Hey Folks, what data do I need to log to be able to generate a HP/TQ curve in DLL? Do I just need vehicle speed?

All you need is RPM and time. Make sure your gear ratios, vehicle weight, wheel/tire size, frontal area and drag coefficient are correct.

I did some searching here. I found several threads referencing 0.39 Cd, and I also that thread that has the aerodynamics article on the Evo/STi/Mazdaspeed.

I have seen 0.36 as the most quoted number.
