    Innitial base(safe) tune and winter fuel is my guess as well. Things should improve as you continue to log and update revisions. 8-10mpg is highway towing mileage for my SC truck on stocksize(33") KO2's
    I'm only 35 miles south of you, or 45 miles East depending which home I am at. Center Point and/or Lake Delhi

    I got my final update for the engine portion of the tune this morning. Sure is nice knowing it's dialed in perfectly.

    -Greatly reduces Transmission temperatures

    What kind of drop in transmission temps are there when using tow mode gear locking?

    would it be of any help developing the Tunes for the 2019s If i sent you my 2019 ECU while I'm not using it?

    Not totaly scientific as ambient temps do play a part. That said towing the same load 8-9K # across the same route at 65mph I saw an 8-12 degree drop average. I had seen a high of 212 previously, and never exceeded 204 with the gear lock tune. Usually running around 195-200.

    Good to hear. I too got my last minor revision. Its been like a 6-7 month process but so worth it in the end to have the truck perfectly dialed in. :)

    That's a sizeable decrease. What gear were you in? Reason I'm interested is that I've a 19 w/o the cooler and tow a 6500lb 5th wheel. :(

    5th mostly but at times I can pull 6th across light rolling terrain. Bear in mind I am supercharged and your results may not be the same.

    Finally got my tune for the Sequoia today! :broccoli:

    Was sent stock file (base tune?) and 91 tune. i'll be running 91 tune minimum obviously with the S/C, and will likely request 93 tune (or map switch between 91 and 93 with tow haul if that's possible)

    i had to buy a new charger and battery voltage was at 12.7 volts at time of flash so no problems at all. my old charger barely held it at 12.1

    had a minor heart attack when i started the truck the first time, it stalled. but fired right up the 2nd time. gonna drive it like this for the weekend then do some logging for fine tuning.

    i'll report any observations and driving impressions :burnrubber:

    @OVTune TY Mat!

    When you flash these, they start and die the first time. Totally normal.

    @OVTune ..... Is it necessary that I log while towing my 4500# boat, or just do the logs without, and you do your magic from there? I've not sent in my first logs for the base tune yet, since I just got my truck back. Can't do any logging till Tuesday.


    edit..... hadn't even sent you the ECU ID when this was written. :rolleyes: Just sent that today.

    So does this tune when using gear lock mode effectively turn my truck into a manual transmission of sorts? Also when not using gear lock is it making the transmission shift smarter so to speak? :confused:

    Gear lock = You will have to shift the truck up or down(minus the clutch of course) As to your next question it should overall from what I have gathered from other peoples opinions on the tune in general. For me the tune firmed up shifts in both the primary and even more so with the towing tune I requested.

    Today is 8 weeks since I sent my ECU data. At 4 weeks I was told soon. at 6 weeks I sent an email asking if 6+ weeks was normal as if so I'm not interested in participating. The response was no, 4 weeks is not normal.

    At this point 4weeks would be "ok"

    My messages have been answered at best within more than 4 days. (at worst ignored)

    I sent an email yesterday saying today is 2 months, no response yet (hasn't been several days)

    I need my base tune for order 5325 by Monday morning or I will be filing a dispute with my credit card, If I am forced to do that I need an address to return the hardware.

    I have held off making this post as I don't want to call Mathew out but this is unacceptable. Nowhere does it say there is a month+ wait for tunes.

    How is your towing tune set up? That's something I'd be looking for as well.

    Its based off of my primary tune but according to Matt he tweaks it so it is a bit safer under load and at elevation. Much like stock in tow haul mode it runs the gears out longer to keep the motor in its powerband while under load and shifts are former and crisper. My set up is currently Tune #1 primary at start up. Tune #2(towing tune) once tow/haul is pressed. Gear lock is active in both once shifted into S-Mode.

    So if gear lock in S mode is now active with both tunes how are you towing? I mean are you leaving it in D and simply letting the tune run the transmission? Does the towing tune restrict the tranny from shifting into 5 or 6? Sorry for all the questions but it's all new to me. Thanks.

