Running ~30% Ethanol w/93 octane in LAP3USA ECU tune (Stage 1.5+)...
So as you can see from my signature, I run the LAP3USA ECU tune (Stage 1.5+) with lots of bolt on performance parts. I normally always run 93 octane (E10) Costco/Exxon gas (Top Tier only) and love the way my car runs.
Since LAP3USA now has a Stage 2 tune that requires running a E30 mix (or a water/meth injection system), I decided to "experiment".
On a nearly empty tank (~50 miles range left which means I had a ~2-3 gallons left), I put 10.725 gallons of Costco 93 octane (E10) gas and drove to a nearby station that sell E-85 or more specifically "FFV Gas" which is E51% min (and can be up to 83% Ethanol for summer months) and put 5.055 gallons in which it topped off the 18.5 gallon tank.
By my figures, that should be basically E30. I began my 20 mile drive home (~78°F ambient) and after a few miles noticed a bit more "pep in her step"! I didn't do the gradually change-over, I just went straight for the ~E30 mix. I'll report back what I find. I did hit peak boost at ~20.5psi on one WOT run to the barn. So far so good!
What have others done and experienced with running more Ethanol?
