Yes, you can adjust the speed limiter with Hp Tuners.
Definitely time to do a boost leak test. There are a ton of How-To videos online on making them pretty cheap. I suggest going 1.5 times your intended boost pressure and spraying the couplers or any...
Ya I think there are some pretty significant differences between the gen 1 and gen 2 3.5s. The guys over on the Ecoboost forum would probably be able to give more input on those exact differences,...
It's unlikely you will have enough injector/fuel pump to go to full E85.
You should be able to use the flex logic from one of the other Ford flex vehicles of the same year to populate those...
I would be happy to flow them in my bench to see how they pan out.
It's been 1 day and this is not a very active area of the forum. Check under the engine diagnostics tab and see if there is anything under the codes for airflow. You can probably just max those out...
There is a limiter that forced enleanment to reduce torque that is time based on some of the Ecoboost stuff. I had this issue with my '13 3.5, but I can't remember exactly what the parameter is.
How close are you to running out of MAF with it in a 3" tube? I ran into some issues a while back with a 3" charge pipe setup where no matter what we did it would cut out at a certain load point,...
That's pretty interesting... I'll check pricing on one with my local Ford guy. I would love to switch my 2013 over to straight E85.
Welcome, Dave. There are a couple guides on how the Ecoboost platform works. The '18 trucks seem to handle quit a bit of power and in most cases as long as you can run good fuel you can get well into...
Best bet would be to compare the 2 strategies and see what the differences are.
These values are all inferred based on a pair of tables in the next page over in the tune. I disable them both with no issues.
The OS will target stoich no matter what that may be for the fuel you're running. The stoich value in the tune is just for the fuel volume calculations and doesn't change the actual target. For...
A good start would be to read the guide put together by Metroplex. It's based around the 3.5, but the principals are the same.
Would you care to elaborate?
What are you altering for catless downpipes? I have some on my 13 EB F150 and without changes to my tune I noticed a good increase in power up top, even at the same boost pressure.
The "Stoich" value is just purely for fuel volume calculations. The closed loop system works off Lambda so the stoich value of the fuel is irrelevant aside from the fuel calcs.
Not sure if there...
Considering the '15 is still direct injection only, you will be looking at a HPFP upgrade if you want to consider E85. I would suggest just running E30 personally. You can stretch the factory fuel...
You need to see what your fueling source is. I would imagine it's "Stoich". Guessing you are trying to improve your fuel mileage by leaning out your cruising afr?
The thing with tuning newer Ford stuff is that you're just trying to find what limiter you're hitting and manipulating torque request tables. You will get better advice on here from posting a log...
Ya the specific table I'm talking about is ambient temp vs coolant temp, but the axis on either is unable to be changed.
No, that is controlled through the BCM. You could likely do it through ForScan though.
One issue I see with going to a cool thermostat like the OP is running is that, at least on my OS, I am unable to alter the temperature scale for when the fans kick on, and the lowest temp is like...
Looks a little backwards from what I typically see them like. I typically pull a little timing around peak torque and then feed it back in as rpm increases. You have peak timing around peak torque...
