Noisemaker for those who dont know:

That weak clip - holding the noise part in place - comes loose - was causing complaints from drivers that a vacuum leak appears.
For the intercooler - are you referring to the MISHIMOTO UNIVERSAL RACE EDITION INTERCOOLER J-LINE?

Is this the intercooler you speak of? MISHIMOTO UNIVERSAL RACE EDITION INTERCOOLER J-LINE
Like I said I never had an issue with the noisemaker/Helmholtz resonator. I did have the throttle body cover pop off due to boost and it is a common problem unless you have the revised TB motor.
Whichever aftermarket intercooler is advertised for the SHO. When I had the SHO there weren't any options so I made do with the stock intercooler.
Again you're not running over 18 psi boost on the stock Garretts. If you are, you're doing it wrong.
I read through the guide, and several posts and threads. Here is whats up, i have 2012 SHO and I have not read it out yet. Before I go ahead and start tuning this car I am trying to wrap my head around the logic in the PCM even at a high level.
So what I get as just a general flow:
Driver depresses accelerator and the Accelerator position is used to determine a desired torque from desired torque table.
The PCM then Converts the Desired torque into a desired airflow (Unsure where this happens, possibly in the torque model torque calculation tables)
At some point the desired airflow results in a Desired Throttle inlet pressure and throttle angle (also unsure where this happens)
The desired throttle inlet pressure and engine RPM are used to look up a WGDC.
I definitely feel like there's some key tables I would like to see not visible to me.
The 2010-2012 SHO strategy is different from the 2013-2019 SHO. I wouldn't be surprised if HP Tuners didn't define a lot of parameters based on what I have heard from other owners. They've pretty much put a lot of these vehicles to the wayside for parameters as they focus on the higher priority projects. I have been waiting on some stuff for my 2018 Explorer to be defined and gave up hope. I sold the vehicle so my care factor is zero at this point.
Is there a difference in the stock file of the Ford Explorer ST 2020 within the same model, especially in the Trans? I have two files, one of which is different from the other, mine has a date 11/19, which is correct???!!!!please help me
StockFile - 2020 Explorer ST.hpt
2020 Ford Explorer ST Stock - 20210930, SRBM4BA.hpt

Metroplex I know you sold your vehicle a while back but I appreciate the work you put in and shared with us!
Oh yeah! You have greatly benefited a LOT of us!
Thank you for the great info @metroplex !
2019 F-150 3.5 EcoBoost 4x4
Just got an explorer sport to start playing with and tuning, this has saved me and incredible amount of time and testing, THANK YOU!
I haven't checked this thread in awhile but am glad to see this guide has benefited so many!
I have been meaning to produce a guide for the "2nd gen" EcoBoosts (basically 15-17 trucks/Fusion before they switched to split injection on the trucks) but it has been years and I never got around to it.
I think we could combine our experience and come up with a pretty good guide, I have the 6F55 dialed in pretty good now. Engine side of things I've really come up with some good files that produce really nice power, some could be considered a bit on the edge.
Open source it, could do a moderated open Google doc.
I did that years ago for my GM Global A CANbus message spread sheet and it worked out pretty well for that.
I could write a pretty in depth guide, would take some time to do is all, there's a lot to cover.
That would be awesome to have a few more examples and information to work off of. I've been reading and reviewing data the last week trying to wrap my head around tuning these engines. nearly all of my experience is with older ford 4.0, 4.6, and 5.4 (2 and 3 valve) engines. Moving from those (*simplistic*) parameters to these is a pretty big jump.
I do have a question that hopefully doesn't make me seem too ignorant: I see the tune file I pulled from my explorer has 0-5 different tables for "mapped points" for spark, torque management, speed density, ETC.
What are mapped points and what in the tune switches from one point to the other?
So, comparing the Guide which was originally written for a 2014 SHO against my 2018 explorer (3.5 EcoBoost) I can see some things have changed in the software and tune from 2017 to no2 (summer 2024). I have attached a channel and layout configuration for the EcoBoost based on the guide's recommended channels plus a few that I can see being helpful.
As I continue to tune my explorer I will update these files and add findings to this thread (which is already the most helpful thread on this forum for EcoBoost).
Also for those unaware of "mapped points", Eric has a video and thread that explains it quite well. the link below should lead you to it.

