No start issue

[Jackpine]

Right, Lars - it's not really clear to me though if the truck seems to be running properly at Level 0. It started, and since the codes weren't cleared, they were displayed. The last code you mentioned (I guess when it didn't start), was: P2104 Throttle Actuator Control (TAC) System - Forced Idle

So, everything seems to involve the Throttle Position Sensor and/or the Throttle Control, which makes sense because the throttle control relies on sensor readings to tell it where things are. Remember, there's no direct link between the pedal and the throttle body in our "drive by wire" trucks.

When it started in Level 0, did it seem to run normally? If it did, then I'd have to say there was a fault in the tune file. But I wouldn't expect a tune to muck with the sensor readings and it seems to me there's a "cause and effect" relationship between the sensor readings and the control positions. I do think Bill's tunes might bias a control value though. It seems a bit like a chicken and egg problem to me - which is first?

And, I just realized - you didn't say if you are running "canned" or "custom" tunes yet. I was assuming "custom" tunes. Which are they? Maybe, if it's canned tunes you could just update the "calibration" file using Pegasus. Looking at your Serial Number, I think you still have the canned tunes, right?

However, I DO think we need to bring Bill into this, so I'll try to do so.

Sorry I've been a bit unavailable myself - I'm dealing with the aftermath of a broken water supply line to the house we rent out and the resultant flooding of the interior!

(Are any of us having fun yet)?
