Closing in on a problem

[1great40]

Hi Guys,


Ii h ave been away from working on the truck until a few days ago. I'm in the process of getting an old laptop cleaned up and I'm going to download TunerPro.

I have no response from Robert about the cable so I'm looking elsewhere for one. One thing is for sure...I need to look at my IAC counts when I shift from Park to Drive..From what I can tell there is no control whatsoever on the part of the computer as to where the idle speed is set. I need someone to explain to me the difference between open loop idle and closed loop idle. Also I'm thinking that my minimum air adjustment is off and that may be interfering with the % TPS? I'm hoping to learn a lot by looking at what the engine is doing with TunerPro.
