Each ECU is different, so always refer to our guide for supported methods.
For unlocks that support Bench, the AutoTuner Tool is guaranteed to be compatible.
For unlocks that support OBD, the AutoTuner Tool is guaranteed to be compatible. We can't guarantee all tools will be compatible, but we don't lock anyone out.
We're doing the unlock in house at our headquarters in the USA. Typically they are shipped back the same day we receive them. We process ECUs during normal business hours: M-F, 8-5 Central. We ship UPS Next Day Air in the USA, or UPS World Wide Express internationally.
Nope!
We need to protect the unlock method. Once it's known the unlock can get patched by the manufacturer and then everyone's locked out again. Secondarily, since this unlock method isn't really known, we have to take steps to protect the work.
