Methanol is not only a fuel, it also adds significant amounts of oxygen to the mix. While the additional oxygen is not nearly as much as NOS, it still must be taken into account when tuning. Being both a fuel, and adding oxygen, methanol alcohol significantly changes the stoich value of the mix. When injecting larger (>20%) quantities of methanol, the impact on trying to tune to target A/F ratios with a wideband oxygen sensor set to gasoline's 14.7 stoich value becomes more difficult.
