i was wondering if anyone would happen to know if there's a way that i could set up megatune to read a proper afr. right now, i set the settings.ini file up for the "unknown w/b o2" or whatever setting that is. all it displays in megatune is the voltage, well, that's not too useful to me. but it is registering, just not in afr. its a linear sensor, and its range is 0-5volts and it reads afr's from 9-16:1 any suggestions? i tried searching and reading the manual, no dice. my control unit and sensor are a part of the ngk afx kit.

 

I would try cycling through the various widebands in the software until you find one that's a match.

 

Do the same thing the AEM users are doing make a chart chad did the same thing and his works fine.
