Hi guys, I am running cloned MPPS V16 with dongle.
I am writing a tune onto my ECU which has been externally check summed correctly but when I write it with MPPS it does something to it and check sums it incorrectly and the car gives me an error:
001538 - Internal Control Module
P0602 - 000 - Programming Error - MIL ON

Does anybody know how to fix this or can I use the dongle on a different tuning software to program ECU correctly.

Thanks!

It's a 2006 Jetta TDI with the EDC16U34
I've tried uploading .bin files with both MPPS V16 and Vag Commander Pro. They both give the checksum error.
Thanks!

I believe my problem was with the files I was receiving from my tuner.
I received a tuning file from a user here and flashed it in and have had no more problems. I flashed it with Vag Commander Pro.

Thanks for the help guys!

I am not a pro so not sure if tuning file is good or not but it worked.

What makes a good vs a sh*t tuning file?

Just pour more fuel without exact control and raise boost= sh1tty tune (decalibrated)

Tune made with sense, calculating the numbers to your aim, keeping as its best the balance of the whole engine management = good tune. IMHO.

Just an update. I received a tune from a different tuner who I found on here. Flashed and everything went well, when checking for codes ECU still gives me error.
I was told to flash using Kessv2 or different software as to avoid this error in the future. Have not done so yet. Only problem I have is when car starts it pings and gives 'SERVICE NOW' warning.
No check engine light.
