I'm working on an '03 trying to tune it with an SCT Livewire TS. I understand that it needs to lock the VIN and the strategy to download a tune. Problem is, it won't lock the VIN and i don see a way to manually enter it. The strategy locks in just fine.

I spoke with SCT prior to realizing that it wasn't locking in the VIN and they said that the truck probably needed an updated flash. Well, had it flashed today and it still won't lock the VIN and download a tune.

Any ideas here before calling SCT again?

 

Some 03 6.0s have an issue where the VIN won't show up properly. We ran into that beta testing at Dashboss.

No clue what it is or how to get around it though.

Thanks Josh, the guy that flashed it for me is an ex dealer mechanic, he said the same thing.

 

And make sure it's not one of the tuners that only let it tune 5 times and then your out of tunes.

The 03/04 tuners, some are like that. Had to send mine into SCT to have them unlock it.

 

it should let you tune as many times as you want on one truck.
but it will only let you put it on 5 different trucks. (unlocks)
and the previous truck(s) must be returned to stock, or it will still show as married.

 

That's the way it normally works, but earlier versions of the SCT Touch Screen Extreme and one other, don't know the number of the other model.

My tuner was only used by my truck and then locked itself after 5 times tuning only my truck.... I had to send it to SCT to get them to unlock it for my own use. They did it for free, just that the early editions they made it work only 5 times. Not sure why, doesn't make any sense as my gasser used an SCT tuner and never did that... why would they institute something like that is beyond me. The counter was only activated if you returned to stock... you could change back and forth from tune-tune, but go back to stock and it counted to 5, then locked up.

I always return to stock, check codes for something the tune may be hiding... and recommend doing that always as the tune may be compensating for a parameter or tuned out/off something you don't know about. Why you always read about going back to stock if something goes wrong and your struggling to figure out why.

I won't own a truck not tuned and always used SCT tuners... with custom tunes of course since 2001.

They re-programmed my tuner, it now will let me do as many as I want, but only one truck at a time, its locked to my truck.

Now my PHP FICM tuner is a different story... yes, I'm running two tuners.
