Just purchased an 08 WRX AT that has been 20X swapped. Previous owner had some issues with it and I am currently sorting those out. I am hoping someone might help me locate a good base tune for a 20X swap.
I would try and download the rom outta the vehicle using hp tuners firstly to see if hp tuners support it. I have a 2007/2008 wrx but hp tuners doesn't support the ecu. Had to go to open source to tune the vehicle. But i have hp tuners for the gm and ford platform.
Finally got around to reading the ECU. It read the file but has some unusual parameter data that doesn't make sense. Anyone have suggestions? File attached.
