My 2000 Yukon XL has the LQ4 6.0 L Engine and my PCM Operating System is 12205612. I currently have EFILive Pro 6.3. All of the features including bi-directional controls and LS1/LS6 seem to work properly.

I assume that FlashTune will work for all of the GMT 800 series trucks (1999 and after, with LS1 based engines) including my vehicle, but I would like for you to verify that this is your intention.

I believe that this is especially important since the F Body cars have been discontinued here in the States. Therefore, anyone who wants to buy and modify a new rear wheel drive, LS1 powered GM product will be buying these trucks unless it is a Holden based GTO or a Corvette.

These vehicles include:
Chevrolet - Silverado PU/Tahoe/Suburban/Avalanche/SSR
GMC - Sierra PU/Yukon/Yukon XL/Denali/Envoy XL
Cadillac - Escalade Series (all Variants)

I'm not sure that I'm doing this correctly. I'm just trying to bring it to the top again.

Steve,

We will absolutely endeavour to support all 1999+ LS1 based trucks. They are fairly high on the priority list to get compeleted.

Thanks,
That is what I expected, but I just wanted to verify this point. I doubt that there will be any compatibility issues since EFILive Pro V6.3 seems to work fine on my vehicle. I assume that the fundamentals of the software and hardware are pretty well synchronized with the LS1 cars of that the same era, including Holden, F Bodies and Corvette. I'm sure that Delphi/Delco used the same architecture for contemporary vehicles based on the same powertrain.
