This is my next accessory purchase: An Accelerometer.
With this tool, one can measure their vehicles:
-Braking Force
-Cornering
-G-Force
-Horsepower
-0-60 Second Acceleration
-1/4 Mile Time / Speed

I used to have a first generation G-Tech Pro Accelerometer, but I didn’t like having to have it plugged into the cigarette lighter for power, and I didn’t want to hard wire it in.
I like the big 3″ wide x 0.5″ tall backlit LCD display.
This accelerometer will run for a full year on three AAA batteries.
No need to wire it in. No wires to mess with.
I can’t wait to try it out!

I’ll post pics when I find a good place to mount it.
I don’t want to use the windshield mount if I don’t have to.
