Just like the rest of you I like going fast, and love ethanol.

My biggest issue however is the availability of ethanol in my area..

Not always having a ethanol pump around means carrying 5 gallon containers in the trunk of your car, or really planning ahead. Then you have to worry about running your car low enough so when you go from pumpgas to ethanol it doesn't drop your content mixture down too much. Let's not forget how there's a summer and winter blend, which will require different tunes..

So if you're not surrounded by ethanol.. it's almost not worth the trouble.. unit now.

So a few years ago I was on a personal mission to get True Flex Fuel Support for the platforms I work on the most - BRZ, GTR, WRX/STI. Yes, True Flex Fuel..No More Map Switching, literally PUMP and GO.

With the help of all the awesome guys (and gals) at EcuTek I've been able to achieve my goal / dream, Flex Fuel!

How it works-

We install a ethanol content sensor on the low pressure fuel return line, that sensors connects to a Zeitronix's Ethanol Content Analyzer (ECA). The Zeitronix's unit takes the digital signal from the ethanol content sensor and converts it to a 0-5 volt signal. My Flex Fuel kit sends that signal to the rear 02 sensor plug. From there EcuTek's custom RaceRom code does the rest.




My Plug & Play Flex Fuel Kit -














Dynosheet -



Going from pumpgas (93OCT E10) to E75 the car picks up just 40WHP and 50WTRQ!

Once the weather clears up we'll get some track times to backup the power

How is the injector duty cycle and fuel pump cycle not maxed out on stock components?

Nice work this seems very interesting!

The car has a upgraded fuel pump on it, suggested on STG2, and required on E85 tunes

Have you been able to play around with the gdi system yet too see if the in tank fuel pump will be sufficient enough for ethanol under wot as well as the injectors?

I'm in the process of doing those tests.

4K on my FXT running e85 with stock equipment.. But still doing more testing..

Have over 100 flashes in it.. Haven't had a single issue with it yet..

That's very cool. I know it's on the xt and it's a cvt trans so your prob not pushing it too much. But how are the Idc and fuel pump duty cycle at when you are running ethanol. I'm very interested to see how these subaru gdi systems deal with the leaner burning fuel.

Thanks

I'm giving my CVT a good push but I think there's a little room left to play.. I'll be a lot more aggressive when my 15 WRX turns up, can't afford to to break my only DIT car during this critical testing phase.

Is that model fuel pump recommended for stock turbo and eventually upgrading to a 20g type turbo?

Yes, that same pump would be good enough for a 20G setup

Ya i recommend fuel pumps on any WRX/STi doing any upgrades. You can never have to much fuel.

The flex fuel kit is so amazing, Nothing better then being able to go where ever you want and not having to worry about running out of gas

When I got tuned last week(ECUTEK), my tuner told me about the flex fuel option, but they don't have Ehanol here unfortunately..

Either way, good job and congrats...

This Visconti Tuning FlexFuel setup is just awesome. The install is super easy. Everything is plug n play. I did the flexfuel install outside, on the street. Crazy how far they've gotten with technology. This flexfuel system is true flexfuel. Throw anything between pump gas and E85 in the tank, and it makes adjustments without driver input. I don't think any other companies offer anything like this. The ethanol gauge also mounts very nicely in the new STI's. On E85, the car is noticeably faster, and has a whole lot more torque. E85 is also nice that it can make extra power with much less fumes.

If you're in an area that sells E85, this is a no brainer!
