Description
Handheld tuner is for the GL1800s (with 38870-MJG/MCA GEN2 ECU)
4 years in the making and a first of its kind
THE ECU IS NOW UNLOCKED for the 2014+ VALKYRIE GL1800 engine.
After 4 years of testing and development, the stars finally aligned to allow us to release the first ever at-home ECU tuning device for your 2014+ Valkyrie GL1800! After huge response and amazing feedback, we decided to crack open the 2013-2017 Goldwing GL1800 for tuning as well. This has proven to be another home run and feather in the cap with the first at home tuning solution for these bikes ever offered.
Tune your Goldwing from the comfort of your own garage with our simple and easy to use handheld tuning device. This is a Goldwing first after years of mail-in ECU options. Our handheld tuning device allows for our modified ECU tune along with saving the stock tune in-case you ever want to go back to the original map.
With a low top speed limiter and a weird dulled throttle map, the ultra reliable Valkyrie benefits from a nice kick in performance along with improved throttle response per mode and of course, removing the pesky top speed limiter that has been a thorn in the side for years. With additional power over the curve as icing on the cake.
Dozens of Valkyrie owners have been begging us to address its unique engine and electronics for years and finally we have a solution ready and tested. Write verified and tested ECU remapping calibrations to your Valkyrie in 4 easy steps. Improvement in overall rider enjoyment is found without sacrificing fuel economy, emissions or reliability. Buy with confidence from the brand who has put at-home ECU Tuning on the map.

Dyno Testing
2019 Honda Goldwing (SAME ENGINE) GL1800 DCT (AE1) 91 octane tested at our West Coast facility on a Dynojet dyno before and after. 15+whp!
Below is a before and after BT Moto ECU flash +6-10whp gains and torque gains depending on rpm part of the power curve. Completed back to back same day on 87 octane on a mustang dyno.
Fresh from the ground up development on the 2025 EU5 (6 pin connector) Goldwing
This EU5 new ECU style Goldwing picked up almost 20WHP at redline! Big improvements over the EU4 4pin ECU counterparts. There is a lot of different logic in this ECU and took a lot of time to make work properly and safely while picking up great power. These EU5 bikes are substantially faster than the EU4 bikes in real world road tested conditions.
Goldwing EU4 (18-24) vs Goldwing EU5 (2025). As you can see the 2025 EU5 Bike (red) makes more power everywhere over the EU4 bike (blue). This is an apples to apples comparison. No mods on either, same fuel quality.
**All runs performed same day, back to back on an independent DynoJet**
**Testing performed with California ACN 91 octane pump gas. Usage of a lower octane will yield smaller power gains. Higher octane larger gains**
THE BT MOTO HANDHELD TUNER
BT MOTO HANDHELD PERFORMANCE TUNER AND WHAT ARE THE BENEFITS OF HAVING ONE?
Custom tuning at your fingertips on your schedule. Read and write your own motorcycle's ECU from the comfort of your home. No need to bring your bike to a shop, our easy-to-use handheld can be used in your spare time with quick turnaround. You now have a virtual custom personal tuner at your fingertips. Thoroughly tested by our own engineers, not just for its function but also for its durability, our easy-to-use handheld is just what you'll need to help get the most from your motorcycle!
CAN I JUST SEND IN MY ECU FOR FLASHING AND SPEND LESS? LET'S GO OVER THE ADVANTAGES.
- NO DOWNTIME - No need to send in your ECU or remove it from your bike at all. You order the handheld, it gets delivered to you nearly instantly, and you flash your bike on your time easily. You never miss a day of riding, and no effort in removing the ECU. If there are any issues, you can revert to the full stock state.
- READ AND CLEAR CHECK ENGINE LIGHTS - Full diagnostic of the ECU including the device.
- STORE MULTIPLE MAPS - When you send in your ECU, you only get one map. You might be thinking, "Why would I need more than one map?" Storing multiple maps means you're able to flash for different configurations. If you're a serious track competitor, we can work with you to get you different mapping for different tracks. If, for example, you're adding modifications to your stock bike, we can email you a file that takes the new exhaust into account with the changes you need to optimize your bike's new modifications with no mailing needed.
- GO BACK TO STOCK ANYTIME - Not only can you store multiple files, but you can also flash the original, stock file back into the bike at any time and for any reason for service, sales, and more.
- ABILITY TO TUNE FUTURE BIKES - Customers swap bikes all the time! With our handheld tuner, you are able to put the first bike back to stock, then reset the device and use the same device on your next bike, with a simple and low-cost transfer fee.
- ANY ISSUES? We can resolve nearly anything remotely, really quickly, with our engineering staff.
