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-fileswithout complete information it is impossible to help.
