    How is the tech supposed to check for the update? Just click "Health check" or is there some other way? I'm going back in today and want to be armed with some info from those who have done it. He said nothing came up when he clicked "health check". Thanks.

    They perform the Health check. It asks them which computers to check. They tick the power train option. If the Calibration IDs are outdated there is a clickable link that says UPDATE. This link opens a page that shows every TSB that can be used to upgrade the calibration ID. The tech will read all of these. Once he finds one that applies to your truck and condition used to justify the update they click on the appropriate calibration ID linked in the TSB PDF. Then they run the Calibration Update Wizard from the file they just downloaded.

    So from the dealers perspective it's not just as simple as clicking the update button.

    I drove on TSB about 1K and have to say that drivability is worsening. 1 to 2 and 2 to 3 shifting is no longer smooth, especially during city driving. Truck sounds different too.

    It seems that the pedal sensitivity is reverted back. MPG is about the same, however last night I drove wide open road that I usually take daily and that trip mpg was the same when I drive during pick hours

    I guess I'll wait a bit longer to see if things improve, otherwise OV 1.05.

    I'm not aware of one. In fact my not cheap Snap-on will change settings on my friend's VW but not on my truck. J2534 pass through is the way to go. That's going to be my Christmas present to myself.

    So for you guys that use S5 how does driving in that mode and adding ECT interact? I tried it and it seemed with ECT on to add somewhat just like ECT on in D but not sure

    They are exactly the same. ECT doesn't work any differently between D and S mode.

    You are correct, but limited to 5th. Not sure I ever saw 5th in ECT using D but never used it on the highway. Will try that soon.

    You may find you don't need ect when in s mode. I don't care for the long shifts in ect so I never use it.

    ECT also changes the throttle feel. It's not just different shift parameters.

    That what I assumed would happen, but I see too much fluctuation for it to be cumulative. I will say most of the time it's real close to 22mpg, but it only takes one trip to the mountains to cause a big jump and then another average tank commuting for it to go back to more or less normal.

    Maybe your tank to tank is more stable so the overall is also more stable.

    Posted this in another thread but thought i share my experience here.

    Short story: 100% Much better driving experience.
    No abnormal surge, Smooth shifting in town and on highway, holds gear longer and therefore easily maintains speed uphill.

    Long story:
    So yesterday i got the ECU reflashed to their latest TSB 0062-18. They drove 10 miles per mileage pics i took before/after.
    Driving in town from the dealership to home, it was noticeably smoother and kinda the truck felt light because the trottle response and acceleration was smooth, not jerky or surge acceleration.

    This morning going on highway, it felt smooth and lean. Going up hill where the truck usually struggles to maintain speed on same pressure on the gas pedal. It now holds gear and moves smooth. I didn’t need to apply more pressure on the gas pedal to maintain speed which results in surge of accelration then drops then i have had to repeat. It used to struggle keeping 60-65mph with light pedal pressure going on uphill, not anymore.

    I dont understand how others experience their truck reverting back to the sh*tty acceleration. Hope mine doesn’t. Pretty sure ECU reflash are permanent update unless new ones applied over it.

    Will keep updating you guys but for now I’m very satisfied. The truck drives like it should!!!!

    Also, changed the turn signal blinker from 3-6 blinks. Charged me $57.50.
    They couldnt disable door chime, said its part of safety module? Which is part of seatbelt etc..etc..

    Update:
    Today drove some more in town and on highway. And I now have another word for TSB-0062-18, i call it “Refined ECT mode”.

    Got it done today. Seems a little smoother so what? More important it down shifts sooner when dipping into the throttle whether level or going up hill. Used to hold lower gear even after cresting hill and starting down. No more. Now shifts up as soon as a hill is topped. Its a difference and I like the improvement.
