Sorry if this is the wrong place for this, as I have some questions which may all be related.
Some history first, I've used EFILive previously but it's been many years, like maybe back in 2014 so I'm basically relearning. I've since sold that V2 and the vehicle I was using it for. Since then, I've acquired a different vehicle and purchased my friends (used) V2 that still has 1 VIN license available. I'm not sure when the last time he used it was, but probably prior to 2015.
My newest project I'm attempting to use V2 on: 2002 GMC Sierra, 4.8l and 4L60E. This vehicle has a mild cam/headers/exhaust and has been previously tuned by a shop using unknown tuning software. I know little about that history. I do however believe the transmission tables or the gear ratio/tire heights are messed up in the current tune file, because it shifts at very high RPM at part throttle (hence the reason I bought the V2).
After purchasing my friends V2, I downloaded the V8 software and installed it (note: I did not download or install the V7.5). I performed the firmware check/update on the V2 through the V8 software and it is now up to date. I then went to read the tune from the GMC and attempt to license that PCM/VIN to the V2, but it's coming up with error $0333. I've searched this code and I think I can perform this procedure linked here: https://forum.efilive.com/showthread...016-Error-0333 but my question is, what if the previous tuner of that PCM has locked it? Should I just attempt to read the PCM tune first? Obviously I don't want to waste a license on a PCM that could be scrap to me, so I'm not sure how to proceed. Since all this, I have downloaded the V7.5 and installed it but that is where I'm at now.
Any help is greatly appreciated.
Thanks,
Mike
