Welcome to the Evo ECU Wiki!
This wiki has the goal of detailing, with community contributions, how to tune, patch, and log your stock ECU, but it isn't the only resource available to you; please see our helpful links page for other sites that provide useful information.
But wait, there's more! We also have mirrors set up for a variety of software packages, documentation, and other bits and pieces that folks find useful in our mirror section. If you're looking for an obscure ROM version, an old version of EcuFlash, or some other odd bit of software, there's a good chance we might have a copy of it here.
Throughout the pages of this wiki many acronyms are used, if you have an confusion over any terms please visit the Glossary.
There are also many tables that are specifically referred to in ECUFlash that may not necessarily make sense to you. Please visit the ECUFlash Specific Glossary for an explanation of what these tables do.
Tuning is the name for the process whereby you alter the fuel, ignition, boost, and other variables to influence how the ECU controls the car.
Patching is the new name given to modifying the code of the ROM. Through ROM modification various features of the stock ECU can either be improved or entirely new features can be created.
The term Logging refers to obtaining and recording data from the ECU to be used for tuning purposes.
