I drive a 335I sedan manual sport and have put into the G-tech a weight of 3600 for car 200lbs for me and 100lbs for gas total 3900. Is this close to what you guys have been putting into you computer. And with the sport i put in a pitch factor of 1.5.
My runs have been around 5.15 0-60 best so far of 5.14 and one totally crazy run 1/4mile12.56nooooowayyyyy I figure its fall and i must have had a bigg wind behind me anyway the other times have been pretty consistent.
I'd like to be a accurate as possible and I know you guys out there do to.:thumbup:

you dont need to do all that unless you want to roughly find out what your h.p. is. G-tech will give you correct acceleration times(give or take a tenth) without any extra info.

Skip the weight, but make sure the unit is level, your road is level and free of bumps. The gtech pro can be very accurate or it can be way off, so best to do back to back runs going both ways on the same road to verify. To say a car runs 12.8 for example it should be able to do that all day long, not just get one lucky run.
