Engine Management

Xede 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.

Bullet Custom Reprogramming of your Factory Computer


Our Bullet Custom Reprogramming and Licencing of your factory computer delivers incredible power and torque at a fantastic price point.

There’s no piggyback ECU, no rewiring, and no need to budget for labour for fitment – just straight up performance.

How Bullet Custom Reprogramming of your Factory Computer Works

Using specialised software, we access the information of your factory computer and download a copy to our tuning laptop. We then begin the process of editing numerous tables that affect everything from the fuelling, ignition timing and dozens of other factors so that we can deliver a tune that is custom designed for your specific needs.

We then perform a power run on the dyno whilst we scan the factory computer to see what adjustments are required. This process is repeated until we have liberated as much performance as is possible from your setup whilst doing so in a safe and reliable manner.

The benefits of custom reprogramming of your factory computer are numerous as how you use your vehicle is going to be unique. Whether that be for off-road torque, towing of heavy loads, performance touring or perhaps a combination of each – we ensure you will enjoy the gains for years to come with complete peace of mind.

The cost also includes the licensing of your specific VIN number to the software, as well as all dyno time and a print out that displays the gains from your custom tune and any other modifications. Our custom reprogramming is available for most vehicles manufactured after 2008. Call us for details on your specific application.
