I'm trying to tune in my fic using the all the maps. I have the fuel map down pretty well. Im unsure about the maf voltage and the O2 sensor. What does the O2 sensor voltage control? Also the voltage clamp I have set at 5volts.

 

Go to F/I and search. All inclusive F/IC thread explains it all. AEM videos also explain it all.

 

what he said...lol
