Hi everybody! I have a problem with my mpps. I read the ecu first and save the original file to my pc. Then I start to write a modified file and when it was on 99% it said Checksum Error. I tried to write the original file but it says the same "Checksum error" and now the car is dead.

I hope someone can help me and the will run again.
I would be gratefull if you also could tune this file for me :)

Car info:
http://upload.bg/?get_file=400cdcef8...b813c45a929b44

And the original file:

6JF are used only in 70hp, the maps are inside the MPC5xx micro and full read is approx. 440k-450k
6JF is the old ecu and can be done by old galletto,
or try to write with MPPS in " recovery mode " - slow speed
If this still dont work you need to do it in boot mode or bench

I tried in recovery mode but the error came in again :(

Does anyone know how to write the file in boot mode with mpps ?
