We'll have to meet up.

Did Archie tune your IX? Is your car an AMS car?

Some how I managed to NOT include the very best E85 tip of all - Tephra map switching. It has now been duly added to the list as item #2.

i wanna switch to e85 but im just too in expirienced... seems like a lil more upkeep than normal. while the gains seem excellent im still on a evo8 turbo and stock trans/clutch at 78k miles.

Comparing HP/trq gained vs. dollars expended, I can't think of a better value in an EVO upgrade than converting to E85. Add to that the renewable energy benefit and the reduction to oil imports, and you have a winner.

E85, however, is relatively new to the auto and though the use is certainly wide, in comparison to gasoline it is very, very thin. That's why you will read a lot of 'teething' threads on this Alt Fuels forum when it come to using E85 in our beloved EVOs. These are threads of both caution and adventure.

We are all looking for the holy grail of ________. Fill in the blank with turbo, cams, whatever, or fuel. 105 octane at the same price as pump gas, may very well be the magic elixir we could only dream of years ago when only the rich kids could run race gas in their street cars.

I'm about as conservative as they come. I spent six months reading everything I could find on the Internet concerning E85 before I made the switch. I'm confident in my decision.

Food for thought: There is more than one reason to tune your car. If you could make the same power on E85 at 18 psi that you are now making on 93 pump gas at 24 psi, that still might make switching to E85 a worthwhile consideration. Making more power is not the only good reason. Making the same power with much less stress on the engine could also be a good reason to convert to E85.

Please ask any/all questions. I asked a bunch before I made the switch. You are not heading into uncharted waters alone.

Thanks that takes a load off my shoulders. so 1,000 cc injectors correct? I am currently running a stock evo 8 turbo but am going to get a tune before I switch turbo's. So I figured Id do the e85 switch now. Once I do upgrade my turbo will I need to get another tune?

You really need to decide now what turbo you plan to end up with and plan your E85 injector selection accordingly. If you want to turn up the wick, and perhaps go with a larger stock-frame turbo, then you will need at least 1,000cc injectors. If you want to go big turbo (>35R) you will want even larger injectors and twin fuel pumps.

Yes. Or get a laptop and Tactrix cable...

I have implemented just about all of the tips, and have been on E85 for 3 months enjoying the new found power of the stock 8 turbo. I was wondering if anyone have a recomendation for an inline fuel filter setup?
Thanks

I would like to do this as well, but, I'm lazy and have not looked into it very hard. Please post up if you come up with anything.

Check this out for water separation as well as filtration. It would be nice to have the clear bowl that marine outboard filters have so you could see the water in there if any. 90psi rated for fuel injected engines LOL 25GPM rated with 1/2' npt fitting. Good enough for that quad pumper jk...

I've been reading up on E85 vs 93oct and tuning. I'm clear on A/F's and the ideal ratios to run, but is there a "general" consensus on how much timing can be run on E85 vs 93oct? I have a ETS 58mm equal length turbo kit with 1000cc PTE inj. and twin walbro's intank with -10AN feed and -8AN return w/a Aeromotive fuel rail. I run 29-30psi from full boost all the way to redline. I just bought my evo and it looks like the ignition map (AEM EMS) has about 3* of timing around peak torque and only 5-7* of timing after that(5k rpms) to redline...8k rpms. I think the timing map needs some fine tuning as it looks very conservative from peak tq/boost?

I'm confused. Are you currently running E85 or 93? The timing map you describe sounds like a 93 map. But your question seems to be about E85. You should be able to run significantly more boost with E85 over 93 and some additional timing. It is all relative.

How does your timing map compare with MRFred's timing map?


It is from this thread: https://www.evolutionm.net/forums/6146288-post86.html. Which I would reccomend.

I'm lazy. I have found MRFRed's timing efforts to be much more successful than my own. It works great on my VIII. Very conservitive. No knock.

Sorry, I edited my post to clarify that I'm running E85....

up top my timing looks nothing like the one posted above..what turbo is this on, stock? Peak torque for my setup is right around 5k rpms where it looks like i'm running 2* adv. From that point up to redline (8k rpms) the timing only increases to around 7*adv.
