This website contains some information about modifying the Subaru Impreza Turbo (same as WRX - excluding Japan) - in particular ECU related performance/economy modifications. Most of the information gathered here is as a result of my boost/ignition controller project - the aim being a dashboard mounted controller switchable between "Economy", "Normal" and "Performance". The main drive behind this project is my interest in electronics and computer control, and although it's challenging to make the car "go faster", it's also challenging to make it more economical! Basically it's a bit of fun, although I am considering a commercial spin-off from the project.
Disclaimer: Most of the information has been gathered from experimentation on my UK 1997 model year Impreza Turbo, and therefore may not be representative of other variants or even other cars of the same model and year. The information contained in these web-pages is presented with no warranty with regard to its correctness or validity.
