    p59 dbw 2bar OS wideband to egr pin blue-55 not reading

    hey all,
    I'm currently trying to get my aem failsafe wideband to read in hptuners.
    I had found a thread here and on ls1tech saying that the p59 pcm uses/used ping 55 in the blue connector for the EGR position sensor.
    I've wired said pin from my gauge output, however i'm not getting a reading.
    I'm using an 04 p59 pcm that didn't have EGR to begin with.(aforementioned threads said it should still work)
    I'm not getting any reading from the "EGR sensor" and I THINK I've enabled the EGR.
    The threads mentioned table 210, which I've setup with both items set to 0, and 250, with no difference.
    egr enable table 210.png
    any tips or pointers would be much appreciated.

    Do you have the stock file still?

    See if on the stock file if there is a an enable/disabled box in the gas recirc tab.

    haven't been able to find that tab, the only reason I can find the other deal is through the search, like shown. no stock file unfortunately. bought not built.

    I have the beta, so I can see the new tab.

    Otherwise if you use the navigator under the edit tab, there would be a an exhaust folder listed. The enable/disable is there on stock files for sure.

    If you can't get the EGR to work you can use the AC pressure sensor.

    using AC pressure would disable the AC correct?