Here is a base tune for the gen 2 EcoBoost (from a 2018 3.5 explorer sport) I've completed modification of all the limiters and nuances as outlined in the guide, however I'm Calling this a "base tune" because I left ignition tables, driver demand tables, and shift scheduling stock.
Theoretically at this point increasing the driver demand should directly correlate to higher boost, more fuel, and therefore more power.
Ignition timing will vastly change from setup to setup depending on the fuel you run, locality/climate, and other factors to use the guide (and common sense) to tailor this to your own needs.
Shift scheduling will also be based on your given setup. I will most likely run close to metroplex's recommendations eventually but want to do some intermediate datalogging as I go.
*edit, i found a few discrepancies in my tune. corrected them and reloaded the tune below. Note: sport mode DD table has been updated in this tune.

Here's a quick log I did this morning.
It seems that torque is being reduced and the throttle angle is limiting potential, but overall runs well and definitely faster than stock.
Any help or input it greatly appreciated. My current thoughts are that I see "Traction control" as the torque source and "torque control" as the throttle angle source but not 100% sure where to start making changes without extensive testing. Alternatively, it may be that I did not have traction control turned off and the vehicle was sensing slip at the wheels?
@metroplex (or anyone who knows), On page 16 of your guide it states:
"This is another very important set of tables. This one had me hitting a roadblock for about 2 weeks before someone was willing to share knowledge and I found out
#5-7 was the root cause for me hitting a torque limiter."
your are referencing tables for transmission>Torque management>rate limiting> upper limit (6), Multiplier (5), and ramp time (7) however do not provide recommendations or an explanation of how to understand these tables. Any further clarification would be a huge help!
Cheers,

Update:
After a ton of reading about limit sources, LSPI, and reviewing tunes from other members, I have come up with this tune. It definitely requires some refinement, and the boost gets a spike little on the high side at 19psi under WOT and high RPM for extended periods of time. But it runs STRONG compared to stock tune.
With ambient temp around 100F and intake at 125F my IATs are spiking to nearly 190F during a WOT pull in 4th gear!!! I've already ordered a mishimoto intercooler to fabricate into the front end and will be doing some additional mods to increase airflow through the cooler, but as it stands the high IAT is pulling 7 degrees from knock retard with the 91oct fuel I'm running right now.
something else I noticed is that in 1st and 2nd gear boost hangs out around 14 but as soon as it shifts into 3rd -BAM- full boost at 17.5ish. I didn't have traction control turned off during this pull so that might have something to do with it.
To build this tune i took the base tune i generated from the tuning guide and then reviewed a few real world SHO tunes (one of which was an E30 tune, and yes i was conscious of the differences in stoich and other fueling changes from E10 blend here in AZ and E30. I left those changes out of this tune). I then did a lot of reading about LSPI, duty cycle, sources and limiters to find blend the tune with "safer" low end daily driving loads.
In normal driving mode the driver demand is stock and it drives very much like a stock car with added responsiveness. Drop the shifter into sport mode and BAM full use of boost and power.
Some other misc info: when stock I was maxing out around 24 MPG under sustained cruise at 65mph, with this tune driving the same flat/straight road at the same speed i now get 26.7mpg. Personally I'm a bit shocked by this and find it too good to be true, but 2 separate tests on different days yielded similar results. With more testing and refinement, I'd love to bring that to 27.0mpg.
Any input or links to more reading is appreciated. I'll update as i learn more. at some point I'd like to put everything i learned into one place to add to the current guide.
Cheers,
-Nick
