sports mode is it tb or tranny?
 

when using sport mode what is it that makes the truck responsive?

is sport mode changing the throttle body settings? or the actual shift points?

either way sport mode is great except for the crazy down shift slowing down hill.

I believe it changes both. Definitely the shift points.

true. but what is actually changing withe the button press? sport mode doesn’t add hp so something in the cpu program is changing mapping? or is sport mode actually changing timing and air flow?

I've heard it doesn't really add any hp/tq or cut any time off of 0-60 and 1/4 runs, so I doubt anything is changed with the timing.

I think the cpu just enhances the throttle response and ups the shifts.

Someone here with more knowledge of this than I should chime in as I'm interested to know too.

It can adjust the timing and air flow with the CPU.

On our former Honda's with the 3.5L V-TECH V-6 it would adjust according to how much throttle you gave it! :thumbsup:

Sport mode (and tow/haul mode for that matter) changes two things:

1) Less gas pedal travel to get the same result. "Sport mode reduces the frequency of having to step on the gas pedal to reach peak torque – resulting in quicker acceleration with less pedal travel. The truck feels more responsive to the driver’s pedal inputs."

2) Holds gears longer. "That means less shifting on engaging drives, such as twisty roads with rolling hills. Instead of shifting gears up and down for peak efficiency, the transmission holds a specific gear longer to make driving more responsive and spirited."

good answer- thanks -

anybody know how sports mode makes that crazy down hill down shift but the pedal commander doesn’t?

No the only thing it changes is pedal angle so you don’t have to push the pedal as far down to get up in the higher up/tq range and shift points. This was confirmed by the chief of engineering for ford in a video I watched.
