2007 Yukon Denali 6.2 Problems

[SubTexel]

*Sigh* I went to install a tune on my Denali after getting some time to do it.

I plugged the Diablo in, select performance tunes, and I get an error stating that my vehicle is not supported. D'oh. What do I need to do to fix this?

Edit: I am using the U7194... With the 8r06 firmware.

Anyone?

make sure the 8th digit of the VIN= C, 3, 0, J, K, Y or 8... if it's something different than any of those, then your vehicle is not supported...

if it IS one of those, then I'm not sure and you'll have to wait for Mike to chime in...

It's an 8... (6.2 Liter L92)

First suggestion I would make is to try the 8r07 revision.
If for some reason it still does not work, please give us a call with the tool powered up in the truck.

Thanks

Guess third time is a charm, plugged it in a couple of times more and it finally worked...? A little odd, oh well. Still need to download the update. Thanks! (BTW, nice increase but I wish the TM was actually reduced). Much better than stock, but lots of room for improvement. (Off to do a dyno tune tomorrow)

if you're going to get a dyno tune, make sure you restore the original backup to your vehicle first!
