Tuning for idle AFR-realtime
I've been battling an issue with my car not idling when the motor is cold since day one of the motor swap, 3 years ago. I've been over everything so many times including rigging the AAC valve open. I literally have to hold my foot on the throttle till the motor comes to temp for it to idle, or she stalls.
I've finally decided it is a tuning issue as my AFR's between a hot and cold motor are basically backwards. Cruising is slightly richer than I'd like and WOT is perfect where I want it. With the morning turn of the key and a cold motor, AFR bounces around up over 14.5. As the motor warms the AFR drops to bouncily settle around 12.
I've raised rpm for a cold motor as well as cold idle enrichment. Nothing works at all. It's gotta be in the fuel map. My fuel map is extremely "plateauish" whereas an unofficial expert, friend of a friend, says he doesn't even know how my cars runs with the map after I emailed him the .bin to inspect. (unofficial expert tunes at a local dyno shop when he's not flying airliners) no time for me without buku $$$
Any help and or suggestions would be great!
The bin is the original from calum with a mild street tune. A bin I acquired here on the forum that has a 2 step also has this plateau of a fuel map.
