BMW e90 335d - checksums cannot be calculated HELP
Hi all,
I have very weird problem with one bmw 335d. When i make proper remap, calibrate everything up to 100mg and tried to write file to ecu, everytime ecu is bricked after writing. When i try to make “dirty” remap just decalibrate everything without raising IQ limiters from 80mg stock, after writing car starts normaly and runs without issues. (Tried to write 5 times in a row with changing map by map and eveytime was ok, car starts) Only after raising iq limiters it looks like tool can not make checksums. I let tool to make checksums, never did checksums in winols. Can anybody any solution for this issue ? Thank everybody for a help. Map is read from car, it’s not my remap, i know that it’s a crap. |
