Curious if anyone know what exactly sport mode does.  I can certainly feel a difference.

 

Does it only change the transmission programming/shift points?  Or is there anything else related to the engine programming or perhaps DFM?

 

Still new to this truck, but it feels like there is more of a difference than transmission shift point changes alone would give.

Yea it lowers gearing, has quicker shift points and the engine RPM's are also increased.  It downshifts quicker too so RPM's are kept at peak.

Yeah- it makes the steering a little heavier. I think the DFM changes a bit too- just from what I’ve noticed.  It still drops cylinders but not quite as readily.

Yeah, it does, bit heavier and maybe not as quick (maybe).  Tried it out on the trip to NV this week, and it really helps me on the curves; gives me that old "feel the road" sense you used to get from vehicles that didn't steer by wire.

I wish there was a way to keep a mode set... while they are at it make tow/haul turn on when a trailer is connected instead of only showing a stupid alert to turn it on. 

 

Probably some gas mileage / EPA thing...

It makes wives bitchy. It's more responsive to small throttle inputs, which mine notices and then uses as an excuse to chew me out.  I've learned to save sport mode for.my own time.  

 

I think everyone already covered what it does.  Once we crack the ECM, I'm hoping HPTuners and Trifecta can have the sport mode be the ARM state for the tune, so I don't have to turn cruise on and off.  That gets old.

Leave wife at home, open door, put on seat belt, push start button to fire up the 5.3/8 spd., push start/stop button, rotate control to sport and ready to rock and roll on back roads w/hairpin turns on 285 R22 50's.

I have been running it quite a bit after I saw this post.  It seems to get better fuel mileage and is more responsive.

anyone done any unscientific study on mpg in sport mode?

Pretty much anything that encourages your to mash down on the gas pedal a little more is going to consume more gas.

 

Like the guys who tell me an exhaust and intake will improve my gas mileage -- no it won't, because I want to hear it!

? That's the truth! Since I modded my exhaust, my MPG has definitely gone down. It's too fun to run up to 50mph from a stop light and hear the V8 growl!

    • I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.       
    • Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.  
    • I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires. 
    • Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉       
    • I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
