hi, because i am new to the ecu stuff, i do not know why this happen, when i try to write on ecu i cant and appears "change of speed not possible", i can read the ecu ok , id ok , but not write , im using OBD port.
Hi. In Kess there is a option where you can change the speed, search for it and try minimum. At the moment i cant check where it is and dont remember, but i know i see this menu. And dont forget -> read the rules!
