Hey gentlemen, sub thread for the vems tuning.
Basic VE mapping done.
Road testing yesterday and shifting AFR's are pretty squirrelly (Greg, substitute any obtrusive marsupial here).
Ok, so I didn't address AE yet.
I had a couple of shifts with mid-load RPM's that caused a fuel starvation and the car shut off on the interstate
So looking at log, there is no tip in seen, just lean. My question is relative to the raise in enrichment and the answer is probably more trial and error, but Vems has an Acceleration Enrichment gauge. Currently the highest number I've seen is 0.1.
What number is more appropriate? Or what guidelines for AFR/Lambda at that initial throttle poke?
There's also an issue, which overlaps, of letting clutch out on manual tranny and rpms going up on the back end of a shift.
Vems has a separate category for throttle v. acceleration enrichment but same concept as above in relative terms,
Dave
