Then when you get in different weather conditions your wide band will tell you if you need to lean or fatten it up.

x2! I'm brand spankin' new to EFI, just off my 3rd weekend out. Even if someone runs the same combination as you, there can be something different in either the data collection (type or location of the sensor) or other variables that make things radically different. Ultimately, you have to listen to what the car is telling you on the race track to determine what A/F ratio works best for YOUR setup. Took me til 1st round of eliminations this weekend to figure that out! LOL In the ballpark now, though. I still have a TON of learning to do. One of my issues right now is that I have no basis for what the numbers mean relative to each other. Is half a point in A/F ratio a lot, .25, or is a full point a big swing? Along the same line, I'll need to figure out how much change a single number or single percentage point on the fuel table really is.
