: Gtech Pro Competition

I am trying my Gtech Pro Competition (firmware 3.0) on the car's front lighter socket, but cannot get any RPM signal. Did anyone had this problem? :banghead:
Did you wire it differently?

The voltage at the cigarette lighter may be too filtered for the G-Tech. To get around it, run a fused line straight off the alternator. The G-tech uses the AC oscillations in voltage from the alternator to determine the RPM. Remember to calibrate the RPM reading for the V as each car is slightly different.

Another shade-tree trick is to turn on the headlights to make the alternator work harder, producing a more "visible" signal.

I got it to register (a little sketchy but it logged my times) by holding it near the tach when doing it. Ask wild for some more tricks, he was the one who mentioned that, and I did eventually get it working. RPM was not exact, but you're talking about a device inside a car that has (arguably) very good sound insulation, and a rumbly cam.

Forgot another one - turn on the rear window defroster in addition to the headlights to put a bigger load on the alternator.

Cal has it right. I managed to get a pretty good RPM signal by mounting the Gtech to the instrument cluster on the right hand side. Having the headlights on seems to help as well. It wasn't perfect, but good enough to get some consistent readings.

Good luck. (Dealer says car is done, I'll pick her up in the morning).

I believe the goal is to make a user friendly, plug and play device that doesn't require any hardwiring. I've made it work quite well by doing as outlined above (at idle, the RPM's misread but anything over about 2K looks correct). Kind of a cool gadget in that all you have to do is place the suction cup mount where you want it, plug it into the cigarette lighter, enter a couple of numbers and PLAY!

A classic South Park episode, almost as funny as "Good Times with Weapons."


Back on topic, Silver Baron - did you get the Pro Comp to work? If so, results?

What ever happened to the send the Pro Comp to a friend and so on and so on idea?
