• Throttle current-ceiling speed roll-off disabled in mode 3
• Faster throttle rise rate in mode 3, low and high speed alike

Compatibility

Built from the stock controller 310 image, and applies to any bike whose motor controller reports a 3XX version.

Changelog

v1.0.0

• Initial packaging of the factory image

What this is

The factory 310 image exactly as shipped, packaged so the same tools can flash it. Nothing about it is modified.

When to use it

Flash this to undo a custom release and return the controller to factory behaviour. It appears in the guide’s firmware list alongside custom releases.

Controller firmware cannot be read off the bike, so this is the factory image rather than a backup of your own bike. It restores you to stock only if your bike started on a version it replaces.

About

This is the first custom firmware for the Diamond Display. It’s based on NRF version 221122, which is the “torque update”. It’s patched to default startup in mode 4 (off road mode), instead of mode 2 (US Only, for now). Additionally, this firmware has been patched with a new public key (SuperDuper Skeleton Key) to allow for future patch updates to be applied via Bluetooth.

Finally, the word “versions” on the display’s settings menu that shows the version numbers has been patched to show “versionz” in order to visually verify the patches have been applied.

Compatibility

This firmware should work on any display that is already running NRF version 221122. However, it may work on earlier versions as well. If you try it out, let us know how it goes in the Discord server!

Warning

Applying this firmware will likely void any warranty. Also, this firmware will not accept future official updates from Super73.
