Hi guys, I have a choppy hydraulic cam, set up for a target idle speed of 750 rpms, which ends up being around 800 warm, (when the car is behaving and not creeping over this speed). I based my bin on a 1989 corvette, which had a hot target idle of 700 rpms. Should I bump the decel enleanment minimum speed up 50 or 100 rpms to compensate for my higher idle speed? If my idle decided to creep up to 850-900 rpms after releasing the throttle, it would meet the no load, 900 rpm minimum for current decel enleanment, and I'd think this would wreak havoc with idle BLM's.

Try doing what I posted in your other thread first.

This also assumes that your TB is in good mechanical order and clean andyour throtle cable is not making it stick or bind.(or tb blades/bushings worn or otherwise impaired)

Also includes a properly set IAC vavle and a properly set TPS sensor(depending on ecm)..

I think trying the decel enlean that low may very well push you to/or very near stalling and you would have a large rpm jump when it comes off of decel enlean. I experienced that when I was moving my decel enlean settings around to see what effects it had.
