Hi,
Does anybody know how a wideband O2 sensor would read methanol?
Stoich for gasoline is ~14.6:1. Stoich for methanol is 6.4:1.
My theory is that since the O2 sensor reads the percentage of oxygen left in the exhaust, then really it's reading a lambda, not a A/F ratio.
The reason I need to know is I run a gen-7 DFI w/ wideband so it's always in closed loop, and I'm considering replacing some of my fuel with methanol. My setup is set for 12.5:1 at WOT, so if I switched to methanol, it would be quite lean (since it needs to go in at about 6:1).
So, my question is whether O2 sensors actually read lambda and calculate to AF ratio or not.
Thx,
Steve
