Idle spark

[krusty]

Also keep in mind that the run spark table just off idle is probably working with drive away enrichment or power enrichment. Fuelling is different through those transitions so spark needs to go with that. If it's a stock cam and even though it's intercooled (???) there's not much boost happening there so you may find the standard run spark values quite accurate

No cooler yet.

I wouldnt think that PE is enabled as its set to > 40% ish throttle and is drive away enrichment the same thing ???

I think krusty is talking about transients as in AE (Accel enrich).

Yeah, there's a few progressions of enrichment so even if you give it 5% tps it will enrichen slightly but much much less than PE. Timing is needed where cylinder efficiency is poor so at low rpm the engine is poor for being productive usually so a lot of spark the minute you ask it to do something is needed to wake it up. Top end with rpm and cylinder flow on board therefore needs substantially less timing in a boosted car usually
