W OBD2: Motorcycle Dashboard

pierre-laurent

About this app

Turn your phone into a proper dashboard for your motorcycle.

Plug a Bluetooth OBD2 adapter into your bike's diagnostic port and W OBD2 shows you what the engine is actually doing, live, on a screen you can read at a glance while riding.

WHAT IT SHOWS

• Engine speed and road speed
• Gear, including neutral
• Coolant temperature
• Throttle position and engine load
• Battery voltage
• Intake and outside air temperature, when your bike reports them
• Two trip counters, one for the tank and one for the journey
• Check engine warning, with the fault codes behind it

REAL GEAR ON SUPPORTED BIKES

On the KTM 690 Enduro R and SMC R, the gear can be read straight from the engine control unit, so it is right every time, including neutral while you are still rolling. This is confirmed on the Euro 5 bikes, 2021 and newer. On earlier 690s the control unit may not answer, and the app falls back to the calculated gear. The same engine platform is used by the Husqvarna 701 and GasGas SM 700, and reports from those riders are
welcome.

On every other bike the gear is calculated from engine speed against road speed, and the app learns your bike's ratios as you ride. That works well, but it cannot always tell neutral from first gear at idle.

FAULT CODES

Read the stored codes, see what the standard ones mean in plain language, and clear them if you want to. Manufacturer specific codes are shown as they are, never guessed at.

BUILT FOR RIDING

• Portrait or landscape, it reflows either way for however your phone is mounted
• Big readable figures, no decorative dials
• The screen stays awake while connected
• Reconnects to your adapter on its own when you start the app
• Five languages: English, French, German, Italian, Spanish

WHAT YOU NEED, AND WHAT IT WILL NOT DO

I would rather you know before you spend anything.

• You need a Bluetooth Low Energy OBD2 adapter. The very cheap blue clones use older Bluetooth and will not work. Three adapters are confirmed working and listed inside the app.
• Some bikes, including the KTM 690, need an adapter cable, because their diagnostic plug is not the car connector.
• There is no fuel gauge. Many bikes, the 690 among them, never send a fuel level to the ECU, so no app can read one. Trip 1 works as a tank counter instead.
• Your bike must support standard OBD2. On European machines that generally means 2017 onwards.
• Readings refresh about once a second. That is how fast the adapter and the ECU can answer.

PRIVACY

No account. No advertising. No analytics. No tracking. The app sends nothing anywhere. GPS is used only to work out your speed, and your position is never stored or transmitted.

Free, and part of the W family of apps from weathergpx.com.

What’s new

The engine warning light has moved to the top centre of the dashboard, next to the alerts, instead of sitting in a corner. It is the one thing on screen that no layout is allowed to hide, so it now has a place of its own. The settings page also lost the oversized scrollbar down its edge.
