E85 MHD

Mixmaster · 01-22-2017, 05:23 PM

I have just ordered a fuel it stage 2 pump and am looking for to trying one of the MHD Maps. I am currently FBO excluding outlets and running an aggressive 93 wedge tune and hit around 20psi.

would both the 40% and 60% off the shelf e85 maps be a noticeable difference? Also can I now go to straight 60%ethanol or are there still other limitations?

Cheers

Post a log of your 93 map.
If i remember both MHD maps target around 18psi.
However the e60 map targets about 14 degrees of timing advance, so you will feel the difference. I recommend starting at e40 and looking at your HPFP to make sure it can keep up.
