This article quotes one user’s feedback:
ECUHELP KT200 II is tested to fix a planted PCR2.1 in int writing flash.
So there sure in boot but it didn’t work, the flash was planted, impossible to inject anything, tricore password doesn’t work either, it’s a calculator that planted writing with kess clone.
I managed to force him the password that didn’t want to take I had a backup customer with KT200.
