If you want to get technical about it most people should have it set 14.1. I have not seen any pumps recently that sell pure gasoline.

 

I have never noticed a difference in setting that AFR 10 14.1 or 14.5, so i just leave it at 14.68

I am not saying do it or don't do it, that is just what i do....

 

Same here Corey. I changed mine to 14.10 and the truck felt less responsive but maybe it was just in my head. So I put it back to stoich for pure gas.

 

i figure without an ethanol gauge it would be hard to set it to strictly 14.1 maybe meet in the middle around 14.4 since i believe the e10 is at most so you really never know what to have it set at unless you switch wideband readings off of afr.

I will have to do some reading up on those fuel tables.

 

I looked at your tune, I like the way you did the spark tables. It looks like you are using the boost timing table to pull timing from the low and high octane tables. How is that working for you? It looks like at higher boost levels you are only running a 4-5 degrees of timing?

 

Many lakes will sell pure gasoline near them.

 

I tuned my spark table for vac/boost up to about 3-4psi where it get to 1.20gycyl on the far right of the table.. so it should make decent power in that range.. then use the Boost timing table to pull timing for more boost.
