on that e85!

 

bumbbbbbb!!!!

 

Call up your tuner and tell him you need your car checked out again ASAP. While you wait to get your car checked out, DO NOT GO INTO BOOST. DO NOT GIVE THE CAR MORE THAN 50% THROTTLE. BABY THE CAR.

 

greaaaatttttt!!!!!!!!

 

Did you make sure it was truly e85?

 

Either you wideband took a **** or your lean as all hell, you should be 12.0 and richer in boost..... 14.0 and you will destroy stuff pretty quickly.

 

yeahh it is

 

i'll call them today and see what they say!

 

If your gauge is staying constant all the time, whether it be lean or whatever, it's probably not the gauge. My wideband is screwed and shows crazy readings if any at all. Call your tuner, man...
Be a shame to murder that motor, cause it sounds pretty sick...

 

could be tuned correctly but instead of E85 the station sold you E98.... that will make you a good bit leaner too, not sure if it will make you 2 points leaner.

I know when I went from E70 to E85 on the E70 tune I was a shitload leaner, definately enough to destroy the motor, this is the biggest risk when running Ethanol w/o some sort of Content Meter or a Flex capable EMS, you just hope the station is selling what they say they are.

 

i called them today..dropping the car off on monday we keep u guys posted.....i get the e85 from krogers idk how it would be messed up....they said it might just be a bad o2 sensor or somthin....ahhhhh mannnnnnnnn!!!!!!

 

Doesnt matter who you buy it from, Ethanol is not nearly as tightly regulated as Gasoline is, at any given time your blend could be E50 all the way through E98.....

They use Gasoline to make the blend, if gas is getting expensive instead of using alot of it to blend down the E98 they may decide to use none and just sell the Ethanol the way it is with no Gas added to make it E85, more money in their pockets.

 

iccc

 

And vice versa, if Corn Prices are up and Gasoline is cheap.... your more likely to get an E70ish blend if you get where I am going with this.....

Hopefully its just the fuel and not something else, might want to look into a Content Meter so you know whats in your tank at all times, small investment that will save your motor.

 

yeah i was just looking at it!

 

I would take the sensor out and free air calibrate it. plug it back in and see what you get. How old is the sensor and what brand are you using. I would say its the sensor or your tuner forgot you were using e85 and tuned for 93octane.

 

Why would this matter? Wideband's dont care what fuel you use they do the lambda conversion and show normal gasoline readings on the gauge, I am tuned to 11.6 AFR using E85 because the wideband converts it.
