Hey guys. Getting the car dialed in. After the car is warm sometimes the idle will bounce between 800-1100. When i drive then put the car in nutrial, it idels great at 900. when i come to a stop sometimes it will fluxuate. But sometimes i can pull up to a light, and bam it idle's great at 900. What should i check out.?

thx

Desired Air flow.
You can log ect vs rafig from cold startup in a map and add to your desired air table. Do a search for "idle transition" you will see all the info there.
You might also need to tweak spark/idle under and overshoot timing adjustment downwards.

The BIDI controls are good for finding the spark and AFR your engine likes for idle. Key to idle is getting the B4307 table dialed in.
