    On todays episode of tuning and affraid....

    So I bought a non running truck, threw money at it until it was done and with the help of Ed Mowton got it running. Unfortunately I got busy, he got sick, and we never got back to beating the tuning knowledge into my knuckle dragging self. I dusted off the Hp Tuner box and cables today and took my wife's truck (Bumblina) for a spin to log some data which I have attached below. The biggest issue is I'm getting a P0706 code anytime the truck cruises at 65mph, I'm not sure if I miss wired the computer or I have some other issue. Any information is appreciated, I am way over my head on this tuning thing. I also have thick skin so no need to mince words.

    Is the 80e being controlled by the computer? That code shouldn't be a tune issue I wouldn't think anyways. Likely an issue with the prdl switch or harness I would think.
