All the pumps around where I live have 10% ethanol fuel. Do I need to disconect the wire on the computer? Just got to thinking today and I really dont know. 06 M7/06 M5. Thanks for any input...
ethanol plug

Yes, Unplug it.
unplugging that wire adds a 3% fuel curve to compensate for the ethanol. if you find regular gas, run it and don't look back. but be sure to plug the wire back in or you will be "running fat".
Yes, a picture would help too.
I go my SLP Performance Edition Kit back with a preprogramed Power Commander III. I see in the instructions it says:
"Fuel Map Requirements
- For non Ethanol Fuels: use pre-programmed fuel map SLP Part #70-201.
- For 10% Ethanol Fuels: Set high RPM fuel button on the unit to +3 bars (+6% fuel).
See PC III insturctions for adjustment procedure.
Never use fuels containing more than 10% ethanol".
My question is, it doesn't say anyhting about unplugging a wire anywhere. I wonder if you do that in addition to adding more fuel?

never touched it
Have 05 m7 and have never touched it.Friend has 07 m6 never used it either .I know the 05 is rich anyway.check your plugs to be sure like manual says may cause engine damage..JMO..

Its a single wire plug right at the ecu. But not sure they have it after 06.
i can't find a pic of it for the life of me. i believe its right by your ecu. i think there is even a little caption telling you to unplug it for ethanol and plug it back in for regular fuel.
My dealer said the newer sleds have a sensor so there is no wire to disconnect on the 09. I have 2 05's and 2 09's. The 05's have to be disconnected if you run ethanol however the pumps say 10% just incase they still have some ethanol left in the tank. It is my understanding that around here (Boise ID) the ethanol plants have gone out of business so it is likely that there is no ethanol although the pump says so. That is just what I have heard.
Here's some information on the topic that I copied off the internet. So, the validity of the below information is in question.
I live in Washington and drive a Jeep Grand Cherokee every day back and forth to work. I was getting 20.5 to 21 MPG and now I am getting 18.5 to 19.5 MPG. I quite certain we are suffering through ethanol based fuels again. How can using 10-20% more fuel be good for the environment?
Feb. 11--BOISE, Idaho -- A Senate committee narrowly rejected a bill Thursday requiring all gasoline in Idaho to contain 10 percent ethanol.
With the Senate Transportation Committee split 4-4 on what to do with SB 1004, Sen. Bert Marley, D-Pocatello, cast a no vote.
"There are some questions that I need answered before I could vote for this," Marley told the committee and a room packed full of onlookers.
The bill, backed by the Idaho Farm Bureau, would have required all gasoline sold in Idaho to be at least 10 percent ethanol by 2010.

The state of washington has mandated that gasoline sold in the state be blended with ethanol. major oil companies are transitioning their gasoline to a 10% ethanol blend. this started on april 1, and will be completed by june 1, 2008. be aware that ethanol-blended fuels may cause sediments to mix with the fuel resulting in plugged filters. additionally the presence of water on the bottom of your tank may reduce the oxygenate content and the octane rating. be careful buying fuel at these cut rate stores, they may not have changed out there filters to the pumps.

AND it makes your vehicle get worse mileage so you have to buy more gas.
Glad I work in CDL

Posts: 975 ...all the pumps i've been to here in CDA say up to 10% .....and i think they are running that much
Once again, please read with a grain of salt.

Be careful with the ethanol it has a very weak bond with gasoline then when it separates it all goes to the bottom bonds with what water is in your tank and thats right where your fuel pickup is.

Yep ... I fried a mod 99' 700 top end when ethanol first became popular at the pump. Same with most fuel injection cleaners & anti-ice additives.
Is there any additive we need to add to the tanks of gas to offset the Ethanol ? Or just ride! I am not worried on my sled as I have a BD box and gauges to richen up if need be - I am thinking on my wifes M8 where I am just running a BDX intake / SLP pipe.
i believe there isn't any gas stations that sell non ethanol in washington however there are places, suppliers that will sell non ethanol to you in bulk for purpose of marine and farming. im sure glad im in id we still have the good stuff for one my vehicle mileage is a lot better. its better on your small engines 2 strokes. ethanol has a shorter shelf life,will get gummy,varnish in carbs fuel lines and tanks and low flash point over time not to mention rusting metal tanks even pulling moisture from air
Nothing new is it?
Gas companies have been adding ethanol for years right, like from Oct through April or something? Dont they do it so that it attaches to water in your tank and then the water gets burned and eliminated from your tank? I remember back in the old days, people would say to always keep your tank full in the winter so condensation does not form and then drop into your tank, sink to the bottom and then freeze when its going through the fuel line. You never hear of that now. I know that like Frostbite, my gas mileage on my F250 7.5 liter gas engine RECENTLY went from fairly reasonable 13-14 mpg on the highway to 10 at best (ouch). I think the ethanol hurts big engines' gas mileage more than smaller vehicles, at least that is what I am finding.
