I've read ecu with mpps tool, file is only 32 kb, not 256, its only area of maps, and after modification i have problem with checksum.
Can someone check checksum of the file, i have been moded already tuned file by some "pro tuners" it's disaster of a file. Now car won't start with my file but it will with "ori file"

Ecu is Boch edc15 0281001445

I have done many e46 136hp and have never needed to correct checksum because it was not possible.
Writing the tuned file without checksum always worked.

You can brick your ECU in such a way. I've done in such a way and car doesn't start. Search for software "ULTIMO"-checksuming software good solution when you don't have money for buying WInOls checksums - which are not so cheap.
