    Yes I am aware we posted we are now setting up / working on supercharged tundra files.

    I'm guessing people aren't seeing these posts.

    If you have a 2018 truck, just wanted to let you know Toyota recently released yet another ECU update and new ECU version.
    I dont yet know if this is something all trucks need, but just so you know if you get this update we currently don't have any support for it. I am working on it right now.

    It was just recently released, so there was no way to have it planned ahead, or by july, etc. As far as I know it did not even exist at that time.

    Anyone know what is different about the 2019 and 2020 trucks that has delayed aftermarket tuning support for so long ?

    Some super complicated password protected stuff or what ???

    Not bagging on OVT at all... just an observation... and noticed it carries over to all the aftermarket tuners. (Bullydog/HPT/OVT)... and has probably prevented alot of supercharger installs as a result.

    Matt... have you dabbled with the '20 trucks yet ?
    Just curious how long I need to wait before being able to screw with my 2020. :monocle:

    The data is not possible to obtain off the ECU by any normal / standard way, unlike other ECUs.

    We have a way we do it, and it's why we are currently the only ones capable of providing support for 2019s. All 2019s are supported by us so they aren't really delayed anymore.
    I expect to have 2020s unlocked this weekend if I can get the time to finish benching it.

    I only check in here occasionally and this thread moves way too fast for me to stay up to speed. ;)
    I may need to dedicate a day or two to binge-read it in it's entirety. :thumbsup:

    Don't even waste your time. It' several pages of junk.

    **** It looks like these new ECU Calibrations are for trucks needing their fuel pumps replaced.

    There are even new ECU versions for older ECUs, which may make any previous patch work on those ECUs ...no longer effective.

    We will provide more information as soon as we can.

    If you have a Flex Fuel version truck and are affected by the fuel pump recall your ECU version is subject to change.
    currently we do not have support for any of these new ECUs, and will have support ready as soon as we can.

    Please don't blame me. Blame toyota.

    I have not been effected by the fuel pump so I assume I do not need the new programming from Toyota

    Just a thought, but FWIW, I don't think that an ECU ID is necessarily going to line up with a model year. Any model year could hypothetically have any number of IDs. There may be several for one model year and one for several model years being further complicated with different IDs for FFVs/5.7L/4.6L/4/0L in any given model year. Mat naturally would be more familiar with this... and subject to more headaches as a result...:annoyed:

    I find it incredibly frustrating that vehicle mfgs continue to make it more and more difficult for consumers to modify a vehicle that they PAID FOR.

    Cant wrap my head around this.

    I get the whole "warranty" and "emissions" thing... but for gods sake ITS MINE once it's purchased.
    The mfg shouldnt be legally able to restrict access to something you bought and paid for.

    It can probably be summed up in just a few words: Liability. Lawyers. Patents. Proprietary. I guess I could probably go on, but why...

    So far it only seems related to flex fuel trucks, 2016+.


    Toyota, like any manufacture, goes to different lengths to protect their firmware not from the consumer, but from other automotive manufacturers. Toyota, Ford, Chevy, etc doesn't want their patented tech to be copied. And it's likely they have to protect it so that it cannot be easily tampered with to defeat emissions.

    Toyota actually goes to greater lengths to keep you out than almost anyone.

    Disabling reading
    Disabling board reading
    Disabling NBD
    Disabling diagnostics
    Disabling access to the bootloader
    Using a special encryption when flashing over can that only the bootloader can decode
    Disabling read over can
    Disabling read by section over can
    And using unique password protection per individual ID.

    It's absolutely nuts. I dare say Toyota is #1 at keeping people out of their ECUs.
    They just had one fatal flaw on older cars that made it stupid easy when it was finally figured out.

    It's not really any different than me, or any other tuning company locking their tunes.
    1. You don't want unlicensed redistribution
    2. You don't want to have your work copied



    Bosch / tricore also go to crazy lengths, including unique keys, "tuner protection patches" master / slave keying. Etc.
    But there always seems to be a backdoor into them

    In the end it's always liability + protecting expensive work.

    Weird, because we just got 0CN62 file yesterday, brand new 2018 ECU

    it may be only for folks who are on the recall list.

    Matt, for my 2019 FF, I still do not have an available ECU update. Will I be able to tune my truck as of right now? You previously said there was an update for my truck and I'm not finding it nor Toyota list it.

    The only way then would be to send your ECU to us so we can unlock it, since I do not yet have 0CN60

    Is there an easy way to extract or find the ECU ID number ? or is that part of the OV Tune process ?
    (I do have an older ebay pirated copy of Techstream if that will work)

    Yes, I do believe that you can use Techstream. I'll need some time to try it with my copy before I can be sure and let you know how I manage it, unless there's someone else that knows off the top of their head. I'll do it this evening but wanna finish this movie. :)

    Ya, I don't think that you have to go very deep to find it, it's on one of the main screens isn't it?

    Do a health check and the ECU calibration ID will be on the very right in the results.

    So after goofing around and finding a different way to get the information, @ViktorG pulls it out of his hat!:thumbsup: ECU Update does it as well.
