Hi guys I have an octavia aum mk1 150hp I would like to know if I can crossflash my maps ecu:06a906032sg 369039 with the maps of octavia rs auq 180hp ecu:06a906032sj 369040?
Some software versions can cross flash without an issue, some have issues. 2 known potential issues you may wanna check on, immo generation, and eeprom compatibility. If all is a match and / or compatible, it will cross flash without an issue. bare in mind, if you flash the wrong generation immo file to your ecu the car will start and instantly shut off, and you will not be able to recover with nefmoto as "immo not authenticated" will keep it from flashing. The best solution is to take the maps from the 180, and transfer them to your 150 file. If you poke around the forum a little bit youll find a some threads covering this. My 2c on the topic would be make sure you at least have a recovery option for when you brick your ecu.
