Idle Surge

[Camaro9969]

Been working on my tune got it a lot better idling smooth but after a short drive it surges a lot. Sometimes nothing but others awful. I do not get why maybe someone can tell me on here. I got some help and going to adjust the cracker and follower a little but figured i would throw this up here also.
The Tune and The log from driving today.........

You need to log the idle stuff. Cracker, follower, stit, idle desired airflow, IAC, etc. Then you can figure out what is going on. Cracker is just rolling idle. Follower "follows" TPS. The follower you want to adjust to decay out just when the car reaches idle RPM. Have you done RAF?

There are some good treads on here about idle stuff. I'll post the config and a log that I used on my camaro.

Awesome thanks i'll do this today.......i noticed my ve in the lower cells like 400-800rpm and lower kpa's were not smooth so maybe the jumps were making it surge i'll try both of these and post a log.
