Hmm, yeah I would check connections and such. I have never had any luck with Prosport gauges. That was a while back though when they were first becoming big so their quality may have jumped since then.

Does it need to be calibrated like the LC1?

 

i calibrated it like the install thing says, but thats not the problem. changed all the power ground sources didnt fix it. im at a lose right now.

 

did you install the led on the black wire?

 

what led? i dont have a lc-1 or mtx, i have the prosport setup.

 

i dont even know what that means.

 

What kind of o2 sensor do they use? Bosch?

 

yea its a bosch.

Hmm that's odd. Only things I can think of (if wiring is good) is that the calibration got screwed up, or the sensor went bad, how far from the turbo outlet do you have the sensor?

 

stock location on the greddy kit. about 3/4 of the way down the stock downpipe. estamtied about a foot and a half maybe.
