Seems like I have to depress the throttle a bit under cranking, hold for a bit to keep the rpm around 1k. Then I slowly let off the throttle until the car almost dies and then it's like something picks it up, and then it idles fine after that (at least until the next restart) Doesn't seem like it's rich or lean issue either as my wideband will be at 10 on a cold start and it does the same thing as 13 - 14 on a warm start.
Just to recap I started with the stock tune, scaled for +40's, scaled for 3-bar, adjusted the WOT and PT density tables to 8529 as suggested by Rob. I also copied the spark tables from the +40 tune. Once the car does decide to idle, it runs great, still a little rich on WOT, but I have yet to do any data logging on any WOT runs yet.
Just wondering if anyone has any suggestions as to what to try to get my car on idle.
Any help is appreciated.
I'm not sure if I'm thinking in the right direction, but to me, almost seems like the AIS might be sticking. Currently not showing any codes.
