First runs on the Gtech..

So the GTech can give rpm just from being plugged into an electrical source on the truck? Can it time roll ons from say 70-120mph? 0-60 isn't practical.

Should also note that the Rock Falls track is a **** hole and a Gtech is actually probably more accurate then running on that track.

Did not know that. Good to know.

Also, I believe yes, the GTech can do 70-120 rolls, etc.... Just gotta play with it some more. Right now waiting for my homemade bolt-in frost plugs to set (black silicone sealant. ) and then put the twins back on and run it. My new IP should be here next Monday.

It gets pulses from the alternator through the cigarette lighter. Works fine on my 95, not so much on my 89. Pretty sure it has to do with the external voltage regulator.

It can time 0-4000ft (for some reason) before it times out, so pretty sure you could get up to 120mph in 8/10 of a mile.

This is all their cheapo version, the others can do more, including data log.
