E85??

Anyone know if there is anything in the works for an E85 conversion for our third gens??? I think it would be great for the power we lack... Any thoughts, comments, or concerns???

 

You would have less power with E85.

 

It will only happen if someone figures out how to create big boost that needs the temp friendly benefits of e85, and both will require an ECU replacement.

Neither of which is trivial or cheap.

For the effort and $, it would be about as practical as swapping in a v8

I do like the french fry exhaust smell of e85 though...........

 

Arent there second gens out there with an E85 conversion?

 

Most vehicles will compensate enough to run e85 now. You will gain nothing. Just lose gas mileage.

I run e85 in my 1990 eagle talon. 30+psi, 22* max timing, aggressive AFR. Stuff is magic sauce when running boost.

 

Im sure someone somewhere, but for stock applications there is minimal benefit to e85. Why do you want to convert?

 

4.0s have SCs available, and some folks have turbo'd, so those applications may have some creative stuff happening.

I suppose someone might run it on an NA vehicle, but I have no idea why they would bother.

 

From all that I'm reading, when running E85 you gain power and run cooler... You'll need to run richer, which in turn, may lower your gas mileage.... Still don't see a downside yet. This is just speaking about NA cars; from what I know FI engines see a lot higher output increase than NA does

 

What kind of injectors does the tacoma use and are we on that HPFP? Also, E85 is supposed to rot standard fuel lines if you leave it in there.

I'm all for E85 FI motor, but E85 raises the octane rating and requires a lot more fuel for power.

 

You only gain power if your motor is at the limits of pump gas. In an N/A stock motor car its very low compression. So no timing being pulled because your not detonating.

E85 gives you power when you start pushing limits of pump gas. Its like adding race fuel. It takes a lot more to detonate so you can run more boost, more timing and more compression.

N/A high performance motors like F1 need e99 because of the compression and timing they run.

E85 is about 20-30% less dense than gas depending on the mix. So you can loose a good amount of gas mileage. My talon gets about 150-200 miles a tank and before it could get over 300. It does not run richer. You must add more fuel to get teh same air fuel ratio. So your using 20% more fuel but its not running richer.

E85 goo is an issue also. Something breaks down after time and clogs injectors. We have to run a tank of gas every few months to help keep the injectors clean.

 

You would also want to buy some sort of hand held tuner that can flash between E85 and standard gas. E85 is a great alternative to race gas.

 

Yes my talon has three tunes. I run a program that reflashes the eprom on the stock ecu that was socketed and replaced. Street tune, race tune and gas tune. The stock ecu can handle up to 2000cc injectors with this tuning program.

 

Did you make 405/420 whp/tq @ 6200 elevation? If so, that talon must have been fast.

 

Yes but the dyno adjusts for elevation. The car only ran a 12.1 at this altitude. But 60foot in an AWD with a small fast spooling turbo is rediculous.

 

this was an issue on my last VW which had a similar NA 3.2 V6. conversion to e85 required a lot including all new injectors, pump, other fueling bits and some very expensive custom software, not to mention better exhaust flow which could be the achilles heel with the 2GR-FKS. you can increase flow significantly with available parts but that removes all 4 cats, gets codes, needs software that isn't available yet...

 

I run E85 sometimes on my 2001 TRD S/C as it's non-intercooled and I have a piggyback that affords me the ability to a) run much larger injectors b) switch between maps. I did this with my AEM FIC and modded my Greddy EMU to remotely switch maps (remove the switches on the side, install header, make extension cable, 3 pole switch etc), still need to install the cable and switch as I recently switched to the EMU and Split Second for the o2 sensors.

JayRolla pretty much raps up the thread and hits all the pointers.

If N/A, I wouldn't bother. There are some interesting kits to convert cars in places like Brazil that are oozing in e-XX. Unless you live somewhere where you must run it, or its so heavily subsidized that even at the MPG drop it still saves you cash, I don't see a reason. For boosted people, the tree-huggers hooked us up big time- subsidized race gas that is cheaper than 91 octane- pretty much offsets the loss in MPGs.

 

My future plan for my 4runner with 3.4l is a holset hx35, greddy emanage, e85. I hope I can get the emanage to work.

 

I'm around on the forums and can help- I got tired of diy wiring my ems so I just went with boomslang for the harness this time around.

 

Forgot to link here, already made a thread about it, will be awesome if other peeps start messing with the setup too. I got lazy and fell off on installing the knock sensor and other stuff.

Wow that is very informative. I have an old greddy emanage blue that I used on my talon before going with ecmlink (ecu flashing tool for Mitsubishis. Has speed density and fuel cells for tuning like a full standalone). Sounds like a lot of work to get it going but would be nice not to buy something else if I didn't need to.
