Celica is up and running today. It's running super rich especially at idle. Any idea what may be the problem? My afr guage is buried at 10 and its burning black soot out the tail pipe.. It drives pretty good but it's jumpy when I let off the accelerator. I have a apexi neo safc installed. any links on how to set this up?

It SHOULD be doing nothing at idle, AFC's are made for ONLY open loop full throttle kind of operation, not to control fuel at idle and low throttle. The computer will adjust fuel trims accordingly and wipe out whatever the AFC is trying to do in closed loop. If your settings are affecting idle then something is set wrong, you need to get back to basics.
