    B1S2 for Fuel Pressure - '97 GTP

    If I purchased a psi sensor from Innovate (http://www.innovatemotorsports.com/x...at=265&page=1), could I hook this up to B1S'2' and then read/monitor with HPTuners?

    I'd guess the sensor would work because it's 0-5 volts that can be a custom PID in HPTuners but I'm not sure if B1S2 is capable of that. I'd have to get switched 12 volt to the sensor is about it. I'm not sure because I have a "dummy" plugged into B1S2 because I removed the Cat (before I had HPTuners).

    Thanks for the help and advice. I would like to also add a LM-1 via the EGR.

    As far as I know, it won't work. The O2 sensor is a 0-1 volt sensor, putting a 5 volt sensor on this wire should not work.

    You could use the EGR for this, but as you stated you want to use that for the LM-1. I take it you do not have the pro version of the HPT hardware?

    Not sure how to tell you to go about doing it, sorry...

    Bump for more comments and thanks to Eddie.

    I do not have the Pro HPTuners interface. And that may be my best bet. Or just run a regular gauge for the fuel pressure and EGR for wideband.

    Any ideas fellas?

    I have a fuel pressure and oil pressure gauge mounted in the console that works good. I'm not sure what kind of car you have, but here's a pic of the gauges in my 98 GTP(I have sinced centered the fuel pressure gauge )

    I have a '97 GTP. I have a oil, trans temp and boost on the 3-guage driver pillar. I have an ICCU currently hanging where the ash tray used to be. If I pull that out, like I plan, then mounting like you have them would be a great idea.

    I think, all I need would be fuel pressure and then wideband via EGR to monitor with HPTuners.

    Thanks for the pic.
