I can not understand you. What is the question? You flashed a wrong file in car? You have a checksum error or what?

Yes, the ECU has been locked in the tuning process ... now we mount signal light on the car (EPC) and i can not delete ... the car is functioning normally ... only this checksum ... I can not delete from ECU...

Always reports -error (EPC)..

Diagnostics is O.K... just-error checksum is not responding to delete ...mount warning light on my car -on displey(EPC)...How do I delete this? ...does not help the new software (update), nothing ... Everything else works normal .. :evil:

What tool did you use to read and write the file? Maybe you have a EEPROM problem.

When we write,burn folders(remap) -to the ECU - ...it was locked ... freeze ... :evil:

hi,

can you describe step by step what have you done.
This is not enough info to solve your problem.

Describe how did you:

1. read original (with which hardware/software you used to read the ECU) ?
2. edited original (which software - winols?)
3. flash (which hardware/software ?)
4. can you post your original here:

orginal-ecu-files

without complete information it is impossible to help.
