MK Fuel – Fuel Computer for EFI Motorcycles

MK Fuel turns your phone into an onboard computer for your motorcycle.

The module measures injector pulse duration and sends the data to the mobile app, allowing you to monitor fuel consumption, fuel remaining, estimated range and trip statistics.

It was designed mainly for EFI motorcycles that do not display fuel consumption or estimated range from the factory.

Key features

✅ Live fuel consumption in L/100 km and L/h
✅ Average fuel consumption
✅ Fuel used
✅ Estimated fuel remaining
✅ Estimated riding range
✅ GPS speed, distance and riding time
✅ Trip history and charts
✅ Separate Trip A and Trip B counters
✅ Automatic operation when the motorcycle is started
✅ Continues tracking fuel usage even when the phone is disconnected

Simple installation

MK Fuel requires only three connections:

• switched +12 V power,
• ground,
• injector control signal.

The injector signal is connected using a Posi-Tap connector, so the motorcycle’s factory wiring does not need to be cut.

The module only reads the injector control signal. It does not modify the ECU signal or interfere with fuel injection.

Calibration

After installation, ride normally and refill the tank completely. Enter the amount of fuel added into the app.

MK Fuel then adjusts the calculation to the specific motorcycle and injector setup. Calibration can be repeated after future refills to improve accuracy.

Compatibility

MK Fuel is designed for motorcycles equipped with electronic fuel injection.

It supports both:

• low-side injector control,
• high-side injector control.

The following parameters can be configured in the app:

• number of cylinders and injectors,
• injector flow rate,
• fuel tank capacity,
• injector control method.

Before ordering, please send the motorcycle model and year so compatibility can be confirmed.

Included in the kit

• MK Fuel module,
• connection cables,
• Posi-Tap injector signal connector,
• installation and configuration guide,
