Default Idle tip in accel fuel

How much accel fuel does your engine require to ensure a crisp throttle response when stabbing the accelerator at idle?

This is not a question specific to any particular after market ECU - answers in percentage added to base pulse width or ms added pulse width.

Anyone else? Specifically interested in idle how much fuel your engine needs for a crisp throttle response at idle. Getting instant, crisp response when stabbing the throttle from idle always seems to have been the toughest transition to get just right.

if you can set the enrichment to trigger on TPS *or* MAP increases, it may help.

I have an an additional 1.0ms TPS triggered enrichment, and a 45% variable TPS enrichment (depends on speed of throttle movement). Can't remember the duration I have set off hand. I also have a temp dependent one, 1 sec duration, but can't remember the % pulse width increase for that one! Tip in is good (no hesitation), but I feel it could be better, which is why I am interested to see if we can manage to determine a reasonable ball park figure for others to start from, independent of the ECU of choice.
