Problem:
Autotuner is not reading SID209 via OBD. Software says the ECU is already unlocked by another tool. Any solution?
Here is the clue.
Or it means boot the ecu as it can’t be done on autotuner because its been patched with another tool already.
If sid209 has been mapped and unlocked with another tool and you use a different tool it can brick the ecu or you can lose communication.
In this case, better don’t try boot mode with Autotuner.
ECU already tuned. Firmware update with FORscan. Use forscan to load it back to original. or recover ECU with IDS FDRS etc.
