A Part 2? Absolutely.

There are several ideas that we didn't cover in the first post that IMHO need to be covered when discussing part throttle fuel tuning.

1) I never discussed idle speed. However, I always adjust my idle speed before even beginning to tune the fuel curves.
2) I never discussed Pump Shot (aka Accelerator Pump Enrichment).
3) The affects of Temperature on the VE curves.
4) Open loop changes to the Air/Fuel Ratio (coolant and MAP).

I'll address these topics in subsequent posts.

Just wanted to say that I haven't forgotten about this post. Been very busy this week. If anyone wants to share feel free. I'll get around to posting my understanding within a couple of days.

Maybe one day ... but not anytime soon. Too much going on in life at the moment.
