So the time finally came this weekend to convert my daily driven 2008 Evo X GSR over to the new TephraV3 rom with all the flex fuel goodness. My good friend and tuner Tony as UMS Tuning handled all the tuning via his Dynapack (in case anyone is wondering this Dynapack has the updated software and reads within 1% of our local DJ). Little background on the car, its a daily driven 2008 Evo X GSR. It currently has 82k miles on the motor, turbo, drivetrain, etc. It is your basic bolt-on car. Last time it was on the dyno the car made 362whp and 362wtq at 26psi on 91 ACN fuel. The stock fuel system was pretty much maxed out. I'm very fortunate enough to live 5 miles from Injector Dynamics and I race with the owner in NASA, so I got hooked up with a set of fancy ID1300's. At this point I shopped around for fuel pumps. Decided on the DW300C cause it was the only one that was a 100% drop in 300+lph pump and had a killer warranty, hopefully it holds up. As far as the flex fuel kit I decided on the flex converter setup cause it was all plug-n-play and the bluetooth feature is just plain awesome (really hope it works on the iPhone really soon). Once we got everything installed we started tuning with 91 pump gas in the tank. He got everything dialed in and at 26psi on its best run the car did 358whp and 361wtq. Not too bad for this brutal AZ heat. At this point we drained the tank then filled it with E85. However we all know that it takes a little while for all the pump gas to get out of the fuel system so with just E85 we were at E76. So we added some E98 into the mix to bring it from E76 to E85. Once we got the ethanol content to E85 we started the tuning of that fuel. The target boost was 30psi. On its best pull the car made 406whp and 411wtq. Peak torque came in at 3500rpm, little freight train. At this point we started adding 91 pump gas into the system. We got the mix to E50-55 and made a few more tweaks. It's best pull at E50-55 was 380whp and 383wtq at around 28psi. The tuning was finished at this point. The car feels amazing. Pretty much the perfect street car in my opinion. There are a couple issues I would like to address, first being the DV. I'm sure its leaking like crazy. Either gonna give it a little crush or will upgrade to a Synapse DV. Might even borrow the Cobb DV off of my IX. Also will have to be conscious of the bottom end as 411wtq at 3500rpm on the stock rods is pusing it. Aside from this I think the car is pretty much good. I will enjoy it in this current state for a while. I also have a MAP cast manifold and a MAP EF2 with a MHI ported and coated hotside sitting on my shelf patiently waiting to join the fun, but i'll wait a little bit before I install them. All in all I am very pleased with this setup. I highly recommend it to anyone who swithces between pump and E85 often. The convenience factor alone is worth the extra money for this setup. Shout out to Tephra for taking the time to develop this. Thanks to flex converter for the killer flex fuel kit. Lastly thanks to Tony at UMS for the amazing tune.

Best pulls of the night (4th gear):

358/361 @ 26psi on ACN91 from Shell
380/383 @ 28psi on E50-55
406/411 @ 30psi on E85

Pump gas AFR - 11.5
E85 AFR - 12.0 - 12.2

This is the dyno sheet of a few of the over lapping runs, I thought I got a pic of the best runs but it turns out I didn't. You get the idea though. (Ignore the low boost 15psi plot and afr)

When I left the tuning session it had E54 in the tank. Just filled up with a full tank of E85 at the gas station and now it's at E70. This is now the best mod I've done to this car. No more map switching, no more draining it down to the fumes to switch over, and no more driving like a grandma for 15 miles to make sure that everything is safe. Literally fill up with whatever fuel and the ecu takes care of the rest.

Numbers are great and the car looks great as well ! Congrats and Enjoy

Thanks buddy, the car on straight E85 is an animal.

Life changing

Evolved 3RS

Nice. Looks like this is something I'll be doing soon.

Definitely looks pretty good. I'm tempted myself to get on E85 but I recently just hit bolt ons and I only got my car about 3 months ago so perhaps I should slow down lol.

Question, how long did it take you guys to narrow down the fuel and how much time did you spend on the dyno?

I had my Evo 10 on E85 and 100+whp/100+wtq at 900 miles.

Crosxs

On second thought....

Its tempting. I get the feeling I want to do flexfuel and a turbo upgrade but I still have bolt ons to finish as well...

I love this car but theres always something in the pipeline for it.

here you go,

Stock turbo, four mods for +100whp at 900 miles, and stock turbo, five mods for +130whp

From yesterday - Stopped by my buddy's place and he download the BlueFlex app on his Android for me cause I'm a iPhone owner and its not available yet. His Galaxy picked up the signal immediately. When I left the dyno on saturday I left with a full tank, I since drove the car until it got half empty. It had E54 in the tank. Picked up some E85 from the station and poured it into the tank. At around 4 gallons of fuel added the ethanol content increased to 66.9% (E67). I then added another 2.5 gallons and it increased to E72. Seems that for every 1 gallon of E85 added 3% of the overall ethanol content increased (results will vary based on ethanol blends and how much pump gas is in the tank). The app is awesome. Need to find me a android

that's pretty awesome. good for you OP. If you don't mind me asking, what did the whole thing cost, tuning and all? The last quote I got from a tuner was around 2K for all the fueling upgrades and the tune/blending. does that sound about right?
