actually its about 11.0 to 1 or so. The graph is real choppy though so its hard to tell

sure, send it. cobra99vert@aol.com

my charts were always a little choppy. i would have liked to see a nice smooth a/f ratio but it was more like a rickterscale graph varing about 1 point. so when i say i was running 11.5-1 a/f ratio that means it was between 11 and 12-1 and i was averaging. also i was always a leaner in 1st gear, less lean in 2nd and the richest in 3rd. the best i could do was about 12-1 in 1st, 11.5-1 in 2nd and 11-1 in 3rd. never did figure that one out.

here is a screen pic of one of my runs, prety sure this was a nitrous run and the diferieng a/f ratios are alot worse when i used the nitrous. without the nitrous the graph looked about the same but 1st was a little richer and 3rd was a little leaner.

that pretty much answers my questions about the choppy screen. Mine looks the same. So you just take an average of the chop and go by that?
