My OBD software can do a drag strip measurement like a dyno, just for fun i'm willing to give it a go and see what kind of results it produces (it does have some nice graphs that i can upload in the forum).

It requires me to enter a few details about the car like tire measurements and weight. Unfortunately, it also requires me to enter the "Final Drive Ratio".

Any ideas what this number is for the GranSport? (all stock, engine, tires, rims, etc).

I'm using "PCMSCAN" as my OBD II software.
