Default 100% methanol seems preferable

Have posted some info on NASIOC about this, thought would also put it here at Ed's request.

Tried pump fuel tune, mid 11s AFR, 328 WHP on Delta Dash, 19 PSI at peak power.

Added methanol/water injection as screenwash or 50/50 mix and it didn't gain much and detted with high EGTs, tried various different mixtures/timing.

100% ethanol injection controlled the det better and took more timing and leaner AFR, but did not make more than about 335 WHP.

100% methanol injection about 10% of the fuel did 341 WHP.

10% methanol in the tank did 364 WHP.

I tried to optimise AFRs on each setup.

Anyone know how a Techedge wideband will read with a 10% methanol mixture in the gas tank? False high or false low? Seems nice at indicated 12.2 AFR.

Comments welcome.
