Re: What do you log when you drag race? With Autotap, Ii log the minimum # of parameters to get highest resolution in a drag situation.
RPMs
MPH (optional, found this helpful sometimes)
Timing OR Knock Retard (I can derive one from the other)
ONE O2 Bank (the one that reads the lowest)
Inj PW (1 or 2, not both)
That's four or 5 parameters, and I get the most data. I'm trying to determine if I'm detonating and whether it's possible I'm running lean or not (or rich) AND if my tranny may be slipping or some other tranny issue (the MPH part).
Also, I'm trying to decide if I can bump up my timing.

Re: What do you log when you drag race? The reason I don't log LTFT's on the track, if they aren't in line, it's pretty much too late to do anything about them. I don't try to tune LTRM situations on the dyno or at the track... I try to work out what I can live with beore I get to either of those two places. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
