Mercedes EDC17C66 ECU Write & Checksum: PCMFlash vs Foxflash
PCMFlash vs Foxflash which to read and write Mercedes EDC17C66 ECU?
Model example:
Mercedes V-Class 2.2CDI 2015
PCMFlash:
Read over OBD ok, Write via OBD ok, checksum no.
Bench read ok, bench write ok, checksum by foxflash.
Check your cars for previous ecu change before doing anything, it can cost you couple of hours to resolve a simple issue. The car was tuned from someone else, and it had a different checksum, when i did a read i forgot to uncheck the checksum check which after read couldn’t do a correct checksum and that’s why the car didn’t want to start. Later i tried to flash ECU with Launch X431 PAD V with original file, but still the same. After that i flashed the file i took out from the car, took out the ECU and did it on bech with Foxflash and corrected the checksum with Winols for the whole file. Which resolved the problem.
