Engines & Parts / Services / Engine Management



The XEDE 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. It has the additional functions of two stage intercooler water spray control or potentially any other on/off or PWM function including injector drive for an additional injector. The XEDE can generate data logs and importantly can also store two separate programs which can be changed at the flick of a switch while driving – 98 Octane or 91 Octane fuel maps.

The XEDE Processor is a sophisticated tuning tool that gives any dyno programmer control over the engine management system without having to learn the fine nuances of each vehicle’s engine management system. The web based XMap software is available free to custom tune for accurate results.

How the XEDE Works:
The XEDE Processor integrates with an existing (usually factory) Engine Management System. The operation of the XEDE is to modify the signals from the Air flow meter / Map sensor and the Crankshaft position sensor before the factory ECU sees the signals. By changing the values of these signals, the resultant outputs from the ECU will be changed.

The benefits of using an XEDE over other tuning options are:
Most factory parameters are retained
Cold start functions
Idle control
Knock sensor functions
Closed loop control
Limp home operating strategies
Fan and Air Conditioner controls
Immobiliser functions
