02-07 Go Fast Bits Respons
Adj. Bypass Valve
Go Fast Bits Respons blow-off/bypass valve system for 02-07 WRX and STI
is much more than simply a noise maker or a factory valve replacement.
The Go Fast Bits Respons valve features the GFB Turbo Management System
(TMS), designed specifically for the purpose of turbo lag reduction. Go
Fast Bits in-house testing facilities have measured a return to peak
boost up to 30% faster between shifts than most factory systems, giving
you quicker on-off boost response and faster effective acceleration
The Go Fast Bits Response bypass valve features their patented adjustable venting system, allowing you to adjust the sound and vent volume on your valve like a stereo volume control. Vent or recirculate your boost and turn up or down your Respons volume as you see fit! The unique Respons adjustability allows you to fine tune your turbo system for better drivability while still getting the traditional atmosphere venting noise. Leave those little noise makers behind and upgrade to a system tunable to your Subaru without triggering that dreaded check engine light and compromising daily drivability. This is a direct factory replacement kit that includes everything you need for a complete install with no cutting or further modification to your WRX or STI.
AP Adj. Blow Off Valve Subaru
100% Atmosphere to 50/50 Recirc
base is designed to use the factory gasket and sit flush will the
factory top mount intercooler and all aftermarket front and top mount
intercoolers. The brass nipple on the side is ridged to ensure the
vacuum hose stays secure and has no leaks. AP designed their Subaru BOV
to be used in two different configurations: The valve can be 100% vent
to atmosphere (VTA) or can be reconfigured to be a 50/50 valve. As a
50/50 half of the air is returned to the intake pipe and half is vented
out. AP includes the return line plug just in case you want
to run the full VTA set up.
Available in Silver,
Red, Blue or Black
Perrin Recirculating BOV
The blow off valve is
essential to all turbocharged vehicles. The purpose of the Perrin blow
off valve is to relieve compressor surge without reducing compressor
speed. This recirculating blow off valve controls boost pressure that
is built up by the turbo and vents it into the atmosphere when your
Subaru is not under load (in between shifts). This prevents pressure
from backing up into the compressor housing, causing the turbo impeller
blade to rapidly stop or even worse, to spin backwards (compressor
surge or backspin). Doing so can be potentially destructive to the
turbine wheel, shaft, and turbo life in your STI.
A re-circulated BOV is the best
because it is one where the boost pressure is re-circulated back into
the intake just before the turbo. This type of set-up is a must for
those that are running a Mass Air Fuel (MAF) sensor. The reason for
this is that the MAF has already accounted for the air that is in the
intake manifold, and if it were allowed to escape to the atmosphere,
the car would run overly rich due to the fact that the ECU still
believes that the air is in the intake tract. A bonus to running a
re-circulated BOV is that the air being re-circulated can be brought
back into the turbochargers intake pipe at a location and angle so that
the air pressure is forced directly onto the compressor wheel. This
will aid even more in helping to keep the turbo spooled up and running
in-between shifts, or times when you are quickly on and off the gas
AP Subaru Lightened Crank Pulley
The AP lightweight crank pulley for your Subaru EJ20, EJ22, and EJ25 motor.
This fits any WRX, STI, 2.5RS and more. The CNC machined aluminum pulley is made from high grade 6061 material and finished in either a Flat Black or Gloss Silver color. Each pulley has the Agency Power text laser engraved. The pulley has been broached for a perfect fit and the redesigned lightweight center gives you the best possible advantage over the competition.
The AP pulley is the same diameter as the stock pulley. Keeping the diameter the same allows no issues to occur with the alternator as under driven pulleys do sometimes. Weighing only 1.0lbs, it is almost 5lbs lighter then stock. This is also the lightest crank pulley on the market. This gives you quicker throttle response as well as more horsepower and torque. Saving on rotating mass results in better performance.
The AP pulley is a great performance part for your Impreza, WRX, STI, Legacy, Baja and Forester vehicle.

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.

