I can't seem to get the acell enrichment to slow down enough, it's popping and bucking past 50% acell. During moderate acell it's fine up to 50% TPS. If I stab it quick past 50%, it pops and bucks again. i've tried to reduce the enrichment and also increasesd the range bins for both map and TPS (running about 60% map / 40% tps balance between the two). this is on an 8 cyl mutiport boosted application. I've run this same setup before and had no problems until I upgraded the firmware and Megature to newer versions (the megature is 2.25 I believe)
On thing i've noticed is it doesn't take much to send the red bar all the way to the top of the TPS sliding graph. I can't seem to figure out how to make it less sensitive.

Re: Can't slow down accel enrich
Ah,
Popping and bucking are typically symptoms of not enough accel enrichment, not too much. Too much accel enrichment would make the engine sluggish - and make a lot of black smoke out the exhaust!

That makes sense, I'll give ita try. I should know this by now, I feel stupid.
