I've tried writing to this ecu, and it fails. I've tried. Tractix Openport 2.0 and it doesn't work because the clone doesn't have K-line to connect to the ECU. An original Tractix might work because it has K-line. I've tried PCMflash with PCMtools, and that doesn't work either. There are no errors; it just doesn't pass security checks. I'm going to try buying a legitimate J2534 pass thru device and buy the original PCMflash software with the newer updates. I tried PCMflash on version 1.20 and it doesn't work.
Which is better for this ECU, OKI L66Q592 MMC flash or PCMflash for writing this ecu?
Don't bother trying to read this ecu, you can't but writing is possible I have just not figured it out yet.