Pro Series Universal
Boost Control Solenoid
The EBCS Pro Series 3-Port Electronic Boost Control Solenoid is designed to control today's high performance wastgates with it's ultra fast response and bomb proof design. The PERRIN EBCS was the first and original aftermarket boost control solenoid, and now they have taken it one step further with the EBCS Pro. Main valve body of the EBCS pro is made of corrosion resistant nickel plated brass, with proper seals to withstand the temps and oils seen in a boost control system. The body of the EBCS Pro is made of 6061 aluminum then anodized to ensure it stays looking good forever. These things allow the EBCS Pro to easily survive under hood temperatures.
The OEM type male connector is specific to all Subaru and Mitsubishi applications. Includes additional connectors to allow universal applications. The custom made solenoid coil and valve are made specific to PERRIN specs. This allows the valve to operate almost 2 times faster than other designs, flow almost 50% more air, and work with OEM ECUs without causing check engine lights. To fully utilize the EBCS Pro, an ECU recalibration is NEEDED to ensure no over boosting occurs. High quality nickel plated brass fittings resist corrosion and will not break. For race professionals the EBCS will also accept AN fittings for the best connection possible.
Every EBCS Pro comes with 6 feet of vacuum hose so you can route and mount your EBCS anywhere under the hood. The EBCS kit includes additional hardware for all applications. The PERRIN EBCS Pro comes with a Laser cut stainless steel mounting bracket which will never corrode and provides a solid mounting surface.

Please indicate GT30R or GT35R kit.
Rotated Turbo Tuner kit is designed around the customer who already may
have a turbo, and or a wastegate,and is looking to install them onto
their WRX or STI. As long as you have one of our supported turbos and
wastegates, you can get the same level of performance offered in our
complete Rotated Turbo kits. Every kit includes all necessary items
(except turbo and wastegate) to install on your WRX/STI (with Front
Mounted Intercooler.) With many years of production under out belts,
you will feel confident that this kit will last and perform. PERRIN
Turbo kits are not for the faint of heart and it is best to speak to a
PERRIN specialist before ordering. Let us help choose the exact
combination of turbo and exhaust housings to meet your needs. We can
help you choose the extras that make this project successful from
things like ECU tuning tips, recommended engine internals, injector
size, fuel pumps, etc. PERRIN Rotated Turbo Tuner Kits are designed for
customers that are looking for 400+HP but may already have a turbo or
wastegate. This option allows customers an inexpensive way to get into
our turbo kit or allows them to build their car part by part. Like our
complete kits these tuner kits are designed around Garrett GT30R,
GTX30R, GT35R and GTX35R turbochargers, which can support 600+ Wheel
HP! Each kit includes Intake system, 3" downpipe, boost tube connection
for Front Mounted Intercooler, and all other parts needed for
installation for those who already have a Front Mounted Intercooler.
The stock location for the turbo is limited by its narrow pathway for
the intake which travels under the intake manifold. This narrow path is
no where large enough for 3"-4" intake systems to function. By rotating
the turbo off to the side, this allows for a larger intake, makes a
smoother transition from the Up-pipe to the downpipe, creates space for
a large external wastegate, and of course almost any size turbo we
want. The PERRIN turbo kit places the turbo in the optimum position to
attach to almost every aftermarket front mount intercooler as well as
clear all OEM parts ensuring no damage from the extreme temps.
Garrett GT Series Dual-Ball Bearing Turbochargers

GT30R or GT35R
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 spool time out of any unit in this flow range.
GT30R or GT35-STi : The GT30R-STi have been described as "the right tool to do 500+ HP job." This turbo can support 500+ horsepower on the 2.5L. The GT35R-STi will support 600+ HP. The GT30R 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 for your WRX or 600+HP turbo for your STi that is streetable, and has a decent powerband, look no further.

EXTREMELY IMPORTANT BREAK-IN PROCEDURE!
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 coming out the turbine (rear) side on a recently replaced turbo.
We have seen lots of this type of concern:
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
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 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.

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.

AVO Top-Mount Intercooler
When you are upgrading to a larger turbo or driving the car hard it is important to keep the air charge as cool as possible. Even though the stock intercooler is able to flow sufficient air, it is still only designed for mild driving and stock power levels.
When pushing the car hard, the stock intercooler will heat soak quickly and take a long time to cool back down. This causes the performance of the motor to decline and power to suffer. AVO bar and plate intercoolers are highly efficient and offer a greater surface area than similarly sized tube and fin designs. Many hours of R&D ensure easy and accurate fitment as well as high efficiency required in all Subaru performance applications. Bolting an AVO intercooler onto an otherwise stock engine reaps exceptional results, and a great gain in power on highly modified cars! It has been designed as a drop in replacement for the stock intercooler - no cutting, grinding, or other work will be necessary to get it in. Good for up to 400HP and with less than 1 PSI in pressure drop, you can be sure of reliable power!

