Megasquirt acceleration enrichments
went out for a blast this afternoon and noticed that when i accelerate hard the AFR gauge on my megatune screen just goes straight into the lean area
of the gauge sometimes maxing out at 20:1, is this down to the acceleration enrichments how do i go about adjusting them.

Are you sure your fueling is correct, and i'd only find out once and never make itthat lean agin, even if it means not driving, it's a
recipe for disaster.
Just drive nice and slow with low throttles for a bit, see how that fairs, make sure the fueling os ok for light throttle, then when they're
sorted move on to the AE wizard.
What load method are you using?

I use MAP related enrichment with an engine that has MAP for load control.
I tried throttle rate as the input for accel enrichment but it was much worse.
My experience with throttle body injection (on a siamesed inlet ported engine) that has large amounts of wall wetting is that you need a high value of
enrichment for a very short time. A low value for a long time does not fix the initial transient enleanment and then makes it very rich afterwards.
