New 2015 Expedition 4x4 Owner Flat Towing

[JExpedition07]

That’s a BIIIG motorhome. Looks very nice. I thought it was turbo lag on the diesel because it does catch flies when it does. Can’t really find much on eliminating it from reading other than chips and such. I bet if I raced it and the expy side by side to 60 the expy wins simply due to off the line lag.

Nice coach! I saw your posts about flat towing it and wondered why you are using a trailer if you can flat tow? I guess it saves your tires. Btw, whenever I refer to my coach as a bus it's not a misnomer lol. It was actually a 50 seat charter bus with a stainless steel restroom in the rear at one time:

Daaaang... y'all downright nomadic or what??

That will work on your 6.7...and will take A LOT of that lag out without increasing power.

What will this do for the Expedition, or maybe the question is how does it work to remove the turbo lag?

I really dislike that they use the term “Turbo Lag” in there website write up. Most of the from stop lag/delay, is because of an intentional programming by Ford. All modern Fords have electronic throttles, as in your right foot pushes a pedal which tells a computer to do stuff. There is delay there intentionally to help maintain traction and give a smooth takeoff. Some vehicles have a sport setting that decreases that. Ours do not.

Pedal Max, and other devices like that remove/decrease that electronic delay. JMS actually gives you an adjustment knob so you can vary/tune how aggressive the throttle is.

Basically it demands action from the computer quicker, so you are in boost faster, but without increasing boost and power. Just takes the delay out.

That's pretty cool. How would that work with that tuner that you posted in a different thread. Would they work together or against each other?

LMS and Hypertech already decrease/remove that delay. The Hypertech gives you some adjustment, with 5 options on how aggressive the throttle is, Stock, Street, Performance, and Tow. My Aggressive tune from LMS, for my Edge is like it’s stock Sport setting from the factory, Sport with Aggressive loaded is like a hyperactive teenager. I expect LMS could do the same on the Expedition.

The advantage to the Pedalmax is a more responsive throttle, less “Lag”, but without more peak power. Pedalmax is designed to work also with JMS’s other product BoostMax which NASCAR Mike is going to try. BoostMax fools the computer in to demanding more boost, and Pedal Max takes out the electronic throttle delay. They compliment each other.

As I read J's posts about the delay...I was wondering if his TB could be recalibrated as we can do on my little two seater car. When I notice it "go soft", I just calibrate it and it leaps off the line again...guess Ford is using a resistor setup?

BTW guys....Gas mileage up to average-since-new= 17.9 with over 25K as of a week or so ago!!

It is all electronic, and computer controlled. The Pedal Max just modifies the signal going from the TPS(Throttle Position Sensor) to the ECM.

Touring musician? Do we KNOW you!

 

[Muddy Bean]

Likely not. Gospel music. I'm a nobody honestly. But I love what I do and get paid well to do it so it's a win win. Flat towing the EL for the first time this coming Sunday headed from Texas to California...

 

[Muddy Bean]

Flat towed the EL for 1,000 miles now. No problems whatsoever. So easy to put transfer case into flat tow mode. Really really happy with my setup. Awesome engineering on this front Ford:

When you flat tow I am assuming the mileage does not show up on the Expy?

 

[Adieu]

Gospel music, eh? Never quite understood what the point of that was.... oh well, if it pays the bills why not

 

[Muddy Bean]

No, ignition is turned off so miles do not rack up thankfully. Did notice tonight when I unhooked that the steering was pulling hard to the left. But after driving around for a while it fixed itself. Almost felt like the steering needed to recalibrate. Weird.

These trucks have electronic steering not hydraulic so if you turn the wheel from stop to stop it will recalibrate the center point.

 

[Muddy Bean]

Ok that's what I'll do from now on. I knew they were electronic just didn't know the recalibration sequence so I did exactly what you just mentioned: rack to rack and it did seem to fix it.

If you ever notice when you are driving with a cross wind and you have to hold the wheel into the wind after a while you have to hold it with less pressure because the system realizes what you are doing and takes away a lot of the effort you having to turn the wheel into the wind.

That would be nice to have. The hydrolic isn’t that smart.
