How does it do this? Through oxygen sensor data? I am still curious.




GM use a flex fuel sensor to measure etoh % so it can fuel and time correctly. This data is considered by the olm.

So this will only be applicable to flex fuel vehicles? Wonder if any other manufacturers besides GM have this capability?
