Thann you

Hi m'y friend

Concerning Tprot (tuning protection)

I did not understand exactly how to remove it

Before removing Tprot When reading ktag or Kess

Says Maysaj I protection exists and can not read possible explain the method of reading ktag or Kess

Thank you for the interesting topic

You need to read the file first, TPROT is to keep you from mofiying the software, Tuner protection. So in order to make OBD writing/reading safe and be able to normally read and write the ECU you need to remove tprot - so you need to read software, make mods as described and then checksum and write and you will after this, then be able to R/W by obd tools without problems.

RE: How to remove Tprot on VAG EDC/MED17x ecu
When ksuite CAN R/W option able via OBD whit Kess V2.
I ever read TC17xx whit KTAG in Tricore Mode, press PATCH button, load BCK ALL file and write it on ecu automatically.
Now i mount ecu on car, read whit KEss V2 in serial MOde OBD whitout problem, and i start to mod whit file read whit kess v2.
In second case, for example EDC17C46 or C64, when Kess v2 can WRITE ONLY, missing READ button, i read and write whit ktag a patched file.
OR directly write PATCHED file whitout TPtrot in obd mode, and write directly tuned file based on patched file Tprot OFF.
Alientech send whit online form FILE just patched TProt OFF read to write, included new EDC17CP74 for example.
Now is possible tuned by OBD BMW F series whit EDC17C50/C56 and others
