FT550 2024+ Rotax 325 harness — 2002112825

The FT550 2024+ Rotax 325 Harness, designed by FuelTech, is the perfect solution for FuelTech FT550 ECU installation using the PWC OEM harness.

The wiring harness adapter has all connections to quickly and easily install the FT550 ECU, while retaining OEM gauge cluster, IBR (Intelligent Brake and Reverse system) properly working.

This wiring harness plugs directly to the OEM harness. There are also two spare extra connectors for inputs and output available in FT550 if you want to install additional sensors and actuators.

It does require the NanoPRO to read and condition the existing stock Bosch LSU 4.9 O2 sensor.

The stock 325 coils requires an external igniter that can be either a OEM 3 channel igniter we offer or an upgraded energy version that will increase spark energy, the FuelTech SparkPRO-3 Marine version.

The FT550 ECU, NanoPRO o2 conditioner and ignition module are not included, purchased separately.

NanoPRO — 3010009597

The 3-in-1 NanoPRO is a Wideband O2 Sensor Controller, Dash Display, and Switch Panel in one!
Wideband O2 Senser Controller: The NanoPRO is compatible with 5 different wideband O2 sensors (Bosch 4.2, Bosch 4.9, Bosch 5.2, NTK ZFAS, and NTK Wideband O2 Sensor. The NanoPRO keeps your O2 sensor at the optimal temperature for accurate readings with 3 configurable heating modes; normal, fast, and current limited, in addition to auto startup. Additionally, the NanoPRO has an extended wideband reading scale with advanced hardware for fast and precise readings (reading range can reach values slightly lower than 0.21 λ).
Dash Display: With a 2” color touchscreen, the secondary display gauge function allows you to display information such as oil pressure, fuel pressure, boost, RPM, engine temperature, and more with the ability to configure up to 5 custom screens.
Switch Panel: The touchscreen display offers switch panel style button capability via CAN bus connection to your FuelTech ECU, providing more functionality without using an analog input.
The NanoPRO is IP67 rated (when properly connected to the harness), making it perfect for marine, off-road, and automotive applications.
