Blend the E98 with the pump supreme. Ethanol targets are hit everytime. E98 has tested the same from every jug. Winter pump E85 I've seen as low as E58. Usually E60-E75. Still, too variable. Do some google sleuthing in your area. If you can access it in your area, snag some up. You won't regret it....unless you love the syringe and test vial!

Well you have hit the nail on the head if it for sure a bad case of low content ETH then this failure is not due to the tuner or the original poster or tune, it's unfortunate that the car was tuned for e85 octane with certain timing and target AFR's, like tuning your car for race gas than you decide to run it on pump with the same tune, any tuners car will get hurt. it's unfortunate but this is maybe a lesson for everybody to be more vigilant and aware of the eth percentage when they fill up. I sincerely hope this is not the case again hope it's a simple fix! Last edited by whoop_ass; 01-18-2018 at 10:46 AM.. |

I'll just leave this here...
Summer Blend: Class 1 (min 79% ethanol) Spring/Fall Blend: Class 2 (min 74% ethanol) Winter Blend: Class 3 (min 70% ethanol) Same Blend the WR was made. |

I always gas up at Meijer. In the Midwest they seem to keep summer blends the longest. I tested into November and still was over 82% ethanol. Summer months all my readings have been at or above 85%.
I will have to keep my eye out for 98% though. |

OK WOW!!
thanks for posting the logs, and anybody that understands a motor and the S55 can see from the logs that it def not tune related at all. at that boost pressure and timing we can even factor in that this car with this tune could even get away e40 and the DME would have no problem keeping things in check, this tune is def not a ragged edge as 1 of the above posters mentioned. Clean timing and Cylinder 1 always has zero timing correction, and that is the cylinder with the problem, honestly my car is running e60 way way more boost and timing than this log. The CS map runs almost the same boost up-top maybe a psi less with 14 deg as I mentioned, even the AFR's are not that Lean to cause any damage. Tune is def on the conservative side if you have to ask me! Last edited by whoop_ass; 01-18-2018 at 10:17 PM.. |

Update on the car, cyl 1 and cyl 3 injectors are being replaced along with the bank 1 turbo. The tech suspects the leaking injectors caused the turbo to go. It was definitely not tune related however, running e85 for the last 6k miles might have caused this. Anyone else out there run into injector issues while running e85?

Btw, what do you mean cylinder 1 is being replaced? You mean bored and sleeved? Did you run your car with a full tank of pump gas every now and then, or were you running E85 only for the past 6 months?

That makes more sense lol. I read it as cylinder 1 + a total of 3 injectors needing replacement. Not good to be reading this early in the morning

Makes complete sense now and of course this wasn’t engine damage. Bad injector causing turbo to go! It happens on stock cars on 91 never ever modified. My brother sees them at the dealer every here and there. Apparently N63 V8 they have seen the most for them.

I've run a little over 6K miles on E85. No injector issues, at least not yet. I ran a tank of 93 around 4K and now switched to 93 again for winter.
Hopefully this is just a rare instance. With the higher ethanol content of even regular pump gas most components are built to handle ethanol nowadays. |

So how can you prevent the injectors from leaking? What causes it to leak?

This doesn't make sense....
Leaky injectors and a blown turbo doesn't explain oil in only one cylinder. Cylinder #3's plug would have been wet-fouled and here it looked clean. Also, veryyyyyyyy ODD that two injectors fail at the identical same time. Something doesn't add up here. |
