    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?

    I see there might be an aftermarket intercooler option for the SHO which I'd recommend. That being said, the stock intercooler on the SHO seems to be more effective than the stock one on my Fusion Sport.
    Noise maker for those that don't know what it is - I didnt for a while.

    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

    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.
