    I'm running a 40% ethanol blend right now. I just switched over. after reading this, I realize I can richen the afr up some more. I was going for an 11.5 afr, but since I'm running 40% ethanol, can/should I go richer, and how much? also, the only thing I have changed in the tune is the maf table, because the E40 runs a lot leaner. one thing I noticed today when I was crunching the numbers to get the E40 is that since the gas pump has E70, if I mix equal parts of E70 with E10, it will make E40, so getting the right mixture is easy.

    I also have 42.5lb injectors
