You will have interesting issues with the OEM ECM calibration running methanol, even in a mix. The air/fuel ratio is controlled by a wide-band planar sensor before the cat. Stoichiometric for methanol is around 6:1, gasoline is 14.7:1. Methanol is a great fuel for FI, it brings a huge amount of cooling to the combustion process, so you can run more compression without detonation. The bad thing is, your wideband O2 sensor doesn't know you are running mixed fuels, so it may not get your gasoline fuel ratio right, it may run very lean and be very unhappy if you don't tune specifically for methanol.
As well tuned as the tC is running 87 octane at sea-level, it's hard to imagine methanol will do much good for you without some kind of forced-induction system. If you want to discuss methanol and forced induction, that's a completely different thread.
