Frequently Asked Questions

What should I expect from a tune?

The tunes provided by DNK TuneWorks are the result of hours of testing and development in conjunction with customers and Triumph and Ducati enthusiasts and technicians to ensure the best and safest tune for modern Triumph and Ducati air- and water-cooled engines from 2000 onward.

What do I need to get started?

Given recent changes with the TuneECU installation and configuration, for novice or beginner customers and users, we recommend selecting the “mail-in” option for their ECUs. It will save you time, frustration, and money to allow our professional staff to provide this service and test that the tunes have been loaded and are working.

For advanced or DIY users, we recommend that you purchase an OBDLink Bluetooth LX, MX or MX+ device and TuneECU software via the Google Play Store or TuneECU.FR using an Android device. With these tools unit you can upload a custom calibration developed by DNK TuneWorks to your motorcycle. 

For motorcycles which require the use of a cabled connection (pre-2016) please find an appropriate TuneECU-compatible adapter here.

How soon will I receive my tune?

We aim to turn around the development and delivery of your tune within three (3) business days of the initial order. This excludes weekends and holidays. This is not a guarantee, this is aspirational based on our workload and number of orders at any given time.

Will updates also be free?

If there is a major change to the tune, mapping, or associated data with your tune that requires immediate attention, and updated file will be sent to you. For a period of fourteen (14) days after the initial sale, any additional changes, modifications or updates to refine the tune will be available to the primary customer.

We will not make exceptions due to “life got in the way” or delays for providing feedback or data from customers to refine the tune outside this fourteen (14) day window.

Are there discounts or promotions available?

From time to time there may be promotions and discounts available.

I need a specialty tune. Can you create one?

Each and every tune is specially created for the customer and vehicle.  Various modification combos are continuously tested and thus it is vitally important that your full mod list be known, so your tune can be tailored for you.

Is there any documentation and support for the tunes?

There is support available from DNK TuneWorks for a period of fourteen (14) days after the initial purchase and a thirty (30) day order documentation before archival, any support and documentation past this period of time is up to the sole discretion of DNK TuneWorks.

What is the refund policy?

We do not accept refunds after delivery of the product to the customer. It is up to our discretion based on the circumstances surrounding the request if a refund or other renumeraiton will be issued.

Do you charge sales tax?

We currently only charge sales to orders being shipped to Washington. Any others shipping to other states are not charged sales tax.

What will a tune do, and won’t do?

Tunes will not “fix” a bike that comes to us that runs poorly due improper care, skipped or poor maintenance, mechanical failure and/or the selection of poor-quality after-market parts. If you choose to have DNK TuneWorks develop a custom tune for your motorcycle, please ensure your bike is in proper mechanical working order before purchasing.

A tune from DNK TuneWorks will address some performance limitations that are inherent in stock tuning from the factory, and are built to optimize fueling, power as well as the combination or addition of mid-market or higher quality aftermarket performance parts for your motorcycle. Such improvements include headers, exhaust, air filters, wheel sizes, tire types and gear ratios.

A tune will not affect riding modes (add or takeaway). This includes NOT affecting anything displayed or your gauge cluster (basic LCD or TFT). These are performance mods and aren’t changing any base-level capabilities built into these motorcycles.

What does the removal of the speed limiter via the tune do?

The speed limiter exists for both safety regulations, but also was developed as a conservative ceiling to the top end performance of the engine as they tuned it from the factory. The custom tuning from DNK TuneWorks changes the performance, usually gaining some horsepower as well as how the bike will accelerate, and unlocking the speed limiter will allow those who acquire a tune from us to fully utilize what benefits the tune provides.

What’s the difference between the options for the tunes offered on the website?

We recommend only those who are sufficiently technically adept and are comfortable both with accessing their OBD-II port on their motorcycle and using Android-compatible phones and tablets in order to load their digital tunes. For those local to our shop in the Seattle Metro Area, we offer a drive-in tuning experience, which will require a few hours to customize our tunes exactly to your specific bike and any modifications. This will result in road tests, and feedback from the customer on those tests and our technician if they remain on site for the session. Finally, for novice and/or “white glove” handling, customers can remove their ECU and mail it to DNK TuneWorks where we will load a bench tune onto the ECU and mail it back next day after receiving it via a method requested by the customer (domestic and international).

