    PLX Setup/Issues

    Hi All,

    Looking for some help setting up my PLX to work my MaptuneX logger and PLX DM6 gauge.

    I wired it in exactly as the directions say, using the same power and grounds that powered my Innovate MTX-L and Innovate Boost gauges in the past which never had any issues.

    The problem is, I cant get the gauge to power up. This has me wondering if I bought a bad gauge (from amazon, PLX was main unit was purchased from GH) or whether the main PLX box is shot. I even direct wired it to the battery and got nothing.

    Is there something I am missing?

    The only reason I want to run a gauge instead of a dash pac is so that I can log and monitor my AFR at the same time.

    Thank you,
    Ryan

    I just installed a PLX afr & egt sensors and the only issue I had was that the afr sensor has a built in 8v converter so it expects any other sensor you install to be daisy chained off of that. If you install another sensor, not daisy chained off afr, then you must install an 8v converter. I didn't want to deal with toggle between sensors so I used two DM6 gauges and missed this 8v converter install because I didn't take the time to follow instructions...lol. Without the converter the gauge attempts to power up then fades out to black...might that be what you see? Your just setting up their afr sensor so I doubt it. Only other thing I can think of is the termination jumper...it missing? I had stumbled upon a hard reset method because once I installed that 8vv converter it still would not power up...hard reset cured it. I can't recall but it's a sequence of 2 or 3 buttons on the DM6 you have to hold in. Might be worth a shot. I think that hard reset is undocumented and might have seen it in their faq section on their site.

    I am only using the sensor that came with it, so that shouldn't be my issue. As for the termination jumper, I thought it might be an issue myself so I removed it and placed it back in with no change sadly. I will look into the hard reset you mentioned, thank you for the heads up on that. I have submitted a ticket on their site to see if there is anything else.

    Polarity correct? I know that's key on the PLX

    If you mean positive and negative, I can assure you it is. The gauge is plugged into the TX terminal on the module which is also correct.

    Hold all 3 buttons in while it's initialing is how you reset the DM6 to factory defaults. DId you test for voltage on the sensor plug end? Even when I goofed up missing that 8v converter I mentioned the gauge still did flash something then faded out and flashed red.
