Finally got around to tuning my 3800SC in my Fiero.
At idle, I've noticed it running lean at startup but slightly rich after everything is heat soaked. Was hoping to use IATs to account for that. The only table I see using IAT is for spark timing. I can't imagine GM using IAT sensors and not adjusting for air density. Is that a table that's just not available?
I've started modifying the startup AFR correction table to add fuel at lower temps, but I'm not getting the results I would expect quite yet. Has anyone else tackled this yet?
