    Anyone hear of the map sensor hi resolution pid? Where do I find it

    I was told people are using a Hi Resolution pid for the map sensor? It helps for measuring boost properly on GenVs I'm guessing. I can't get proper boost readings on GenV stuff and was told this might be why.

    The latest version of HPTuners scanner has a math PID for boost which is accurate. I've compared it against my hi res signal for MAP and it matches. In fact, I had to monitor hi res MAP or manifold pressure for it to populate data. The Boost PID does math and takes the barometric pressure, subtracts that from hi red MAP and then converts the KPA value to PSI.
    I've tuned a few things...

    I had to update my HP to get it I guess. I can select it in my channels now after going to 4.4

    MAP - Hi Res has been in the channel list for years.

    Manifold Absolute Pressure - Hi Res

    Weird, I couldn't get it to pop up until I did the update.
