NGK AFRM in hptuners help I've got the NGK/NTK AFRM 96604. 0.5v-4.5v and 9.0 afr to 20.00 afr. Doing my math I can't get the display screen to show anywhere near what hptuners says. I need it set up for lambda but when I'm showing 1.08ish on the lambda scale my display is showing 12.x. Can somebody help me with the math for this . Lambda is 0.62-1.37. I've used the tuning school spread sheet and it still not correct.

But Incase someone needs the NTK AFRM formula (volts 0.6363 + 7.67).. That worked for me for AFR reading
I just went through this yesterday with a different wideband. I'm not trying to say you also overlooked this, but like an idiot, I used 5v x 10 in the custom user defined enhanced i/o. Supposed to be .5 not 5
Just thought it would be worth mentioning.
Chased my tail for a couple hours thinking my math was off...
