lol, and probably 150whp more :giggle:

I was thinking of using a flex fuel just to account for variations of ethanol blend.

Or just save the 500 or whatever it is and tune conservative.

There isnt' that much difference in power between 11.5afr vs 12

whoa whoa whoa 500? dude I'm going to pull one from a junkyard taurus for $15.

lol

I thought you were getting a new one from innovate or tuner tools

Mine came from an s10 and that's what I paid. was a PITA to get it out, I'd highly recommend a taurus if you can find one.. they're all gone from the taurus's in our junkyards.

yah I was reading and it's by the effin frame underneath the car?
where is the taurus sensor located at?

What fuel system upgrades are required to run this? All new lines? New gas tank? I know you'd need to make sure your injectors can flow the extra fuel. I've thought about E85 in my DD 1.6L.

I don't think you're required to do anything other than run huge-ass injectors and a pump.
However, I'm going to convert my entire fuel system to -8AN lines/diy SS hard lines/dual feed rail/etc. Mainly for the piece of mind - my current fuel lines look like aids.

That sounds expensive. I just feel like any rubber hoses and o'rings in the system probably aren't rated for ethanol and will clog injectors.

On the s10 you have to remove the *metal* fender liner to get to it, and its bolted to the frame, there's a small chance someone with the right build could get it out from underneath... But most of us have to pull the 10+ bolts holding the fender liner in. The taurus's are near the passenger side strut tower.

Maybe I am over thinking this, but what do you do when switching between E85 and pump?

Clearly you must change maps, but when do you make the switch if you still have a gallon left in the tank at fill up? How long do you stay out of boost?

You make the change when you're empty, or you always fill when there's 1 gallon left and you tune on that mix. You can't screw with the E85 mix without taking a big risk with the engine.

I switched Theseus to E85 2 years ago. The hassles are well worth the performance and safety benefits.

Which is exactly why I'm looking at getting an AEM flex fuel standalone. No switching maps - it does it for you based on % ethanol.

Have you guys seen how ProEFI integrates the E85 sensor? It's pretty nice (cheesy video warning):
The box alone is $800 and it gets really expensive as you add sensors though. :vash:

I may have posted this link in another E85 thread, but here is a good source for finding locations near you: http://e85prices.com/e85map.php

I am hoping to make the switch this year.

Most of the tracks I go to are in the middle of nowhere (no e85 within 50 miles). Im afraid I would need fuel mid-event and be SOL. I dont want to lug around a 55gal drum of e85. Also, I go to a track or 2 in canada, so I am not sure what the rules are for transporting large quantities of fuel across the border.
