Idle issues

[Reddragon]

idle is the most difficult thing to get right for the beginner. the big things to look for are the AFR and timing at idle. if the AFR is swinging the idle will never get steady.

please post a datalog of the car starting and idling along with a copy of your current tune file.

for help beyond just advice check out my services page link in my signature.

I will need to see a datalog of the issue.

I assume no tuning has been done, if that's the case then you first have to achieve a semi stable idle. Shoot for 1k rpm in park for now so it does not die going into gear
