Features such as realtime tuning and launch control will require reverse engineering the stock ECU so we can add our own code. It is in our best interest to only do this on one ECU revision per model so we aren’t duplicating work. The following is a short list with links to the latest revision for several ECUs.
For the moment, only USDM WRX and STis are listed. There are more RomRaider users using these ECUs than any other and it seems to be the best place to start.
