Has anyone came across a parameter for enrichment after dfco or anything similar on the gen 3 gm pcms? Drives me nuts to hit dfco thinking im saving fuel and get the .88-.93 lambda for a few seconds after the engine fires back up.

its pretty normal to need some enrichment at the exit point or you will feel it. going immediately back to stoich results in a hiccup
but if you have 2 seconds of no fuel then 2 seconds of like 10% more fuel, well......do the math yourself
I had thought about the transition back to stoich but i do like a experiment. I figure it may result in a small count of misfires.
