Guidance needed: Derestricting 2020 Rocket 3 GT using TuneECU & OBDLink MX+

[Willyk]

Hi everyone,
I am planning to remove the factory restrictions (speed and gear limitations) on my 2020 Triumph Rocket 3 GT.
I already have the necessary hardware and software ready to go:

• OBDLink MX+ Bluetooth adapter
• Registered TuneECU app (Android)

Since I have the tools required for flashing the ECU, I would greatly appreciate some step-by-step guidance or tips from anyone who has done this exact procedure on a 2500cc model.

• Which map/tune do you recommend? Should I look for a specific custom map (like the Penner tune) or modify the stock map's tables myself?
• What are the most critical steps to avoid bricking the ECU during the Bluetooth flash? (e.g., pulling fuses, using a battery tender?)
• Are there any hidden tricks I’ve read that you might need to disconnect from the bike in the app before you can actually modify the tables—is this true?

If someone could point me to a reliable guide, a specific thread, or just share their own experience with this setup, it would be a huge help!
Thanks in advance,

---

Since you're looking to add the ponies left at the factory with TuneECU I'd recommend you use Ulf Penner's tune in the custom map database. You can use TuneECU to find what map you currently have loaded using the "INFORMATION" tab in the software when connected to your Rocket. The three dots in the upper right corner on most versions of the software. There are also lots and lots of tutorials on Youtube for using TuneECU. The map number you want to load has been tweaked by Ulf. The map number is 31013 or 31012 on this table (for example only, your bike may not be in this range), they are NOT interchangeable as stated. Putting in the wrong map will not damage your bike because it won't start or even turn over when you hit the starter button. Putting in the wrong map is easy to identify because nothing works afterwards. Reloading the correct map is easy to identify because it starts right up. The OEM stock maps are also in the database so you can always go back to the original starting point if you need to. I recommend you use the map number and not the VIN as that can be confusing if you're close to the edge of model years. One more thing, if you have cruise control (you should) you'll lose it after installation of Ulf's map until you run the cruise control switch check. After you run that procedure (takes 2 minutes max) your cruise is restored.

Plug your OBD into the bike and set your rocker switch to the ignition on position (make sure you have your fob as the power needs to be on). After fuel prime, connect to the OBD with TuneECU. When the connection is made the light bar at the bottom should turn green. Watch this video and you'll get a lot of questions answered:
