quick question for idle control
When guys swap to auto like a glide or th400, how do they keep the idle good with dbw? I currently have a manual valve body 4l60 and it wants to die when I put it in gear. It's got me to the point of going to full auto.

I don't really know what your are talking about, but you would need a tune. The VCM is expecting data from the transmission, which should be a 4l60E. If you don't have that tranny there, the VCM is obviously looking for a information that it will never get. You need to have the auto trans disabled as in a manual trans and then play with your idle controls until it will hold but it will never be perfect.

Typically in the tune, the in gear idle airflow is slightly higher. About 2 g/sec.
This should be easy to tweak as the high stall converter should place very little load on the engine when in gear.
I'm running a manual calibration in my Nova with a TH400 and it has no issue at all going in and out of gear.
