut” features can be activated with the use of an optional “Remote Switching System” and “Switching Harness”

Option 1 & Option 2 - An additional “Option Connector” is added to the previous “Pressure Connector.” Now any two Options (like “GReddy Pressure Sensor”, “GReddy Temp Sensor,” “Multi-Switching System,” A/F Meter, Auxiliary Switch, Factory Pressure Sensor, or Other Analog Input signal) can be selected using the “Option 1” and/or “Option 2 “ ports.

USB Port - e-Manage is industry first to adapt the USB communication technology. We have improved communication with ability to use standard USB cables. This improvement also enhances the communication speed for more detailed real time monitoring and data recording.

Real Panel

Because of new Features, there are now 3 “Harness Connectors” (sold separately). The 18-pin and 12-pin connectors and the signal pins are identical to the previous e-manage system, while a new 14-pin connector was added for new features. Additional “Vehicle Specific Plug-in Harness” may also be available for certain applications.

Circuit Board

Many Optional Adapters, which previously need to be purchased separately, are now built-in. The internal circuit board contains 20 “Jumper Switches” to accommodate (previously separate) features, including:

Mazda Hotwire Airflow Meter Adapter

Ignition Signal Adapter Socket (Ignition Signal Adapter 1 & 2)

Parameter Setting - The biggest change to this system is in the “Parameter Setting” window. With all the added features, the window is now in a tab menu format.

Speed Limiter Cut Feature - This feature will eliminate the factory speed limiter. (May not work on some vehicles)

Throttle Setting - Any voltage can be inputted directly to set the throttle position.

Warning Setting - “e-manage Ultimate” can illuminate the Active L.E.D. as a warning light for RPM and/or one additional parameter from the menu, by selecting and setting a warning point value (or an unused “I/J CH” can be used to activate a relay to illuminate an external warning light).

Ignition Cut Feature - With the installation of a switch (in the “ON” position), ignition can be cut at a set RPM point

Map Trace

Protect Feature - Each Map has the option to be password protected

A/T Shift Compensation Feature - On vehicles with Automatic Transmissions, ignition timing can be compensated at set shift-up and shift-down points

Channel Change Feature - Vehicles with a distributor type ignition system may able to use group fire or individual ignition systems (Replacement parts and modifications to the wire harness is required) Also, Group injection systems may be changed to sequential injection (Modifications to the wire harness is required).

Map(s)

Airflow Output Map - Previously labeled “Airflow Adjustment Map” is now “Airflow Output Map”. (#)This can now used to eliminate the factory airflow meter. This is done by directly inputting voltage or frequency in to this map.

Anti Engine Stall Feature - The 8 adjustment cells are now upgraded to 16 cells, for even finer adjustment.

Injection Adjustment Map - Fuel trimming in the previous system was achieved by adjusting the “Airflow Adjustment Map” which could also affect the ignition timing. The improved “Injection Adjustment Map” is used to trim and add fuel directly by controlling the injector signal, therefore it will not affect the ignition timing at all. (However with an internal jumper setting change, the system is still able to trim the fuel by adjusting the airflow signal like the previous unit)

Acceleration Injection Map - Like the “Injection Adjustment Map”, the “Acceleration Injection Map” can trim fuel by controlling the injector signal. This is used if it is necessary to smooth rapid transitions to wide open throttle.

Individual Cylinder Injection Adj. & Individual Cylinder Ignition Adj. Maps - It is possible to correct uneven combustion between cylinders, by fine tuning each individual cylinder for more advanced tuning.

Vehicle Speed Correction Map - Inconsistencies due to differences in vehicle speed (difference in load) can be corrected with this map.

Coolant Temp Correction Map (Must be Selected with Knock Signal 1) - When the ECU Coolant Temp Calibration does not match the e-manage’s tuning, this map is used to tune the system at various temperature ranges.

Intake Air Temp Correction Map (Must be Selected with Knock Signal 2) - When the ECU Intake Air Temp Calibration does not match the e-manage’s tuning, this map is used to tune the system at various temperature ranges. (#)This map is also be used when eliminating the airflow meter on a vehicle equipped with a hotwire type airflow meter.

Rev Limiter Cut - For vehicles with a fuel cutting controlled rev limiter, this feature will drive the injectors past the factory rev limiter. *This feature will not work on vehicles with rev limiter controlled by ignition cut.

A/F Target Value Map (feedback tuning function) - By inputting target Air Fuel values in this map, “e-mange Ultimate” will automatically make corrections to the “Injection Map,” if an A/F meter (*high quality) is connected to the Auxiliary Output signal. This feature can shorten the tuning time.

Ignition Adjustment Map - The “Ignition Adjustment Map” can accurately advance ignition timing by controlling the crank angle / cam angle signal.

Acceleration Ignition Map - Ignition timing can also be corrected for a rapid change in the throttle opening rate for a smoother transition into wide open throttle.

NVCS Control Map - NVCS (Nissan Valve Control System) can be controlled with out the need for NVCS Adapter 1.

Analog Output Map - This feature can be used to eliminate the factory boost cut function on vehicles that are equipped with both an airflow meter and a pressure sensor (i.e.: FC3S, Subaru). Also, on some vehicles, the factory feedback range can be adjusted by outputting a corrected throttle position signal.

Auxiliary Output Map - The fixed 4x4 map on the previous unit is now a fully adjustable 16x16 map. Set your own "ON" and "OFF" conditions.

Idle Stabilization Map - If the factory idle control valve is a solenoid type valve, this map can vary the valve’s duration to adjust the injection rate. (#)This is used when eliminating the airflow meter.

Other Added Features

RPM Signal Recognition Improved RPM signal. If the standard RPM signal wire cannot be used, an RPM signal can be recognized though a crank angle / cam angle signal. With an internal jumper setting, the system can even recognize RPM from the negative signal of the ignition coil.

Fouled Plug Feature - When initiated this feature can help clean fouled spark plugs by cutting the injector’s firing at start up. To fix the fouled plug start the engine with wide-open throttle.

Data Log Features

Data Logging - Samplings can be recorded at 20msec on up to different 8 channels on the unit itself and over 30 when using the included software. The data can be recorded even when the PC is not connected.

TEXT File Feature - The data recorded in the Real Time Display mode can now be save as TEXT file. Organizing the data can simplified by opening the data in Excel and creating a graph.

Knock Monitor (Future update) - Knock can be monitored and reviewed.

Ignition Timing Display (Future update) - Ignition Timing can be monitored in the Real Time Display mode.
