    No worries 👍

    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.

    Firstly, wait until you have the PCM hardware type ie the vehicle in your workshop or have the customer send you a photo of the sticker on the side of the PCM so you know what the hardware is in preparation.

    If you don't have the workshop version & access to the strategy list, once you know what the hardware is, ask if someone can help with a strategy for PCM hardware APS-***, ASU-*** or for whatever hardware it is. Also provide other info for the strategy/TearTag needed....ie you want a turbo manual strategy, na manual strategy, turbo ZF6 strategy, na ZF6 strategy. That's for you to decide.

    Once you have found or someone has provided you with a strategy/TearTag from the Falcon calibration list, the simplest process is to step back to the start of this thread & follow "Overwriting Tuner Lock"

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

    No worries. I guess you'll need to wait for the Patrol to turn up so you know if it is in fact tuner locked, has a custom OS or what you're dealing with. With any luck, it'll have the APS-234 FG turbo PCM.

    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

    I assume you're talking about a conversion in a car that's not a BA/BF/FG/FGX. If that's the case, then matching the TearTag isn't as critical. If you have the workshop version, you can filter the calibration list by PCM type eg ASU-224, APS-234, then filter to trans auto or manual & pick a strategy. NOTE: If it's a ZF6 vehicle, make sure you pick one with a TCM calibration listed.

    You could normally use the PCM part number on the sticker on the side of the PCM as a reference to what the stock file would be but it may not be correct. It may have been overwritten for your conversion ie if it was originally a FG Turbo auto PCM, it may have had a manual strategy flashed to suit the conversion.

    If you don't have the workshop version, provide some info on your conversion, your PCM type, gearbox, na or turbo for assistance with a TearTag/strategy.

    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.
