Considering e30 tune on mrx setup

[jtthirdeye]

It’s been 50k great miles running 93 octane on the mrx setup. The car has embarrassed many a vehicle on the interstate. I’m reaching out to see if anyone has a similar setup (mrx, fmic, intake, catless dp) and runs an e30 tune? If so, how does it run?

Would be nice to have a 4th map on the accessport for e30 when I’m down to party but also be able to switch back to the ol’ trusty 93 octane map for commuting.

Once you go Corn...you will never go back. Mileage goes down...car runs just as good as if it was on Gas. BT here with Aux. on e50-e60 It is totally worth it though!

I only switch back to 93 when it's cold and/or I have a long commute. Have to time your fill ups more carefully when running ethanol depending on availability.

If I have an estimated 100 miles left in the tank, but an 80 mile commute round trip the next day, I'll probably fill up that evening, or first thing in the morning.

I'm curious as well as I plan to do this on my MRX setup which I'm also currently on 93 but am thinking of going injectors and HPFP before tuning for e30. Might be overkill as I'll run out of turbo anyway and it's expensive.

When I do get around to it, I'll post a dyno chart. I posted my setup and dyno results for 93 in the data logging section.

What type of hp increases we talking going from 93 to e30?

I haven't dynoed...dizzys website breaks down what to expect with each fuel. While the hp does go up, it's the torque that really sees an improvement.

According to my tuner, there isn't a ton more headroom on the MRX kit but he did say we should be able to hit 300's which would be plenty enough for me. At the end of the day it is outclassed by the S280 in terms of power output but even low 300's is plenty for this car.
