I recently purchased an SCT x4 handheld tuner with the intention of getting my car a custom tune. When I was attempting to flash the preloaded tunes I got an error 110be, unable to unlock PCM. I am able to data log the vehicle and read codes so I do not believe it is an issue with the device. I checked the PCM and there is not a chip on it, so I suspect that a previous owner had the car tuned at some point and thats what locked it. So what other things should I try? What are my options if the PCM is indeed locked?
Thanks,
