Been searching and searching for last hr and can't seem to find enough information that can lead to a possible cure for my current issue.
I have someone making me patches for my 2011 STi and I have installed and been using the beta of ECUFlash 1.43.x with the newest OP2.0 firmware.
The rom file provided to me has incorrect checksum value's and is causing ECUFlash to crash on my windows 7 computer. Before editing the roms XML def i can load all my previous maps just fine since they have the correct checksum. (see screenshot)
1. Is it possible to use ECUFlash 1.42 with the openport 2.0 that has the beta firmware?
2. Is it possible to downgrade firmware on the openport (tactrix cable).
3. something im missing?
