Hello If i have simos18.1 for chhb engine with immo off When i tried instructions unlocked then flashed it wiped immo data i guess What steps without touch immo data blocks to upload tune? because editing fullread write (iflash files) on bench as you know to get back immo and car run.

Thanks for your efforts

Immo Off on Simos18 is normally done in the Application Software by patching the immobilizer module's code rather than in EEPROM/DFlash as it has been done in some past ECUs.

Each time you full flash you need to flash a file with modified Application Software with Immo Off. If you flash a stock FRF or a BIN without an Immo Off applied, the ECU will re-lock.

If you don't want to flash patched ASW each time, use Flash Calibration to flash only the Calibration area.
