My buddy is a local tuner here and we hooked up to the OBD2 to tune it and it did not conect to my computer. We then took my computer out and tried to tune it and the same thing. An Ascender is identical to the GMC Envoy, and mine has the 5.3 V8. He said the only other vehicle he couldn't tune is the new C6's. Anyone have any ideas? Does anyone have a trailblazer or Envoy with the 5.3 with the same problem?

It's an 04 and the harness on the computer has the green and blue conectors.

Do we need newer software?

What tuning product are you trying to use?

I'd have to ask him I can't remember.

Efilive does support it, but you have to select 99+ ls1 for it to read it. That is if they are using efilive.

If he is, have him just call me and i can trouble shoot the truck.

I think he's using something like CAT or something.
