I've got a 86 SC with a 89 SMEC setup running a flash-able boost button SMEC I've been picking away at adjusting my tune and have it close to where i want it...except for cold start, as in when it hasn't been ran in a day or so. First initial start is dirty rich. Car just sits and chuggs out black smoke and sounds like its running on 2 cyl for the first 30-45 seconds and clears up shortly after that and runs smooth. AFR is 10.0 during that time and once it clears up is hovers around 11.5-12.0 at idle. What numbers should i see on my AFR once the engine is warm at idle?
I'm sure this info is on here somewhere so if some could lead in the right direction for what to adjust that would be awesome!
