Getting odd rpm flare when entering closed loop during idle
When I first start the car it idles fine in open loop then when it warms up and enters closed loop upon entering the rpms flare up about 200 rpm and then everythng is fine. What is causing this? 730ecm...

Sounds like the open loop AFR is off. So stall saver is implimented for a few moments. Need to experiment a little on the cold AFRs, IMO.
