Quote: 14.5 to 1, 4.90's in the 1/8 good? Run it right out of the pump. I do run methanol and gas to test stuff on occasion. What do you want to know?
just curious how much difference is there between the tune on a gas vs E85? I bought a quickfuel 950 E85 carb a couple of years ago. I also bought the FAST E85 wide band. it would tell me one thing but the car another. if that makes sense.
The wideband is just a tool, you have to listen to what the engine wants. As far as tune difference E85 seems to like less emulsion, and smaller holes in the emulsion channel. Passages need to be larger than gas, depending on the carb size as to how large.
yea thats what I did, everyone swears by the 02 but it didn't do anything for me. I gave the motor what it liked despite the 02 telling me to go richer. was a .2 swing from what the 02 wanted and what the motor liked. even had it on a chassis dyno that did the same thing.
Tony... are you using the lambda scale... being that E85 is 30% more fuel to get the same BTUs you shouldnt be reading on the gas scale.. also.. E-85 has a much wider window to play in to make it go fat or lean.. you might have 3 jet sizes(or more) and still be on the sweet spot..... just saying
