6 Gallons of E85

[BrandonHall10]

In preparation for the 42# injector no tune E85 conversion, I am trying to "up" the ethanol content in my tank. I put 6 gallons of E85 in my tank on top of 11 gallons of 91 octane (E10) to bring it to full. If my math is right, that should be about E36.

I'm seeing SFT's of +/-1.5

and LFT's of +14 to +11

On stock injectors still. Does this sound about right?

FWIW, car ran normal.

About right. Should run pretty good up to 50/50 bbuying the ltft at 16.

Thanks!

When you do pure e85 and 42s expect trims around 10 as well.

Good to know. I don't like surprises!

When I eventually install my wideband, what kind on numbers should I expect to see? (On e85 and 42s)

Hope for mid 11s at wot. Get a fuel pressure gauge on before you worry about the wb to make sure you hold pressure at wot on the 42.

I have one mounted to the rail. I suppose I should have one I can monitor while driving.

Also already have the walbro 255 in a venturi can. Probably ought to to the fuel pump rewire soon.

Fuel pressure denial is pretty common but its easy to check. I dont have a wb gauge on any of the race cars just a fp gauge...