What support do you provide?

We do not provide support for your selected OBD-II dongle or attachment, we also do not provide debugging and license support issues regarding TuneECU, of which the former is handled by the device manufacturer you chose and the latter is addressed by contacting the TuneECU developers here and here with regard to functionality questions, bugs and other software issues.

We will provide rudimentary support for self-install customers, namely anything that may be directly related with the tune file sent to you, but all instructions required for a successful upload of the tune file to the ECU unit using approved hardware and software was sent along with the file and order for the customer to complete on their own.

Do you reserve the right to refuse to tune a customer’s motorcycle?

Yes. We have a policy, due to the desire to support our partners, vendors and maintain high quality control to refuse tuning motorcycles that do not appear in proper mechanical order prior to requesting a tune, or arrive as an order but are tied to a customer that has abused goodwill, or behaved poorly towards our partner organizations. This is to protect us, our partners, but also you, in order to ensure that your tune provides the best performance for your properly maintained motorcycle.

Can I do this if I only have an iOS (Apple) device?

No. The software runs only on Android devices. You can acquire a basic Android device with Bluetooth that can run TuneECU for under $50 in a lot of cases, sometimes cheaper. Please factor this into your planning if you choose to apply the digital file version of the tune. If you can not or choose not to use Android, you have the option of sending us your ECU to flash with a DNK TuneWorks tune and verify that it was applied.

Do these tunes violate laws or void warranties?

Some items used and/or installed by DNK TuneWorks may void portions of your vehicle’s factory warranty. Some items may not be legal for “on highway use”. DNK TuneWorks makes no guarantees to the legality of any parts used for “on highway vehicles” and accepts no responsibility for compliance with the vehicle’s factory warranty. Resale, trading, or distribution of a tune not paired with the original vehicle is not warrantied or supported by DNK TuneWorks.

Within the European Union, there is an environmental regulation, Euro5, which requires all engines and exhaust systems to conform to certain emission standards. Motorcycles sold within the EU, as well as internationally, are homologated to such standards to ensure compliance. Some countries allow modifications to the ECU software for use in racing and track performance and not for on-road use. 

In the United States, motorcycles and other vehicles are subject similarly to California Air Resources Board (aka ‘CA Emission Standards’) for emission standards, and are required to maintain certain parts and controls to remain in operating compliance. For customers who live and operate such vehicles in states with these controls, it is illegal for a customer to install or modify their vehicle in violation of these regulations. 

Common Issues

Not a noticeable improvement after loading a tune

Please ensure you have not accidentally re-loaded the stock tune back on to your ECU. This happens more often than you think. Make sure you open the tune and verify it within TuneECU before sending it via the OBD-II port and dongle. Make sure you are resetting adaptions and allowing the bike to adapt the new tune.  Make sure you are actually going full throttle. Make sure your tires can provide adequate traction. We actually have run into an issue where a customer’s TKC80’s were not providing adequate traction, and whenever they went full throttle, the bike would lose traction and engage the traction control.

TFT Dashboard not reflecting the increased redline

We are programming your ECU, and not your dashboard, so the digital display will still show your original redline.

Gear Selector / Engine Light

This is an uncommon, but not unseen, issue with the Speed Twin and Scrambler models from 2019 to 2021 when sending in your ECU. The motorcycle may lose track of what gear it is currently in when the ECU is disconnected.  This occurs randomly with no direct pattern to what combination of motorcycle, parts or other settings that creates this condition. Where this occurs, it may require you to visit a Triumph dealer to use their tool (which takes mere minutes) to clear this dash error. This is a non-destructive error, bound to the motorcycle’s software, and does not void your warranty if this occurs after sending in your ECU.

Low Fuel Light

After flashing the ECU on most 2016-2020 models, the gas gauge will reset. The bike only polls the bike for how much gasoline is in the tank when above 35mph and to third gear or beyond.  As soon as you ride your bike, the gauge will reset itself and show the correct amount of fuel in the tank.

Cruise Control Not Working

Occasionally, when flashing an ECU, the cruise control learn procedure may need to be done. The steps to this can be found with a simple google search. It’s a simple process to do.
