XEDE Processor

The XEDE Processor is an interceptor style Engine Management System. It generates changes in fueling and ignition timing by changing the factory ECU’s load and crank reference input signals to improve the factory tune, specifically to suit an aftermarket exhaust, engine modification or supercharger on vehicles that we cannot tune directly through the factory ECU.

3XEDEIt has the additional functions of electronic boost control and optional dual maps to deliver individual tunes which can be changed at the flick of a switch while driving, e.g. High/Low boost or Power/Economy programs. Two stage intercooler water spray control or any on/off or PWM function including injector drive for an additional injector can be incorporated and controlled using the XEDE Processor.

How the XEDE Processor works


The XEDE Processor integrates with an existing (usually factory) Engine Management System. The operation of the XEDE is to modify the signals (Voltage or Frequency and Crankshaft Reference signals) before the main PCM/ECU sees the signals.

By changing the values of these signals, the resultant outputs from the PCM will be changed. If, for example, we effectively reduce the voltage that the PCM sees on the MAP sensor wire at Full Load, the PCM will see a signal that equates to less load. Using this modified input signal, the PCM will open the injectors for less time as it expects the engine is under less load and therefore requires less fuel, thus leaning out the mixtures. Moving the crankshaft reference signal will move the ignition timing (timing advance).

Injector Drive Mod


The XEDE Processor can support auxiliary injector control for up to 2 injectors, however your LPG injectors will likely need a separate controller. The XEDE system works primarily as a piggy-back system by adjusting the original sensors and allowing the factory ECU to drive the original injectors, coils etc.

The extra injector drive of the XEDE is mostly used to add additional fuel when a supercharger or turbo is added to a naturally aspirated engine configuration and the original injectors cannot supply enough fuel for the engine with boost pressure, this feature is purchased separately when ordering your XEDE Processor.
