I bought one and it was within 1 tenth of a second of the track clock. Also does 0 to 60, 60 to 0, hp and side g-force.

you must have traction!!! ANY wheel spin at all, and your times will be way off. if you get good traction, 1/10th of a second, is just right. it's reliable enough to know if the new parts you put on made a horsepower differance.

How does wheel spin throw off the G-Tech when is is baised off accelermeter technology? I think it is more sensitive to unlevel road conditions and vehicle body lift.
I have one, and it is fun to play with. It may be useful for comparing modifications? The difficult part is actually using it in the 1/4 mile ET mode (on the street) as you need a straight, flat road where you can run a full 1/4 mile, plus a slow down area, without encountering traffic. Most performance cars will be going over 90+ MPH after 1/4 mile acceleration so it is not too safe to use this mode on the street. The 0-60 MPH mode is much more useful on the street Also the MAX cornering and acceleration/decelleration G-Force measurements are fun to play with. |

G-Tech
I just acquired 1 and went out testing it, and if you dont have traction and are just spinning it shows in et, compared to a run with traction. The G-tech seems to be pretty accurate even if it isnt dead on its a good tuning tool.

I just bought one of these and it rocks!
Think about it. It's the only thing that measures changes on the car. Actual changes in performance. Engine dyno's ignore the drivetrain. Chassis dynosmeasure how well your cars tires can turn a drum, not what your car is actually doing. Especially with all the BS in the magazines these days. I read in Hot ROD where they admitted that alot of the build up articles they have done in the past BS. Why? THrow in a cam and intake, and sure, you get big # on an engine dyno. Put the engine back in the car, and the loss of low end torque has tuned it into a dog. Slower than before! |

I hear you on the engine Dyno numbers shown in magazines, you need to look closely at the RPm range they are measured at. I think in a recent Hot Rod, they had a "killer" small block, the sidebar with the dyno numbers started at 5,000 RPM and went up past 7,000 RPM. Not exactly a "street" engine RPM range
