Gtech Comp RR - Anyone familiar?

[Tommy]

I recently bought a Gtech RR and wanted to run the LS with it. Well the unit uses alternator wine to gauge RPM and it seems the LS alt is so quiet the damned thing draws a blank. I can't get a good RPM signature. I've tried a lot of suggestions. Anyone else know some tricks on our car for this? :Bang :Bang :Bang argue2 :soapbox:

I use a G-Tech Pro Competition model (almost 4yrs now) - which is now called the the RR model.

I simply tapped into the 12v running to the cigarette lighter.

I've tried the 12v at the lighter and the 12v accessory outlet. I'm contemplating an extension wired straight to the alternator. I get the feeling they put filters in to kill the radio noise I need!
