Default Accel enrichment

If I let off the throttle alittle and then press the throttle pedal back down some I get a lean spike briefly running in closed loop SD. I have looked in EFILive and haven't found anything for this. My buddy has HPT and he found this description and I think this describes it good.

Acceleration enrichment is a simple throttle transient fuel compensation calculation. Using the change in TPS (TPS delta) as the primary factor, the pcm calculates an enrichment fraction. The enrichment fraction is then added to the current commanded fuel.

Is there anything like this in EFILive?
