Hello,

i'm a beginner to ecu tuning. But my cars ecu was modified by the last owner.

I was able to read the firmware from my car an discussed it with a guy. But he doesen't know what the tuner changed in the ecu's firmware.

Can anybody analyse the firmware and explain the changes?

And thanks for the help ;)

I want to flash the original file. I attachted it to. Can I flash this file back?

There are small, insignificant changes, but not related with engine power.

Hi,

thanks for your reply. I know that these changes are not related with engine power. I wan't to know how these changes effect the engine? I think these are faultcode values and the ECU didn't send a faultcode.
I've closed my egr valve and didn't get any error from the ecu.

Can i flash the attached original file?