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.

Perrin Fuel Rail Kit
The Subaru engine is infamous for leaning out CYL. # 3. The stock fuel rails and lines allow more fuel and pressure to be distributed to the other cylinders. When Subaru owners begin upgrading the engine and adding more boost and more power to this the problem gets even worse. The Perrin Fuel Rail Kit solves those problems. By redirecting fuel to both banks of cylinders as well as the regulator, even fuel distribution is guaranteed. Kit includes billet aluminum rails with stainless lines and fittings. This part is designed for use in all WRXs and STis. However, aftermarket electronics are strongly encouraged.
Fuel Rail Kit - Specify WRX or STi - $619.00
AP 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.
WRX Fuel Rail Kit - $599.00
AP STI Fuel Rail Kit
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.

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

The SMT PIGGY-BACK ECU has been designed to answer the question
“how is my car going to get tuned”?
The SMT 'piggyback' ECU is designed to correct fueling and timing. This is a wire in unit that can be sent to meet the needs of your car. The SMT is simple to install, (must be soldered in) and includes wiring diagrams, and installation instructions. The SMT can be programmed by you using the 'tuning cable'.
The SMT8 piggy-back system has unparalleled performance and a quantum leap of technical innovation. This is all possible with the latest 16 bit DSP processors, crammed full of features that you've never seen before. T
One of the new features is the fully programmable engine protection, which monitors the engine's performance. Should anything exceed the engine's specifications, the SMT8 will gradually reduce the engine's power after a programmable time delay, in essence looking after your engine. This is absolute MAGIC!
The external display output is also new for the SMT8 series. It allows our digital display to receive data from the SMT8 and selectively display the desired value without the presence of a PC. The displays are small with bright attractive LED colour options. Multiple values can be displayed on a single display by simply toggling between them.
An average installation consists of connecting 6 wires to the vehicle's ECU wiring loom, changing the settings of the SMT8 in the setup section of the LetRipp II Tuning Software and voila - you are ready to re-tune the vehicle. An experienced installer can install an SMT8 unit within 30 minutes for a basic installation. The primary features of the SMT8 will take longer to install, simply because there are more wires, but it is worth the wait.
The SMT8 can drive one extra injector (13 ohm) for supplementing fuel at high boost. The extra injector can be controlled via Throttle/RPM, AMP and Engine Temp maps. This allows for precise fuel delivery at boost conditions - a feature which is very popular with turbo and supercharger installations.
Set-points is a feature which makes the SMT8 stand apart from the other piggy back chips. It allows for the implementation of gear shift lights, fan control, idle assistance to mention a few. It has three relay outputs which can be switched on via 14 different signal sources. All Set-point functions can be combined in a logical fashion, and full polarity (higher than/lower than) selection is possible, even switching between the two operating maps is possible.
Two full operating maps (Map A and Map B) are present in the SMT8. Each operational map is capable of being switched into operation in real time while you drive or even when your Set-point function comes true. Switching between the two maps can also be achieved by having an external dash board switch installed, having one operational map for max power and the other for fuel consumption. The options are endless! The LetRipp II Tuning software is able to switch and lock operational maps to facilitate the tuning process.
Two wide band LSU-4 channels can be tuned simultaneously with the SMT8 version 3. This is feature is the major difference between version2. A large 16 x 24 map (384 tune sites) allows for the precise AFR (Lambda) signal modification via the two wide band inputs and outputs. The AFR is mapped via Throttle/RPM, AMP and Engine temperature. Two narrow band AFR (Lambda) probes can also be tuned simultaneously with the two wide band probes. This feature is invaluable for V6 and V8 applications where there are two wide bands probes and two narrow band probes. All 4 lambda probes can be tuned at the same time with one SMT8 unit.
Detailed HELP is available on the unit while the software screen is open. Simply move your mouse over an item and right click and hold down the button. A help description will appear detailing the function of that item. This help feature is invaluable because you get the help from the unit and not from an out of date printed manual. The software manual is also provided with every purchase and should be used as a reference guide, where the item help should be treated as the Holy Grail.
The mapping of all this is done via a high speed USB port and the user friendly, state-of-the-art LetRipp II Tuning Software. All tuning is done in real time and all entered values have immediate effect on the operation of the unit. All in all the SMT8 is the best piggy-back system on the market. It can do everything ... except make a cup of coffee!
