    Innovate MTX-OL Wideband Serial Output with MPVI2

    Looking for help transforming the Serial signal from my Innovate MTX-OL Wideband. In free air the gauge is showing 22.4 AFR and HP Tuners is showing 20.8.

    I assumed I could make it work, but I'm struggling to figure out the math. I should've just bought the AEM but I went for looks instead, beginning to regret that decision. Also trying to avoid running through EGR or A/C Pressure or paying $249 for pro just to log Wideband.

    Thanks for any help.

    EDIT**** Apparently I'm an idiot, but at a certain point of lean the output defaults to percent oxygen. (20.9% is normal O2 in air) Once installed it read perfectly...couldn't figure out how to delete thread.

    I'm actually going to try and run the serial wire from my aem wideband to a USB uart and see if it reads that. If it does, it only costs 5 bucks and you have to use another USB cable, but I don't see any reason it won't work. I'll let you know if it does.
