Hmm okay. Just so bizarre it would run so lean like that, especially with PI.

My only other guess would be a tuning issue or injectors

That really sucks. Wish you best of luck with moving forward, if you need a new motor I believe there is an ongoing thread, I believe OP said they managed to snag a 67k mi motor. May be worth checking their supplier. Also not sure if you're aware (I only recently realized this) but for any future tuning you can setup alerts on MHD. I have mine set to alert me if STFT hit +/- 25 when WOT.

Thank you man will definitely add that alert to sfts on the new motor, will look into that thread Forsure was planning to rebuild because my motor only had 50k on it but might just go with a more cost effective engine replacement

Why are you saying it was running lean? From what I can tell...the logs are showing AFR's in the 11.8-12.2 range. If anything, that is rich/safe side for an e85 fuel mix. Definitely not something that should have you any issues and hurt a motor.

It's probably shitty ass tune at this point. Even if your injectors were leaky a bit before I don't see how they would suddenly exacerbate and blow your engine. This is why I stick with the MHD OTS map personally...

Wish you best of luck, sucks to hear.

Yeah....because an OTS tune that's made for a stock motor with stock turbos is going to be much better than full custom tune on a car running bigger turbos and a PI setup running straight e85

Good lord......

I'm saying it was running lean because trims are maxed in the positive end, meaning it was adding all the fuel it could to maintain those AFRs. I guess saying it was running lean is a little incorrect, but it would have been lean had the trims not requested more fuel.

Ah...ok, I see what you are saying. Yes, those trims were maxed out.....but the end result was still a safe mixture that shouldn't have hurt the motor. Something was wrong.....but the fuel mixture isn't what cooked the motor.

Too me it looks like there where a whole bunch of timing corrections....and that's not good.

I can agree on that. My first thought is, E85 mixture. OP says full E85, but i'm wondering what % actually came out of the pump. We're hitting the colder months here in MD, and I know what's coming out of the pumps is definitely less than E85. That's the main reason I decided to wait for spring to tune on even just an E50 mixture.

I was thinking that to but just want to hear what other have to input

[iqraceworks]

Did you test the ethanol level of the e85 coming out of your pump? It can vary all over the place... especially in fall/winter. If you got a low ethanol mix, that could have caused the timing Correy, and that could have hurt something in the motor.

What's the history of the car? Did you just buy it, or have you had it awhile? Never underestimate the fact that there are plenty of people there that have no issues with selling people a used car with known issues.......

I've tested the e85 in my area as I am in socal and e85 is provided by Pearson fuel which I tested to be true e85

I'd guess it was good then. I've heard Pearson always has good E85 at their pumps.

I've owned this car for a year and 4 months and bought it with 39k and I put about 12k miles on it and I did everything to it myself no shop or mechanic has done work on my car but me, car had its oil changed with liqui moly 5-40 every 3k with Mann filter and warmed up to 200 before every stepping on it

Did you check the ethanol content in the e85? The log doesn't indicates anything that might hurt the motor.....except timing corrections, and that could be caused by crummy fuel


Also....your turbos look kind of worn out, or you have boost solenoid and/or wastegate issues. You are 4-5psi under your boost targets.

Turbos are 17t eBay I'm thinking maybe shitty actuators or bad wastegates but I tested them and they fully close at 7hg, and fuel has been tested true e85 used an Amazon tester pouring water and e85 and it came out good I have a pic but can't find it

Good lord......

thats not even what i said buddy, what im saying is theres a bunch of tuners who've blown up enough motors... relax

What did it test out at? The e85 in my area tests at 70%...and that's what it says at the pump also.

It was right on the line e85%maybe e82-84

I quoted exactly what you said. You said you stick with OTS tunes. Well, you can't do that when you have bigger turbos and a PI setup.

Well....that's strange.

The fuel trim issue is odd. What did Ken say about that? With a PI setup, your fuel trims shouldn't be maxed out like that......on the other hand, the end result and AFR's look plenty safe.

Sometimes stuff just breaks.....bad luck I guess. Ken has been doing tunes for a long time, he helped develop all of the MHD tunes...so he knows what he's doing.
