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.
