I recently purchased a autoenginuity obd-II scanner that came with this program called Speedtracer. It lets me compute hp/tq relative to engine rpm, braking distance, and acceleration times after putting in car specs and temp information

however, it requires a whole load of car specs that I can't seem to figure out:

category: gear ratio variables
-working gear, supposedly the gear ratio of the gear you want to calibrate in (1.392:1, preloaded 2k2 manual spec), i believe 2k1 manual is 1.308?
-rear end ratio, have no idea what this is (3.812:1 preloaded 2k2 manual spec)

gear ratio can be computed by entering tire specs and driving around in the gear you want, but it keeps coming out to 5.27 (5.3063 preloaded 2k2 maxima manual)

drag coefficient? listed as .31 for 2k2 maxima

if your wondering why i'm listing 2k2 specs is because the software doesn't have anything below 2k2 manual for maximas so I have to enter it manually. I suspect the software is off cause the listed curb weight for a 2k2 spec-v is 3650 lbs
