It measure power being put to the road in a real situation, as far as I know you still have to do a quarter mile to get a proper reading from it, so if you shortened the diff, and do a quicker 1/4 mile, you probably got more power to the road and that's what it reads. If I could find my user manual I would post what it says about it all.Dazza.

It was pretty hot when I did tha run, 30 degrees and when it cooled down the engine was hotter, so it made no difference.Dazza.

Diff ratios, wheel sizes, gear ratios have zero input to the G-Tech's calculations. It uses the force of accelleration measured over time - simple, no more no less. If you enter correct weight it can also calculate power. As has been said, it is a true or "real time" measurement of the force/power applied to the wheels and the power readings will be lower than what a dyno will show because it takes into account ALL outside variables acting upon the vehicle at the time of the "run". If you're skeptical (or can't spell), go learn some physics or get a technical buletin from G-Tech to understand how it's done. And, as for accuracy it is more in the order of 1% not 10%. BUT - like any instrument it is only as good as the operator and errors can easily creep in if not used exactly according to the "book". What turbo6man said is basically what it says in the manual, considering the accuracy of the timing of the G-Tech, I believe the power function will be accurate also, the problem is backing this up on a dyno, since there is bigger variances there.Dazza.

Seems a lot more refined at least in design than the older 1994 version which is mostly available on ebay.

Mines the older black one, looks prehistoric compared to that one, but I figured it was pointless to spend so much money on the new fancy one when I only want it to mess around with 0-100 and 1/4 mile times.Dazza.
