Flex fuel and supercharger?
 

Just out of curiosity, could you run a flex fuel kit with a supercharger kit and still realize the benefits? Here in AZ, we have E85, but only in select areas so it would be nice to fill up with it when you can, but not be penalized when you cannot. I understand you can have 2 separate maps, but could you just let it run at whatever % ethanol you have on a single map? Thanks

They aren't mutually exclusive, you can have both in one map - just need a tuner that understands how to tune for both. I have a flex fuel setup, plan is this year to go supercharged - just evaluating options for who can provide what, tunewise. Hopefully some of the vendors can chime in on what they offer, otherwise you're best bet is to go ask them directly what they have experience with.

Yep, you can. @DeliciousTuning supports that setup.

This is something we're considering exploring in the future.

it sounds like in your case you'd able to use either of the two ways of going about using e85, multiple maps and flexfuel.

currently i use multiple maps because i'm using the ecu input where the eca would go for a wideband sensor. i do this with racerom, with maps 1 and 2 being pump gas, 3 and 4 being e85. it works fine, i just run as much gas out as i can (doesn't need to be super low but it helps), fill up with the new fuel, drive around until the trims go nuts and then switch the maps while driving. it's not bad at all, and i don't change back and forth often anyway.

for flexfuel you have a single map and an ethanol content analyzer wired to the ecu. the tuner then creates custom maps with ethanol content as an input which handle all of the compensations for fuel, timing etc. it's actually really easy to do once you look at it, certainly easier than maintaining multiple maps. to the end user, it's the 'set it and forget it' option once it's tuned properly.

if you can plan ahead to switch fuels then you can use multiple maps. if you want to switch 'on the fly', get flexfuel. that's really what it comes down to.

I am also in AZ and definitely run out of E85 options on trips.

The flexfuel + vortech sc setup I use works great.

I'm planning on doing the flex fuel setup as well. @DeliciousTuning will be doing my tuning as well. I'm running a Turbo setup, so while its not a supercharger it is forced induction. I like the idea as well that I can run any mixture between 91 and E85.

I was running flex fuel + vortech here locally in phoenix.

This is what I'm after. I like the set it and forget it style. One less thing to stress about. Thanks for all the input.

Seems like a few of you are already doing this, so that answers my questions. Any local (AZ) tuners do the flex fuel + FI for these cars?

I have flex fuel on my vortech supercharged brz. I can run any E-# content :)

Guy here locally is running it with his innovative supercharger.

I'm also looking to explore flex fuel on my Vortech. So Delicious Tuning is the way to go in SoCal huh?

I am running a @DeliciousTuning flex fuel Innovate set up.

Goodspeed in Scottsdale.
