Switched from gas (110) to Ethanol (E-85) Thought I'd post the numbers for those interested. Only change was E-85 and a tune. First numbers on 110 were STD, E-85 are SAE. This is a n/a 7L LS1 through th400, 12 bolt and 28" tire.

Can you explain the difference between STD and SAE #'s? always see it but don't know the difference.
Also how much difference in total timing did it change from gas to the e85? and did you have a wideband on it?
what plug and gap?
sorry for all the questions lol, just did the same thing myself and i'm getting my junk tuned in a couple months. thanks.

I would have to ask the tuner about the timing change. I couldn't tell you. He did run a wideband on the dyno.
Plugs are TR-55s at .40. I may switch to TR6s though because I think I'm going to spray it.

I'm probably not the best to explain the difference between SAE and STD. I think there are several posts on here if you search for it. Basically STD #s will read higher than SAE, but SAE gives more accurate numbers. I've heard anywhere from 2.5-4% difference. There are correction factors involved that do the calculations.

not much but just a quick search.
I would be interested in seeing how much more timing it wanted. I've yet to had mine tuned but i'm guessing it'll want 3 or more degrees.

got ya, Maybe someone else can chime in because i've always thought on e85 you want to run a much colder plug, like 2 to 3 steps colder and you want a non projected tip plug. At least that's what i found in doing my research when switching over to the fuel. I would seriously look into the plug deal, i think you may be using the wrong plugs.
