Our best-in-class Power Vision 4 bluetooth flash device is now compatible with this new type of ECU, and will start shipping June 2025.

Of course, we understand this exciting news comes with a slew of questions, all of which will be revealed with time, but for now, we've compiled some FAQs for you below, along with some helpful resources to help shops and riders get ready for this launch.


How can I tell my vehicle is a Generation 2 Milwaukee 8?

If you're curious or unsure if your bike has this specific ECU installed, take a look at your bike's cam cover and or handlebar controls. If the cam cover is shaped like a rectangular kickout or your handlebar controls are of the new style that almost look like a video game controller, then yes, your bike is a Gen 2 Milwaukee 8 and this PV4 will work with it.

If I already own a Power Vision 4, can I use it on one of these new bikes, like a 2025 Road Glide?

Yes, in June, we will have a firmware update to support these fitments. Once installed, you will need to upgrade your Power Vision's Firmware. Then, in addition to the firmware, you'll need a new Feature License to make it capable of flashing the new Gen 2 applications.

How does licensing work for tuning multiple bikes with a single Power Vision 3 or 4 device?

Each vehicle requires a Flash License. The Power Vision 4 is privy to our Flash License program, allowing the same device to be used on many bikes (new or old) through the exchange of Universal Tokens. As always, each new PV4 comes with the ability to Flash ONE vehicle, so you only need a new license if you are flashing more than one vehicle with the same device.

With the Power Vision 4, you can open the stock file in Power Core to begin making custom tuning parameters for tables, spark events, etc. Data logged on the PV4 can be opened in Dynojet Power Core (WinPEP8 data center) to analyze bike performance or isolate issue. With Power Vision 4, tuning shops can stream data live into Power Core by connecting the PV4 to a dynamometer or dynoware main box via a CAN cable. Wideband data logged via PV4 is also reviewable in Power Core.
