Hello everybody,
I need help for how to write TprotOff file with Kess clone via OBD to tuned EDC17CP20. (Kess is verified working on some other cars)

What I've done:

1. Opened EDC17CP20 and read it with Ktag (Full Backup VAG Tprot P427)
   
2. Wrote Stage1, EgrOff and TprotOff file from a reliable tuner with Ktag
   

Two times taking out and in the ECU was difficult and took more than 3 hours for each step.

Since step 2. the engine runs bad in idle (800-1500 rev/min). We would like to test only TprotOff file but unfortunately Kess clone can't write it via OBD even the tuned ECU has already TprotOff.

Attached is the ori and TprotOff file. Could anybody please help me how to modify (Checksum?) the file to write it via Kess to OBD?

best regards

@MahoJohn
I'll try it out and report soon

It doesn't work also.
I repaired the Checksum by myself but Kess clone could'nt write it via OBD to ECU.
