You need proper afr
You need proper timing
You need to pay attention to the cells AROUND both those areas too, they affect it
You need to do idle valve test to determine iacv range
You need to tune CL idle control settings, PID, and dashpots
You need proper AIT compensation
You need proper EGO correction settings
There's probably more I'm forgetting
A lot of this stuff gets overlooked
You're right about that, but I think most of that's covered. I've attached my tune a few posts earlier.
rpm is stable enough in my opinion but it's the vibration I want to get rid of...
I will post a log when idling, maybe you guys notice something wrong.
