"G-TECH is designed to make a professional test driver out of anybody. All you have to do is plug it in a cigarette lighter, mount it to the windshield and start accelerating. G-TECH/Pro does the rest automatically and displays the results. It's a great way to get performance and safety information about you car."

"All the measurements are performed automatically. All you have to do is push the button indicating to G-TECH/Pro that you are ready and then G-TECH/Pro will zero-out and display -GO-. Then simply start accelerating. G-TECH/Pro will know your speed and distance at any given moment and stop the measurement at 60 MPH or 1/4 mile point."

Measures:

- 0 to 60 MPH time
- 1/4 mile elapsed time (E.T.)
- 1/4 mile trap speed
- Instantaneous lateral acceleration (G s)
- Sustained lateral acceleration (G s)
- 60 MPH braking distance
- Instantaneous braking Gs
- Sustained braking Gs
- Horsepower

got info on the net. dont have instructions, but i downloaded the manual from the gtech website.barely used.....good for tuning/when your adding new parts or getting your driving skills downpacked. asking $40 or trade for?

 

im not sure how it works by just plugging it into the lighter.

 

it just gets power from it...its all done by gyros and little sensors and chips inside of it...its quite simple actually

 

yup.......TTT
