    2018 Triumph T-120 Black

    Firstly, I have the correct OBD dongle with the latest firmware. Correct version of TuneECU with a compatible Android device, TuneECU is licensed and registered, bike was on a tender and headlamp fuse removed.

    I attempted to upload the tune and it got to about 99% before it failed. After a couple hours of trial and error, I was finally able to upload the stock tune back to the bike. I wish I could type out everything I did during that process but reprogramming the bike was not obvious and TuneECU's support page is poorly formatted. (I'm guessing somewhere in here I may ruined my chance at uploading the DNK map) I had a running bike again and scared myself away for the night and decided to try again in the morning.

    Bike starts fine, everything connects and reads fine on the tablet and TuneECU, but after opening the DNK tune, hit reprogram, and upload the map, it's not actually uploading the DNK tune. It cycles through the digital process, and I hear the bike responding to the new information but when it says its complete and I'm instructed to turn the bike off for 5 seconds then back on, TuneECU clearly reads that the bike has the factory map uploaded, not the DNK. I tried the process multiple times and even went on a ride hoping there was an off chance the bike just needed some time to process the tune.

    I've emailed for support and hope to hear back on Monday, but I'm very frustrated as this tune was my personal "icing on the cake" and now I'm sitting on $600 worth of electronics and a digital map that I can't use. (technically I can still use the tablet, but I only bought it to complete this tune and intend on returning it after)

    Are the map numbers the same as well as the map version?
    FYI the DNK map is written over the stock Triumph map. If the version numbers are different at least you’ll be able to confirm which one you’ve uploaded even if you can’t read it.

    First two pics are the DNK download file, and the map info
    Second two are what shows when I select “ECU>Information”

    The last photo shows the ‘This Map is protected’ watermark. You may well have been successful!

    The VIN info and the exhaust information shown will in all likelihood be historical left over data from the OEM map as the DNK map fuel & ignition tables are overwritten on top of the stock Triumph map.

    Yes, but that shows any time you simply try to view the map since DNK doesn’t want them to be duplicated.
    I can pull up any other map and view it’s data without uploading it, so long as it’s not protected.
    With the screen that shows my ECU info with my VIN, it shows the stock map and the correlating map info, which is where I would *expect* to see the DNK map, but I could be mistaken. I guess the better question would be, is there a way to verify in TuneECU or elsewhere, that my bike has the new map?

    Agh, I mistakenly thought you were viewing that info via the ECU, not reading the file through TuneEcu app.
    DNK used to advertise the fact that her map was undetectable to the software used by Triumph dealers, so the only definitive way I can think of would be to modify the info page on the DNK map, even something subtle like adding a period/full stop after the final word ‘fuel’ to differentiate it from the OEM map so you’d then know if you had the new map or not when interrogating the ECU. Hopefully the map info section is not protected, otherwise the only other option - weather permitting - is a test ride.

    Unfortunately you would need to upload the map again after modifying the info information.

    I could reprogram stock tune, ride, then reprogram new tune, and ride again to see if there's a noticeable difference...

    I emailed DNK customer support on Friday, so hopefully I hear back Monday

    I uploaded stock tune, went for a ride. Loaded DNK, went for a ride, didn't really notice a difference.
    ECU settings does reflect that there has been more total downloads, but I have the same issue as before. ECU settings shows no difference in map or it's info.

    However, I forgot to do the "12 minute tune" after.
    Do you think it's really necessary? The bike should adapt over time, right?

    As soon as you return home after a good ride, connect TuneEcu and run a hot reset. It’s just one ‘click’ on the App!

    DNK said I did everything correctly but did not address my question about verifying it was done within TuneECU.
    The bike feels better in 1st and 2nd, no more dead spot or snatchy throttle and pulls harder in the higher revs and gears.
    Ultimately, it did the job and the job costs $300. $600 if you need to buy the electronics. Was it worth it? Depends how much those "issues" bother someone. I was expecting a more drastic change, but that's probably a lesson learned in managing expectations.
    The bike was never designed to be a rocket and it's quirks are solved by riding more and learning the bike.
    The better question is, if those issues ARE worth solving, could it be done without a remap or for less money? To that I say, no. The install was easy and it did what it said it would do.
    For the money, the most meaningful upgrades have been upgrading the shocks, luggage rack, and adjustable forks, in that order. And the shocks were hardly more than the tune (ebay ftw!)

    From DNK:

    1. "Reprogramming Complete" message after flashing
    2. Your motorcycle starts and runs afterward
    3. Your ECU flash counter in ECU - Informations will increase incrementally by one.

    ECU - Information will always show your stock map code, because it's literally the only map code your bike can take other than ones from the same exact model but in other regions of the world.”
