[Diy_efi] acceleration enrichment? retard or advance ignition timing?

Guys I'm confused...when you accelerate are you suppose to temporarily
advance or retard the timing a bit more than the basic advance? One guy
tells me I should retard timing because that's how the old vacuum advance
works and another tells me I should advance it period. What's the reason
behind the temporary advance or retard? How is this done? Is there a time
duration for the temporary enrichment? Will it suffice to just read the
throttle position sensor to know that the engine is accelerating and add a
static enrichment? Any help would be much appreciated.

Thanks In Advance,
Toffer
