RomRaider hasn’t historically had any support for GM vehicles, which is unfortunate because most of the GM tuning tools are either expensive or cumbersome.
But now that there is open source reflashing software (http://pcmhammer.org) and free reflashing software (http://ls-droid.com) we’re closing to having RomRaider support for some GM cars from the early 2000s. The main things we need are conversion of XDF definitions to RomRaider’s XML format, and a good data logger.
