Thats why im asking here, I dont want to destroy anything. I do not own a computer, but my phone is android.
I hate how lean bikes come from the factory, thats why I want the tune. I installed exhaust which doesnt help the lean condition. I dont need the extra power. I simply want it to run better. Im fully aware that im computer stupid, all I asked was how to do it to try and understand it.
I do have friends that can help if I have the run down on what to do.
I have always just bought power commanders or fuel pacs and pluged in the supplied map, never had to install a map this way.
As a few folk have said, it's not *too* difficult to do, if you just follow the steps. And if your phone is android, you have 1/3 of what you need, just buy TuneECU and an OBDLink LX or MX+ bluetooth OBD2 adapter and you're away. The difference between the two devices is mainly an extra cost for the MX+ for more manufacturer-specific capabilities (mostly cars). I bought an MX+ but I did get a decent discount at the time. The product page for the OBDLink products is
OBDLink and you can also get them via Amazon. Note that other adapters work, and you'll find no end of opinions on TuneECU forums etc of people complaining about either the price of the OBDLink units or how their no frills Alibaba BT OBD2 doesn't work properly, and the support team just tell them that the supported adapters are the OBDLink ones. Save yourself a potential headache and just get one of the supported ones. You bought a Rocket 3, a $150 piece of hardware and a $25 piece of software are way less than the one carbon fender you are thinking of getting!
The link to the actual custom tunes on TuneECU is at
Custom Tunes where the new Rockets are at the bottom of the page. They are separate for GT, R and TFC, and have a US/Canada and Rest-Of-World tune for each.
With Android you can download the zip file directly to your device and use the native "Files" app to unzip it to extract the .hex file you load into TuneECU. Some folk complain that TuneECU can't see the tune, but that's normally either they forgot to unzip it, or they didn't store it in a folder that TuneECU can see by default without having to browse for it.
Note that some folk complain about registration issues, but it is not instant (takes a day or so) and when you register it is important that you record both the email account the device uses and the one you use for PayPal. Whether they are the same or different, you should put them in both fields in the registration box. That way the author can tie to license to the device even if the PayPal email is different.
You need to pair your Android device to the OBDLink device, and it needs to be plugged into your bike (or a car) to get power to do that, and you use the OBDLink app to pair before you use TuneECU. Once all that is done, follow the instructions for loading the map and applying it. I walked through those application steps in detail on my YouTube page, and highlight a step you SHOULD NOT do, which is resetting the adaptions. The latest Triumph ECU's are adaptive, so you just load the tune and ride. See the video here:
