RomRaider is a free, open source tuning suite created for viewing, logging and tuning of modern Subaru Engine Control Units and some older BMW ECUs (MS41/42/43). The intuitive tuning interface and powerful datalogger are modelled to be familiar to experienced professional tuners while providing all the power of expensive commercial products, without license fees. RomRaider is developed and supported by volunteers working on their own time. To support their efforts please consider making a donation separately to RomRaider.
This project builds on top of the existing RomRaider framework by providing XML Definition files that allow RomRaider to convert the underlying hex into human readable values. This is the really complicated bit; making sense of a bunch of 'gibberish' and creating table descriptions to convey the underlying logic to the user. Several hundred hours of my time were spent disassembling code and writing these Definition files so you can tune these ECUs like you would any other using data-driven techniques.
To get started tuning, setup your computer to install all the necessary software and configure it. This can be done easily using:
