The cold start enrichment is done in phases ...
1) Start phase .. mucho fuel for 5 to 10 revs of the engine ..
2) Post start enrichment lasting a few tens of seconds or so
3) Warmup enrichment .. until engine is at running temp ..
Warmup usually has two tables .. one based on engine temp,
and one based on speed, MAP ... the final number is a
multiplicand of the two ...
Eng. temp .. more enrichment at lower engine temps ..
Speed, MAP .. less enrichment at higher speeds and MAPS ..
Hope this helps ..
