How about checksumming the file before writing it?

Wouldn't MPPS correct checksums? According to AMT Cartech it should: "It offers like most other tools reading / writing operations and checksum support..."

I will try to make it!

I correct the checksum with the me7sum.exe and check with me7check.exe and found no erros!

Not genuine!

Its a cracked version.

I read the original file and save on my HD

I edit on file the KRKTE because i install new injectors and save the new file without correct the checksum.

In MPPS, i click in WRITE and select this new file, when the work its complete, the problem inform to switchoff the key.

after it, i disconect the MPPS (EOBD2) and switchON and start the engine fine! switchoff.... when i try to start again the engine not work, the fuel pump not work... all not work!

and now... when i try to write i new file with the corrected checksum the MPPS dont found the ECU!

But i will try to make it, that the ddillenger say!

mpps has been perfect at checksumming for me

I bricked my ecu after a couple goes with mpps. it can fix them pretty easily, dont worry

I make it

unplug ecu for 5 minuts and plug back, i dont start the engine, the key is off.

but the problem still "ECU not found"

just boot it and will be fine
