    MPVI 2 and pro link question

    Hi all,



    Holden LS1 ute 2001

    Im currently running an AEM 30-4110, i have the white wire hooked to the red 5v wire. channel list for gauge 0.543 to 10.3?

    Currently Logging but the issue is the wideband signal that is received into the vcm scanner is different to the gauge.

    My issue is i'm stuck on the sensor parameters of the gauge i have made sure it is reading in AFR and not lambda its easy 20% out in the tables. could it be as easy as the parameter correction for the gauge causing this/incorrect reading discrepancy on has it something to do with the selection on the afr gauge with maybe the 4 position thing?

    I am just unsure as i have red alot on the forums by searching and have solved all my other issues bar this 1 the uego sensor is mounted correctly with not air leaks on the bunge mount as well.

    I hope this is enough information for help as i have the data log from the car on the computer at home and not avaliable at the minute

    Cheers

    P0 and P1 in analog Output voltage modes

    if i was the calibrate it at 0.000 AFR=10 and 4.250=18.50 would this look correct?

    working that out to 2.125= AFR of 14.25?

    Put your gauge back to default settings

    The scanner should be set up like this... Should just work if you've wired it right.

    do you have the wideband hooked up with the white wire to red 5v to get this on the to work on the pro link?

    I am starting to pull my hair out i have followed all instructions and have around 13.5 reading in hpt to 10.8 is on the gauge

    Yeah dunno man. Should just work if everything is set up as default parameters.

    You can muck around with the transform to get it to read right but you shouldn't have to do that.

    yeah no dramas ill keep tinkering did you hook up the blue wire or just the red 5v on the pro link?

    Don't have a pro-link, but red or blue should work. Make sure its got a good ground. Preferably to the same ground that your wideband gauge is using.

    yeah it is thanks check the ground voltage as well.

    grounding is done in a 3 way joint, red 5v hooked to a white wire off the uego.
    it surely has to be a calibration issue even @0.5 volt plus 10/or .588 + 10
    maths is correct at 14.7 afr
    p0 for afr 5v is in place
    In desperate need of help my l98 in lamda works perfectly out the box.

    Pink means the sensor is not in your channel list. Since you're using analog you wouldn't be using that PID anyway.

    Post up a log, I'll take a look.

    thanks for that ill get one through tomorrow that makes perfect sense would you happen to know the voltage offset for the 4110 pretty close to it reading but a bit out still.

    There is a transform (channel) already defined for your wideband. I pointed it out in a screenshot earlier. Try that.

    faulty sensor out the box swapped it out +9.8v and its spot on, thank you to hjtubo for your input appreciate it mate!
