Version software is revision incompatible for tuning

[GamblerZ]

I have an '05 Chev. Avalanche LT that is no longer accepting a tune after returning from the dealership. I restored the stock tune prior to bringing it in and am now getting the following message:

Version software is revision incompatible for tuning
Call you dealer for tech support

Model No. GM-2004

Predator Serial No. 000324

Tool ID No. 9819499DF681F504

Software Rev 2.04
Hardware Rev 1.01

Factory Tune

Tool is locked

I should note that I just got the truck back from the shop for Error Code P0894. The entire transmission was rebuilt due to clutch and solenoid failure. Additionally, they adjusted my settings for the 20" wheels I had installed.

Dealer most likely flashed the PCM to GM's latest version.

Here is a website that you can check: http://tis2web.service.gm.com/tis2web

Gambler, please post up the 8th digit of your VIN so I can tell you what revision to request when you send that tool in.

Thanks

I'm assuming you are looking for what is in the 8th spot of the VIN. That would be "Z". Otherwise, if you are looking for the 8th number, then it would be "2"

OK, you'll need to fill out an RMA request from our website and have the tool updated to the 2.10 revision to fix this.
Did you restore the stock tune to the truck before the dealer reflashed it?

Thanks

[GamblerZ]

Yes. It was my understanding that you should always restore the factory tune prior to servicing to ensure that the Modified Tunes are available on the Predator. Is that not correct?

RMA message sent/received.
