I have played with this for a long while and cannot get the idle to stablize. I have tried everything that I have read about. If someone could review my datalog and my tune, please offer assistance. It is annoying to get a swinging rpm idle all the time Whether I move the base idle airflow up or down makes no difference along with various afr's and timing. What am I missing?
this is the closest I can get it. IT will stay steady around 850rpm and then start swinging +/- 50 or so rpm before stabilizing again. Also when I start the car, there is high rpm flare-up, like 2k rpm before it comes back down to 850ish idle.
