Ok here's a new problem I encountered last night while cruising the street scene. I noticed when I let off the throttle the A/F ratio stays around 12.6 until my speed drops below 50mph and then the A/F goes back to normal. Anybody have any idea why it's doing this?

Correction - I should rename this thread "Decel A/F too low" instead of too high. Any help is greatly appreciated.

I take it I'm the only one with this problem? I still haven't figured it out yet.

Are you running large injectors? I have 4 x 85lb injectors (same as 8 x 42lb) and on hard decel, it's at the min pulsewidth and can't run any leaner than ~12:1. But, fortunately, I have the option to cut off fuel completely on decel to help save fuel.

I'm running 30lb injectors. Constant is set at 33lbs

Decel Enlean Vs differential MAP
Decel Enlean vs differential TPS

Does anyone know the S_AUJP v4 translation to these 2 tables?
