Idle for H/C/I 404. I have a big cam on my 404 and a fast 102 intake with 102mm tb and intake tract. I am running without a MAF sensor.
I am having some issues with my idle still. I have idle set to 950, i initially tuned off of wideband, but i reenabled STFTs and did some fine tweaks off of them. It appears that the nb o2s are responding well.
It idles but it'll almost die sometimes, especially when cold. Ive done a few cold idle scans and corrected raf.
I noticed that my desired airflow and dynamic airflow don't really match up.
My steps are like 170ish. Should I adjust my set screw to get the steps down?
63 kpa map, spark stays steady at 25ish.
I dont understand how to tweak iac vs effective area, do i need to play with this?
