Gday bill. Just an update. The tune was indeed locked, I followed the guide and coupled with the info you gave me, all went well. Loaded stock file then made the necessary changes and hit the key. Fired up. One odd thing that did happen though was after one of the flashes I did I found a whole heap of parameters had changed (not of my doing) as a result the car went from running perfectly before the flash to running poorly, going into limp mode and cutting the throttle off. I ended up having to go through everything and comparing it to the stock file to change it all back. Most of it was to do with idle parameters. Things like idle in neutral had changes to “0” instead of 600rpm. Found it quite odd. anyways, crisis’ everted and all is well. Thanks again mate. cheers Chop.

Mate that’s awesome. Thankyou very much. That’s a massive help.

This is the ecu. I’m away from my laptop so not sure what strategy it would be.

Legend!! Cheers man. 😎

Sorry should have mentioned I have the workshop edition. thanks. that’s given me the confidence I was after to tackle it. cheers Bill.

In any case is there a simple way to just re-write the pcm and start from scratch regardless of what’s on it currently? I’ve not had to tackle this issue to date so if there’s any links to treads explaining it I’d be much appreciated

Thanks for the reply bill. it’s for a customers car, I’m yet to physically see the car and the info I have is that it is a fg na+t conversion into a partol using the patrol gearbox (re4) the owner had another workshop interstate create the standalone harness and they modified the pcm to suit (the car runs and drives) but the issue is (according to the owner) the said workshop tuner locked the file. So it would appear I would require flashing a stock file over the top of the locked file and starting again? im lead to believe it’s a stock fg turbo harness that’s been used. edit: I am new to pcmtec but not tuning itself.

How do I go about unlocking/returning a pcm to stock in a conversion situation when there is no tear tag available to me?
