XCAL2 DataLogging acceptable numbers? what 2 watch?
Ok, I just got my XCAL2, and got it working. (a feat in itself). Now that I can datalog, what in the heck should I be watching?
I've chosen some of the things I thought, but they are mrerely graphed out to number ranges. I don't have a clue as to what acceptable number ranges are. So if any of you have a sec, could you give a list of what you like to watch and what number ranges is ideal and beyond acceptable for what you are watching?
Thanks a lot.

Sorry.
MAF counts depend on what handheld you are using. If the Xcal2, I think the "pegged" value is something like 1240 counts - you should verify this. This value tells you if the mass air meter is within range.
Tranny temp - I like to keep mine below 180.
Coolant temp - your preference. I like mine at 180.
IAT1 and 2 - there's a relationship between the two that you will have to do some reading of other posts to understand this fully. But you want both as low as you can get them. This tells you the temp of the air entering the engine and the temp of the air after the blower.
Short term fuel - log and send the graph to your tuner. It tells him how "spot on" your street tune is. Basically, it shows how hard the computer is having to work to keep your A/F ratio correct.
