There are tables in the Ecoboost tunes for adjusting the lambda and other items for E-content. The programming in the tune is not active from the factory however, so it will not compensate for ethanol content on its own. You can turn it on in HP tuners. Thats how there are companies now tuning for anything from 85 octane to full E85 on a single tune.
I missed this earlier, what table(s) are you referring to? I would like to look into it. I saw a flex fuel tab in there but I thought that would not work on non flex fuel vehicles. How could that work on our trucks if there is no sensor that can communicate with the PCM? I manually change the stoich value for e50 and that was pretty much it....and this has to be changed with every 10% change in E content.

Edit-the only table im seeing is engine>fuel>power enrichment>wot lamda FFV. iT says "when flex fuel logic enabled it will reference here" I dont see any flex fuel enable option. The other table I see is just for FFV HPFP pressures.....so maybe none of this is enabled on my PCM?

I guess @Blown F-150 did mention an auto octane tune he has.

If you’re hitting the spark source for boarder line knock. Then your cap is limiting the timing.

If your hitting the spark source for MBT, than you’re hitting the MBT set in your tune. You can always compare your tune to a stock one (I can in SCT anyway) and you’ll see if those limits were lifted.

@mass-hole @Blown F-150 I checked the log last night and confirmed my thoughts, that if it was allowing the spark, then the limit is not hit. The spark source was pre ignition the whole time, no MBT was referenced. SO MBT limit is not currently being reached. I probably won't go over 16 degrees until I confirm on dyno.

Tuner just set a more "aggressive" timing map over that I will test tomorrow. As I said, I only upped timing on WOT, so the rest of table was adjusted.
 
how many miles did it take you to get that much fluid?
2000 +/- caught nothing first 3500 or so, then in cleaned out the can with some crazy aerosol degreaser... it was used and now I can hear the difference when the boost is pulling vacuum. I suspect the latest contents’ volume could be due to the temperature dropping around here and leading to additional condensation, though there didn’t seem to be much water

Sorry, 12th gens do not have it. 13th gens do. I haven’t actually looked at the 2015-2016 tune but for sure the 2018 tune has a toggle for inferring ethanol

I bet its in the 12th gens somewhere but, like we discussed, HPtuners just has not put a ton of effort into it.

Has anyone experienced permanent timing chain clanging? The engine is fully warm. 😭

How do I copy a video over from my laptop or does it have to be hosted on a website?

It won't let me post video on here. Anyways, my post above was sarcastic. My motor let go. I was carrying 20psi and 15 degrees of timing on e50 as I discussed. The log file was SPOTLESS. Fuel pressure fine, zero knock, not leaning out etc. Just the stock parts could not handle it. I would suggest not running higher timing on stock stuff.....even on e85. If you want to really push it, keep adding boost and keep timing 10 or lower. I thought I was still in the safe zone, just really close to the limit but I hit that limit. Hard lesson to learn.

What happened I was out doing some data logging. I did a few pulls and it was running hard...and I mean i could tell. These trucks are slow, but with 20psi and the 15 timing, it was PULLING. On GT turbos 19psi and 10 degrees of timing, it makes 450hp peak. So on myself on 20/15, it was between 475-500 probably.

FYI Truck has 60k on it and this tune with the upped timing on e50 was only ran for 2 weekends. I made probaby 10 hits total on this tune. SO at the limit, it aint going to last long.

I did two hits and then pulled over and checked log, all good. Went out to hit 2nd gear. As it was up in 2nd gear and going into 3rd, the engine light started flashing. I let off the gas right away and then light continued to flash a few times and then it stopped. I was well damn, that's not good lets hope there is no noise! The dash light flashed a handfull of times for 5 seconds or so and then shut off as Im still driving. As i exit the road, hoping no noise, i roll the window down and can hear a noise...o no. The cluster was still showing oil pressure. Drove up into a parking lot and killed it. Pop the hood, nothing leaking etc. Start it with hood up and it banging hard...sounds like rod knock..95% it is. I think it killed a rod bearing or bent the rod or both. It didnt window the block though! I checked DTCs and it had stored a code for "cylinder 2 misfire pending". Thinking when the bearing/rod went, it started firing weird, so threw the code and when I let off the throttle it was firing normal again.

I thought at first it might be an issue with the new trans I just put in, but it is loud banging with RPM and sounds like rod knock. Plus, since it threw code for cylinder two misfire, I cant imagine it would not be the engine.

So at that point I talked to a few people and decided just to limp it home since I was only 4 miles away and it still had oil pressure. I went slow the whole way in 4th to keep load light and it made it home.

RIght now, I am just hoping not a lot of metal, if bearing failed, made it to turbos.

