MoTeC M800 Plug-In ECUs are fully programmable, direct replacements for factory ECUs on a select number of popular vehicle models. Based on the M800, they control the latest automotive advances such as continuously variable camshaft timing and drive by wire throttle.

Complete with an OEM connector, M800 Plug-Ins are convenient and cost effective to install because they eliminate the need to rewire the vehicle. They simply plug into the factory wiring harness using the original sensors, ignition modules and fuel system. The units are built to operate with saturated drive fuel injectors.


Currently there are M800 Plug-In ECUs available for the following vehicles:

Subaru WRX and STi: most models from 1999 – 2008‡
Mitsubishi Evo IV – X (RS)
Mitsubishi Mirage/Colt
Proton Satria GT

‡ The ‘08 Subaru M800 Plug-In disables some factory electronics and is therefore not suitable for road use. Race and rally vehicles should be fitted with a MoTeC SDC3 to control the centre differential.

Please supply all vehicle details to your dealer, who will be able to order the right model M800 Plug-In ECU for your car.

Vehicle specifications on the same model can vary between countries (e.g. Japan vs USA vs Australia), so it is important to specify the original country of delivery.
