So the story is, I have a custom tuned bin file I purchased for my car from a very reputable tuner. The issue we are having is the lack of software to load 512kb bin files onto the ECU. Every software he has is only comparable with 1024kb files so we keep getting a “file corrupt” error. We have tried about 3 different softwares but none seemed optimized for the 512kb file. It is a bosch me7.01, but the chip is 512kb rather than the 1mb chip that most all other Volvo ECUs use. I’ve read I can use mpps and boot mode to bench tune the ECU, but don’t have the needs software/hardware. I would like to avoid shipping my ECU to him as I’m in the states and he’s in the UK. Has anyone else encountered this problem? And how hard is it to bench tune if I were to buy the needed hardware/software? I’m just getting into the tuning scene so sorry if my wording is not fully correct. Thanks.
