Running E85 in the stinger?

[General_Vodka]

Now my check engine light is on 0171 code...

9 g of e85? That's too much, the limit is 4.2 - 5.

Yep which is why I said I effed up

Keep adding 93 to it after each decently long drive. Maybe every 50 miles so it breaks up the percentage of ethanol. What is the code description?

Good idea. I’m at half tank now so I’ll fill her up tomorrow. I have two codes now 0171 and 0174. Jb4 doesn’t provide a description but I Googled it and found Fuel Trim System Lean Bank 1 and 2.

The fuel system cant keep up, so the Jb4 will keep going into limp mode with a lean code. You should probably put the jb4 back on map 0 also. With less commanded boost and power, the fuel system may actually keep up.

Yea that’s the first thing I did after panicking. E85 gauge on JB4 is now showing 35 after filling half tank of 93. I would think the codes will be going away soon since 35 is around where it’s at when I run 4 gal of e85. Fingers crossed?

Update: check engine light is off but jb4 is still showing the two codes

I run jb4 map 5 for my dd. 5 gallons e85 and the rest 91octane. When I first did it I noticed the power difference after driving so many miles. If since then I never went back to just 91.

Have you had any issues long term with your fuel lines running E30 mixture?

Not sure if anyone has mentioned this, but I read the jb4 is developing a flex sensor add-on. Not sure it is available yet, but I suspect it is meant to solve this type of problem.

I know Burger came out with their CPI kit add on to the Flex Fuel kit but they said that still doesn’t allow for running full e85, only a higher mixer.

I recently gave E85 a try and added only 2.6 gallons of it and noticed a little bit of a difference. To get true E30 mix I would need to add close to 5 gallons of E85. I was wondering if anyone else has tried this?

just put 5.5 of e85 and the rest 91 full tank and wow way better in map3

 

[Brennan]

I agree. I run 4-5 gal e85 with 93 oct on map 3. It’s amazing

I’ve finally been on a lucky streak of no over boost and no codes bc I finally gave into logic and toyed with less E85. Maybe using the same gas station too for E85 helps, or not. I know those EWG add on connectors along with me finally figuring out the right FF number for my JB4 settings has helped. I feel like all my aftermarket pipes makes this a more delicate balancing act, but always worth it bc of the drive.

For all my RWD Stingers out there, we all know each other’s pain of over-boost. But we make up for it with those fun pulls once we’re off…well, assuming no bumps again…

Yes try and way better power wouldn’t do above 5.5 tho highest ever went and feels good

I easily run E30 on map 4, runs great. Best time so far is 12.05 in 1/4 mile
I have since added WMI, hope to get into the 11's next time at the track.
