For those of you that data log at the track using your predator, which parameters do you record? Or which PIDs? What should I be looking for? How do you adjust your tune based on what you see?

Going to the track tomorrow and any info would be helpful. Thanks.

 

rpm, vehicle speed, load, gear, intake air temp, timing advance are my top picks.

Dustin why don't you ask George? He was a great help to me.

Yeah I usually pick the same as Dan when I data log. I still havent figured out how to put it all on my laptop yet. I usually compair runs and see what is different in intake temps and timing vs. my time slips and if i trapped at a lower speed. Plus it tells me how Im leaving the line.

 

Looks like I'm losing timing right after my 60' (which was a 1.75 on this run). See how the speed goes up, but then the timing (spark) takes a nose dive.
