How do I data log? I'm a complete newb at this. I have a Xcal 2 and a laptop with the software on it. I'm still getting a small intermittent hiccup at cruise in the lower RPM's.

I would like to datalog stuff like maf transfer and voltage, TPS voltage, front 02's, fuel pressure at cruise, FRPS, cam and crank sensors, and the coil packs.

I also have another question concerning a user parameter in the Xcal. It says I'm able to lower and raise the global spark it certain rpm ranges. I feel the hiccup might be helped with a little more timing in the 2-4k range due to my heads having no swirl damns and not burning the air fuel mixture well enough in part throttle cruising conditions. How will this effect my WOT tune?