Was supposed to go to the track tomorrow and run 12 finally, but that ain't happening! If it had to fail, I am glad it failed close to house and not 100miles away at track.
 
Sorry man, i hope its not the motor. Ive heard of a similar sound happening when torque converter bolts back out.

When my jeep engine started knocking it was bad but the rod never fully let go until after i rebuilt the head and tried to start it for the first time.Thats when it fully let loose and came through the block.

Here's to hoping it's that Torque Converter instead. [emoji1696]

Again, as I mentioned in my post, i thought that could be too and other people mentioned it, because the transmission and converter was just put in. So I was thinking could converter bolt back out or fly wheel bolt back out? BUT It has been in for about 1000miles, a trip to the drag trip and multiple data log wot pulls. I can't imagine a bolt now just backing out. If that was going to happen, it would have happened immediately IMO.

To get further into the transmission details, if a flex plate bolt backed out, it would be hitting the front of the converter and making a consistent grinding noise. IF a converter bolt were to back out, same type of noise. This noise sounds just like rod knock. It sounds like it is consistent with piston moving and is louder from top of engine.

Finally, the code stored in PCM is P0302, which is cylinder 2 misfire detected. I believe this is the final nail in the coffin. Both HPtuner and SCT read the exact same code. If it was just a noise with no code, I would immediately check the transmission. However, with this code stored for cylinder 2, I do not think there is anyway if a transmission bolt backed out, it would have caused a cylinder 2 misfire specifically. I would also think, this would cause some kinda of vibration driving. I drove it home 4 miles as i said and i noticed no vibrations or issue shifting.

Does everyone agree with that assessment?
 
Well crap! What a unfortunate situation. I think with the info provided, you are likely looking at a motor. However, for the effort, I would be checking a couple things to verify.
  • Pull the starter and the access plug to verify all the TC bolts are there and tight
  • Send out for oil analysis. I'm guessing you either bent a rod or cracked a piston skirt.
  • I would even go as far as dropping the oil pan.

I was "tricked" by rod knock as well. I swore up and down that the motor had a issue, but it turned out to be the Torque Converter.
 
Yea im hoping he tears in to the motor to confirm the issue. Definitely interested in hearing the verdict.

My plan now is to get a OEM long block, put a real conservative tune on it and drive it until the wheels fall off. With this engine, Ill have a new engine and transmission now, so basically a new vehicle as long as the electronics hold up 😆 THe new engine is only a little bit more money than a used engine from salvage yard, so that is why I am choosing new.

I will also be getting all new gaskets etc where I can see I would need them. Trying to see if I can get new o rings for the injectors or if I should just order new injectors.

I thought about a built motor, but then Ill just want bigger turbos, injectors and it will never end. This is a daily driver. If I want something fast fast, I spend the money on building a mustang or something of the nature....you get the point.

The motor from Ford is supposed to be a new motor and not a reman. It is supposed to be a 15/16 engine, so it has updated parts vs mine.

I will definitely at least take the pan off to inspect everything before sending the motor back for core charge. The work wont be happening until the first week of January. My friend with lift, is out of town during December and for Christmas, I will be paying him to do swap over a weekend. Wish I didnt have to wait a month, but it is what it is.

I was so unmotivated this past weekend to look at it. This weekend I may just pull the oil filter off and cut it open, see if there is metal in it.

2020! o_O
 
why not pull the starter just to make sure your not spending money on something you dont need? I mean i know your pretty confident in cylinder 2 being damage. But would be nice to know there isnt some other issue.

So true. But..... You do realize that you have spent considerable money and time doing exactly that already? [emoji3]

And no offense, but the cost of that new longblock COUNTS against the cost of trying to make your truck go fast.

None of which I would condemn or judge anyone for. It's what we do.

I think ill pull oil filter this weekend and starter. Unless I see metal in the oil filter, then no need to pull starter. Ill order a motorcraft filter and couple quarts of syn blend because I am still have to going to start it to move it to tow truck.

Ya, I will no longer go towards running fast. On a safe tune it should be 13.5 probably and Im just going to leave it alone...for now. Maybe in a few years I'll build an actual engine for it. you have to understand, even with a built motor and maxing out my fuel, it will still only be a 12 second truck. It's too much money to spend for not going fast.

Im probbaly going to put stock HPFP back on and sell this XDI one when motor swap done, Ill recop a little there.

FYI I also was informed the engine is 3 yr/unlimited mileage warraty, covering parts only because dealer not installing it.

I can also send it back, paying shipping, if I dont use it. (y)

This is what I mean by FAST. You will never see a ecoboost do this. I dont think you know how fast a C6 zr1 with 850 hp. That car weighs around 3200 lbs.....
