NGK AFX Won't Log In EvoScan 2.9
I have a NGK AFX wideband and I have the yellow signal analog wire going to pin 73 on the Evo 9 ECU which is rear o2 signal. The ground is going to pin 46. It's a 0-5 V output and 9.0-16.0 AFR range. The equation I derived for the EvoScan eval is 1.4*x+9. Is X the actual volts? When doing this it puts my AFR's at 177 on evoscan when the wideband gauge reads stoich. Also the reading on evoscan isn't changing as fast as the gauge does. It barely changes at all. Where did I go wrong?

Yes, i can't remember exactly what had to be done but I do remember that one of the hex files had to be modified. I know that doesn't help very much but it's been awhile sinse we did it. I'm running an aem v2 now so I can't even look to try and figure it out. Sorry
