Changing stoich on the EcoBoost, does it always read on the gas scale, or does it change to the true scale for your fuel?
For example, WOT AFR with a stoich setting of 14.7 reads 11.5 on the gas scale.
WOT AFR with a stoich of 11.3 reads 11.5 on the "11.3" scale...and not the gas scale. Is this true?
