Well I put the Methanol in the tanks and fired it up on the E85 tune.
It ran great as always for a while until the lines were purged out. Then it started to run rough.
I switched the "fuel energy constant" number in the FAST XFI program from .65 for E85 fuel to .43 for Methanol.
It started right up good again and it was a little lean on idle. The O2 sensor reads the methanol just as well as Ethanol.
I richened up the idle and some parts of the map for a minute and it ran good.
Idles just as smooth as Ethanol at 1000 rpm. Great throttle response.
Warmed right up same as ethanol. Didn't run cold like I expected.
Shes ready for Hardy.
