How to unlock a tuner locked PCM for ls engines

- Finally got HPTuners and our PCM was locked from a previous tune. IT won't read or write to the PCM due to this lock. We short a pin on the circuit board which allows a new tune to be written to the pcm, removing the tuners lock. it works for most ls pcm's. some look slightly different but the pin is around the same spot. Hope this helps

Took a couple try’s but it worked appreciate the videos I thought I was going to have to get a new pcm
is this how they unlock the newer ECUs too? GM Global B E01 Ecms?
Worked for me. Did take a couple try’s.
On gen 3 pcms, I turn off high speed and it usually works well
will this work on a stock Pcm that is locked from factory?
What if it doesn’t let me read it
I had to read this title like 6 times
i have a e38 locked help me please
would you find the way to unlock the e38 ecm? help me please
If I get a gm dealer to flash my ecm and reprogram it will I be able to tune it ?
Yes
