Fuel mix cheat sheets

[Enki]

Got tired of fixing shit once a week, so everyone gets to use the static sheets until I can figure out how to turn the calculator into a wiki page.

Quick and dirty basic calc in html format. Should work on all browsers/platforms, though I couldn't figure out how to open the html with my browser on my phone; gave up after 30 seconds.

Brilliant work, came up looking like an unknown file in chrome but it opens fine and works a treat, the cheat sheets etc in this thread are priceless with how easy it is to mix/tune...Thank you sir

[Enki]

I'll eventually improve the looks and functionality and whatnot in this file, but for now, it's better input wise than the static sheets.

OP updated.

Downloaded file is corrupt for me... Alternate link anyone?

Edit: Nevermind - Winzip thinks its corrupt, 7zip work fine. My dumbass company uses winzip for a default.

I know ethanol and methanol have differences in their stoichiometry

1 gallon will trim out to almost nothing; probably not needed to tune for it.

I guess I'll try using the same fuel gravity and injector scalar values for 1 gallon of ethanol and see how it goes. Also, how do you tell if the values are off? Will the LTFT's be out? Or will AFR at WOT be out? Sorry I'm new with fueling stuff, Thanks

You don't need to tune for a gallon of methanol in the tank. It will be more of a headache than it's worth.

Okay gotcha, but out of curiosity, would not tuning the Fuel Gravity and Scalars make my Actual AFR's read slightly leaner due to the added oxygen content from the methanol? Or would the ECU compensate by adding more fuel,

making my LTFT's more positive. I can understand that running much larger percentages of alcohol in the tank would require Fuel gravity and Scalars to be modified as the variance in the MAF Curve would be out of spec to the

point of triggering the check engine light. Does it sound like I have the right idea? Cheers

You will notice more positive LTFT's. I would not sweat over a one gallon mix.

Okay thank you. Do you think I will be knock limited with only 1 gallon in the tank? I'm just wondering if I should street tune it, or take it to a dyno.
