Tuner Locked my PCM!
The Best V8 Stories One Small Block at Time
If it's been tuned and has had a custom OS applied, you cannot tune it with a different software.
In other words, if it was tuned with HPT, and a COS applied, you cannot tune it with EFIlive. Conversely so, if the same was done with EFIlive, you cannot tune it with HPT.
If it is truly locked, you will not even be able to read it.

Good luck dude!
This is the same situation if someone is using a hptuner custom os.
The Fake locking is only due to the things in the background of the tune. Tables are being used differently and if you would just open it up in another program and not know that the tables are being used differently, there would be potential for engine failure..
Made sense to me.
i do this almost every day
Made sense to me.
In my case I came in only looking to get my Stalling issue fixed. I left MTI Racing with a locked PCM, my car still stalling, and my wallet $600 lighter.
I don't know anything about tuning, HpTuners Calibration Details screen it states "Locked" under Tuner Lock Status, but i'm able to log a run and look at tables. Spoke to tuner, they checked my file (not car's pcm) and says its not locked.
