answered alot of my questions, thanks guys

 

There is some very useful information in here. It just sucks to have to browse through 26 pages. THERE IS REALLY ONLY 2-5 PAGES OF USEFUL INFO RELATED TO THE SUBJECT/TOPIC

CAN THE MODERATOR CLEAN THIS THREAD BY DELETING ALL OFF-TOPIC RANTS? MAYBE MOVE UNRELATED RANTS TO "WHY NOT TO RUN E85"?

 

I just started using an E85 mix. Didn't want to do a full tune and injectors so I figured it would still increase the octane rating of 87. I used 1.5 gal (10%) and it runs a lot smoother with 80-85% less ping. This is with the RFG tune (hypertech). Switched to the non-RFG tune and it sounds different and feels mildly more torquey. No engine lights, starting problems, ect.

 

Heck if it cleans your enternals as good as ive read on here i wanna use it.
im a clean freak when it comes to my car. i dont think i could bring myself to put that much money into using it though with injectors tuning and all that though. if i had the cash id prolly do it.
just curious what would it hurt if i used it in my tank?
i mean from what ive read (not that i know anything about this) but could you use this almost the same as like an additive of sorts?

 

You can use up to a 50/50 mix on any modern injected car. Beyond that u may get a check engine light that will code as bank to lean. Back the mix down and it will usually clear itself. Ford escorts won't they must be cleared with scanner.

A few gallons in a tank is a great octane booster

 

Just a note regarding above: You can buy methanol off of Amazon.com you can buy a 55 gallon drum for under $190 or buy the Home Distillers Workbook and make your own.. Mix it any ratio you want..

 

So I have to ask, are you running actual fuel line? In the late 70's we dealt with rubber methanol and fuel line so all fuel line is rated as such since 1982. Any Gates or Goodyear hose is approved for gasahole or bio diesel. Both have Teflon or Vitron liners to protect the methanol from compromising the hose. Real fuel line is rated, Red or Blue stripe. Go to GreaseCar's website if you cannot find it anywhere else.

 

I've resolved my issue. I run two pumps and when I added the 2nd I had rubber lines to connect into the system...fixed that with hoses from Racetronix site.

 

To test your E85...just FYI

be nice if some of the mail order tuners could offer a e85 tune

 

Somethings to consider...good read.

Does anyone know if I can possibly run e85 with #42 or bigger injectors and a stock fuel pump?

 

Yes, NA you are good to go. Make sure your pump is not falling off in the higher RPMs.

 

How can I tell? Can I use hp tuners to check? How far can I use the stock pump?

 

An AFR gage will be a good indicator if fuel starts to drop off. Honestley, for peace of mind wait until you upgrade your pump or get the racetronix wire harness.
The best way to tell is with a fuel pressure gage, get an extension to run it under the hood onto the windshield and take it for a spin.

 

Be careful here friend, methanol and ethanol are not the same and you will not be able to mix methanol with gasoline in any % you want. Methanol and Ethanol are both alcohols but only ethanol is fully miscible with gas in any % if its dry enough (no excess moisture).
Methanol will drop out solution above 10% and you will need a blending agent to keep it mixed. Methanol is more corrosive.

You can use HP Tuners or anything that gives you injector duty cycle and LTFT's (long term fuel trims). The e85 will need more fuel for stoichiometric and that will show up in your LTFT's which will go higher as you add ethanol. If you have adjusted the tune for the bigger injectors then they will have the capability to provide the volume necessary BUT if you are running out of fuel pump capacity they will still trying to provide enough fuel without enough fuel volume from the pump, the result is still insufficient fuel.
I don't believe this will be an issue just for using e85 unless you are up in HP. My Z06 I run the stock fuel pump with a fuel pump hot wire and IDC 1000 injectors and it works very well on E85 with only 28-30% IDC at top rpm's. The same setup with stock injectors would run 88-94 IDC on gas and would not allow enough fuel volume for much ethanol %. My Z06 is near stock with only a CAI and Corsa exhaust. You wont save any MPG $ on running e85 but it's beautiful high performance fuel and cheap for race fuel.
As you add ethanol the amount of fueling needs to be richened in the tune or it will run lean.
My truck can run more ethanol with stock injectors but it's because it does not see higher rpm's. The OEM's do not give you much excess injector
on gas vehicles.

Hope this helps.

 

Ok thanks for the reply, I will have to check my IDC and report back. I'm only using e85 as race gas and right now I have a mix of e85 and 91 octane but I haven't checked my LTFT's. I will be sure to do that

 

Where are the cranking tables on hp tuners and what does OLFA stand for? Runn posted about these under the "how to" on page 1. Also how much more timing do u run than stock? 4-5 degrees?

Cranking tables
On my Vette engine/fuelcontrol/general.

Timing is an area I have not fully optimized yet on my Vette. Some areas may take more timing but I am not sure it's worth much since it's mainly my DD.
I use to run a drag only Anglia gasser BBC on methanol and in that car 38 total was what it liked. I tried going higher but neither et's or mph where better.
LSX heads are more efficient and may need less timing. I would suggest not take a 3-4 degree across the board approach, maybe add 1-2 degrees at a time, and only in the RPM cyl air mass range you are going to be in. Others may differ I don't believe in taking timing to the raged edge for most racing these days.

 

Ok thanks
