    Thankyou.
    Connect 1st PLX to AD1+ signal and AD1- ground.
    Connect 2nd PLX to AD2+ signal and AD2- ground.
    Log the pids EXT.AD1 and EXT.AD2.
    Select the calc pids CALC.AFR_PLX1/2 and CALC.BEN_PLX1/2.

    In FVS2 device settings, checkmark the box to always include External Analog Pids.

    Thanks Joe, think it worked out ok, although more fumbling than knowing what I'm doing

    I had to remove some odd pids that it did'nt like, maybe that's because I still have the HPtuners 2bar custom tune loaded,
    but at least I am slightly further forward. I can't see the BEN pids...are they to convert the voltage to the AFR ?
    I have boost via plx and fuel pressure via aeroforce 150psi sensor to set up next.
    UK spec 2009 HSV VXR8 6.2 LS3, E38, HeartBeat Supercharger running ~9psi,1 7/8" long tubes, cat back exhaust.
    Upgraded cam and springs of unknown specification, all I know is, it's a small cam with no overlap, suits the s/c.
    ATI damper, LS9 twin plate clutch, 548rwhp. twin PLX widebands to twin gauges.
    Currently running dismal HPTuners....NOW DUMPED !, Completed migration to EFIlive and slowly mapping it in.

    On the PIDs tab, look at the right-hand column, it is titled "Parameter", click on the title (the word "Parameter") to sort alphabetically on that column...

    then look down that column until you see the pids CALC.BEN_PLX1 and CALC.BEN_PLX2...

    the BEN pids are the correction multiplier, to see their definition do rightclick->More Info on each of them (on the PIDs tab).



    Summary: the AFR pids convert voltage to AFR; the BEN pids calculate the correction multiplier (to apply to your VE or MAF tables).

    If I add anyway, it lists it with the red cross through it:-

    I don't remember from your other thread... do you have an LS1B or an E38...?

    Whenever you see a red X thru a pid on the PIDs tab, on that pid do rightclick->More Info to see why.
