Heres what I am thinking. The gauge obviously reads up to 2 bar of boost. The sensor is definitely a GM part. The question is:
Why can't you use this sensor and just split off the wiring?
Beats paying $60-70 from gmpartsdirect + the harness/connector. Not to mention I already have it installed in the car. Running one sensor should clean things up a bit, as well as saving $$$.
Let me know if anyone has done it or if you foresee any problems doing it this way.
I think you can, if no1 has tried it I will give it a shot and report back.
As you may well know, there are mechanical and electronic boost gauges; I am running the electronic. There is a MAP sensor in the engine bay, and wire(s) that run to the boost gauge. purely, electronic.
the MAP sensor that controls the gauge is, at least in appearance, identical to the ones I have had in my GM cars and the ones shown in pictures(see link above). the only question is; is it a 3BAR?
I suppose I will find out tonight when I compare to the #s on the website. That is assuming that it is an authentic GM part, which it probably isn't. Perhaps it uses the same/similar markings if I am lucky.

May be. Most boost sensors take a 5v input and ground, and output a 0-5v signal. At least that's how the Greddy sensors work .
It would take like 5 minutes with a multimeter and a Mity-Vac to determine what it outputs. I know the pressure/voltage chart for the 3-bar sensor is out there somewhere.
Also, if it looks like the GM sensor, it very likely is the sensor. I've never seen one, so I can't wager a guess .

I agree it should be easy to tell, if I had a battery in my car. I was just wondering if anyone had an idea or has done it before. I hope it has some distinctive markings that will help me out. I am pretty sure that it is. How else would it read up to 2bar boost?
