    Ive been reading different threads. I saw mention about my Tundra's computer ( or something ) can learn my driving habits and it will adjust accordingly. Possibly give me better or worse MPG ? Can someone enlighten me to this? Just bought the truck yesterday and wondering if/how I get it to learn my driving.

    If mine had learned my driving habits, it probably wouldn't let me drive it anymore. :DI actually haven't heard of this before. It's a great question. My Bully Dog tuner will grade my driving habits and tell me all sorts of things about my engine performance, but as far as learning my habits, I'm not sure.

    Yes vehicles do learn your driving habits they adjust transmission shift points and fuel mapping. Not a huge thing you won't notice the difference most of the time. But just drive it it will learn in a few days

    YES it does, it is a learning ECU. IMHO the worse thing you can do to this engine is be a pussyfoot driver. I have owned 5 Tundras and a Sequoia with the 5.7 driven them all like I stoled them and still average better mileage than most the members on here complain about. This engine was designed to run, let it run.

    He’s right. I took it easy on my 2018 and it felt sluggish after a while. I’ve been flying around in my 2019 and after 3000 it feels like it takes off faster with better throttle response. Unless there’s something different from the platinum to the pro.

    I noticed when the truck was new that in certain situations the transmission would almost skip for a split second before figuring out what my right foot was telling it what to do. After about 2000 miles that all went away.

    You don't tend to notice it because it adjusts while time passes and you get used to it.

    To really notice it, drive like normal (in my case that means like an asshole.), then disconnect the negative battery terminal for a half hour or so. When you next drive it will have reset and you will notice the difference.

    Typically, I drive like an old guy (this is what i am). At least every other trip out though, I floor it at least once, so it’s not getting sluggish on me.

    everything black...except the wheels
    I also second this. I calc mpg by hand every tank, and have noticed a measurable uptick in efficiency as I have started to accelerate more aggressively. I'm talking about initially I would drive so the tranny would shift about 2,200-2,500 rpms. Now I let it get to about 3,500 and I've gained over 1 mpg on my last several tanks.

    If it feels sluggish press the tow haul button.

    Could be. As I mentioned, I drive like an asshole. I also average 15.5 city. My truck is 2wd but I also drive Monday through Friday 35 miles round trip at rush hour both ways in the city traffic.

    I do 18 miles one way to work. Half is highway the rest is through little towns with 35mph speed limits. Im hoping to get atleast 16 mpg as my Tacoma got me 18 and I promised the other half that it wouldnt cost much more in gas , lol.

    I pussyfooted my ‘15 F150 Lariat 4x4 from the 50k miles I bought it at til trading her in at 81k miles. I was so gentle on her thinking I’d keep, forever.. I was so let down when I traded due to the coolant leak at turbo line and failed cat converter that when I switched into my current ‘18 Tundra 4x4 with 10k miles, I now drive it like I stole it. At first I was gently accelerating and she felt slower and more sluggish than my Ford. Felt disappointed in performance, but happy about the reliability quality promise.

    Then I read here about the Tow Haul Ass button and loved it, though mpg dropped heinously. Now I keep it OFF tow/haul/ass and just drive aggressively in normal mode and get satisfactory MPG anyway relative to driving like a grandma. I find the v8 ECU once learned, makes this such a joy.

    I intend to buy the 10yr/125k mi VSA when I’m closer to the deadline. Just for insuring against a cam tower seal failure 9yrs from now

    You guys really have me wondering...I drive like a grampa, the transmission shifting between 1800 and 2000 RPM and I average 11 MPG +/- 1 in city driving.

    The 5.7 is powerful, though...letting her spin to 3500, she'd be roaring in traffic. Those old-school slow and easy driving habits are hard to break!

    Mine is the 5.7 4x4 and I’m just under 14k miles. Getting onto the highway on ramp I’ll rev up to around 4k rpm for the glorious v8 sound and it’s definitely the fastest vehicle I’ve owned and my first v8. I’m half highway, half suburb driving, and am at 14mpg combined. It’s amazing how effortlessly and quickly it will get up to 75mph.

    If I hadn’t been on this forum I would have mostly stayed under 3k rpm with my shift points accelerating; for fear of straining the engine (that’s how I’ve always driven all my previous vehicles.) But you’ve all inspired me to let the Toyota live a little..

    In the 30k mi I put on my previous F-150 3.5 Ecoboost it never saw past 2-3k rpm mostly and it still let me down..
