The Perfect Solution to a Powerful Engine Management System


XMS4 - XTREME MANAGEMENT SYSTEM - C GROUP


XMS4 - Group C

The XMS4 C Group consists of two different modules, in the top-of-the-range of XMS4 products. They are ideally suited for 4 to 8 cylinder engines with "fly-by-wire" ETC (Electronic Throttle Control), and are available with:

4 to 8 x 2Amp Direct Injector Drivers

4 to 8 x Ignition Signal Outputs

8 x Set-point Outputs

Wide Band LSU-4 Controller

ETC Controller


The XMS4 C Group product range comes with a maximum of 8 x 2Amp injector drives, and up to 8 ignition signal outputs.

The range offers the BEST "Features for Cost" in terms of performance. The XMS4C can be Sequential or Batch, depending on the installed hardware and the availability of a CAM trigger input. The XMS4C offers idle control through the ETC, as well as a settable ETC operating algorithm. Launch control (with ETC or without) is standard.

Like all other modules in the XMS4 range, the XMS4C has a soft or hard fuel cut and 16 different Set-point options, which can be logically combined. This allows the setting of "Shift-Points" and the control of other tasks in the engine bay. The XMS4C range includes ALL the features of the other groups (XMS4 A and XMS4B), but includes an ETC controller with simple "straight-line" traction control.

As per the other XMS4 A and B groups, all XMS4C modules boast the awesome LETRIPP SOFTWARE features, such as; remote master map switching, extensive set-point control and many PC screen display options. All modules have the 2.0 USB interface for quick tuning.

If the "Rolls-Royce" version of the all NEW XMS 4th Generation is what you need - look no further than the XMS4C product range!
