So I got a laptop and gave another run at the RAF using the desired air flow last night. After I did it, I noticed that the original tune was not set up for a 90mm TB. Today I adjusted hat number and re-did the RAF run. While messing with that and then re-setting the IAC, I came to realize that the idle was not following what it should. Looking into it, I figured out that the thing thinks its always in gear and will only go off the in gear idle speed target. The only reason I can think it would do this is because it does not have the black gear selector box on the side of the transmission. From what I can remember without pulling the seat and floorboard out of it is that the harness does not have the pig tail for it either.
So will this really have an effect on it? It is an off-road vehicle only anyways.
On the topic of it being off road only, I would like to set it up so that the TCC is always locked. With it being a 4L80 it cant lock in first which is fine for crawling, and then 2nd and up it would lock up and stay there. Does anyone have any pointers to do this. I have looked into it a little bit, but did not have the editor with me so I couldn't follow along and need to go back and find what I did find.
With doing the RAF by measuring desired air flow, do I need to do it multiple time, or is once through fine? I would imagine going back to the LTIT might dial it in some more, but if its just fine adjustments, it would be something I could take more time to deal with latter.