    Most of the time while towing I just put the truck in D Tow/Haul mode and drive. There are times when I want total control and shift into S mode/Gearlock like long distance on the highway to keep it from shifting down in the rolling hills, and at the boat ramp to keep it in power and not upshift halfway up the ramp, Etc... Feel free to PM me with any other questions :)

    No. Not manual. If you have Gear Lock + Direct Shift, then that's the closest to manual. Direct Shift will let you manually upshift the transmission without the computer interfering. It is instantaneous. Gear Lock holds the gear until you downshift manually or if the rpm falls below 1500, then the transmission will automatically downshift. If you have Gear Lock feature, go on a highway, put the transmission on S mode, shift up to 6th gear. Now press the accelerator hard, it should not downshift above 1500 rpm. Now this allows you to use all the available torque for that rpm. if the rpm drops low, then it is time to downshift manually to 5th.

    Just be careful not to forget that you have this feature specially if you are going to pass a slow vehicle on a two lane highway. The transmission will not downshift even if you floor it unless the rpm is below 1500. if you don't feel comfy with this feature you can request to have this feature removed.

    Shouldn’t take that long unless it is a new ecu calibration that isn’t yet supported. @OVTune

    To me, being used to manual transmissions my entire life, this gear lock direct shift sounds like the optimum towing setup. :thumbsup:

    Mat, when you posted this I couldn't help but feel like something was missing...

    The flex fuel tuning

    Are you still planning on this?

    It is and can be under certain circumstances as long as you remember to row through the gears up and down. Like Art64 said just dont forget to downshift if passing someone or pulling a load up a hill. I find it especially useful for holding upper gears on long highway trips and the tight twisty and hilly back road over to the boat ramp myself. I too have driven a manual most of my life and still have them in my Cobra and Shelby and without the clutch and actual shift pattern it can be just awkward enough that I have had a brain fart mid hill while towing waiting for the truck to downshift and suddenly realizing/remembering I had to do it myself.

    @OVTune

    Fellow modified 18's this is a direct quote from the "Dealer Letter"

    "NOTE: If a vehicle has non-Toyota-approved modifications that have changed the ride height of the vehicle or the factory installed position of the millimeter wave radar sensor, the owner will be required to sign the “Non-Toyota-Approved Modification - Owner Acknowledgment Form” before the remedy is performed. The remedy for modified vehicles includes the following additional steps:

    • PCS will be set to “OFF”.
    • PCS will be configured to retain the last setting following a key cycle.
    • A notification label instructing the driver to use Constant Speed Control and not to use Dynamic Radar Cruise Control (DRCC) will be applied to the dashboard.
    • An owner’s manual insert will be placed in the owner’s manual.

    Not all vehicles with non-Toyota-approved modifications will have the remedy performed.

    Examples of non Toyota-approved modifications the remedy WILL be performed:

    • Modifications that affect ride height, such as lift kits, and/or oversized wheels/tires.
    • Toyota original equipment grilles installed on trucks that were not originally intended for the trim level of the vehicle.

    Examples of non-Toyota approved modifications on which the remedy can NOT be performed:

    • Aftermarket grilles
    • Grille guards
    • Winches
    • Light bars
    • Aftermarket steel bumpers

    In these cases, if the owner restores the vehicle to its original design at his/her expense, the remedy will be performed."

    I guess I got lucky. I have an 18 with a 3" lift, the dealership, without question, recalibrated and updated the software for the PCS system after my bodyshop replaced my hood & grill surround when a big tree branch fell on it.

    Thanks for posting this, it definitely varies from dealership to dealership.

    I'm going in armed with this letter. We literally have only 1 Toyota dealership in Hawaii....... I'm up 6 inches and hope this works because I'll be screwed on my tune......

    Haven't found (honestly haven't looked in all 2440 posts) an answer to this....... with the tune and gear lock, etc, does the tranny still shift to 4th gear when moving along in 6th gear in D? I always hated that feature, driving along at 65-70 and having it go to 4th gear when you move the lever to "S".
