    Default Log fuel pressure with Autometer sensor?

    I know I seen someone logging fuel pressure from using the EGR or oil pressure connector, but I cant find it. I am installing a Autometer fuel pressure gauge (electrical sending unit) and want to wire everything up so I can also log it via EFILive.

    Thanks,
    Sam

    Perfect, Thanks RHS . How do these Autometer sending units stack up in the accuracy department?

    good question! I guess just bring 5 different brands fuel pressure meters, hook them all up, see how they compare. If they agree, great. if they don't, back to the drawing board.

    10-4. I didnt read through the whole thread you linked me (8 pages), but I looked at the .pdf and I do not have a EGR or the wiring connector in my harness (2005 pcm.)

    Any other options other than connecting it directly to my V2 unit?

    You can do what I did and add the pin to the PCM connector or
    you can strip the very end of a wire and push it into the pin slot.
    I did this before getting the pin and it worked.

    Or you could use a 5v regulator.

    Thats what I'll end up doing. Anyone know what size the terminals are for the PCM? I assume they're weatherpack terminals..

    Is anyone running this with the gauge actually installed? To be clear, I want to have the gauge mounted in my car and also be able to scan via EFILive. I havent had time to figure out the wiring yet to see if that is going to be a problem..

    These are what you need for the LS1 PCM.

    You can probably split the signal wire to both Flashscan and the gauge.

    Thanks for the link, once again exactly what I need.

    I was thinking I could split the signal wire as well but I am not sure. Does anyone know for sure?
