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.

FT550LITE EFI System — 3010005613

FuelTech's FT550LITE is more than your standard aftermarket ECU offering electronic fuel injection, data acquisition, and power management. The FT550LITE is designed for engines with up to 12 cylinders, or up to 4 rotors, and features 14 programmable inputs and 24 outputs. Enjoy the wide range of functions offered by the FT550 at a reduced cost! If you are in the market for a powerful aftermarket ECU and do not need a touch screen display screen, the FT550LITE is the perfect fit. This model offers GearController (power-shifts), built-in accelerometer (G-meter) and gyroscope; in addition to PowerFT ECU line standard features such as sequential injection and ignition, O2 closed loop, active traction control, integrated BoostController, internal datalogger, progressive and PRO-Nitrous controls, electronic throttle control, drag racing features and more! IP67 rated for marine and off-road applications.

*The FT550LITE ECU does not include an LCD touchscreen display.

SparkPRO-3 (Nautical / Off-Road) — 3010012266

FuelTech’s SparkPRO-3 Nautical / Off-Road model is a high-energy inductive ignition module designed to be used with ignition coils without an igniter (dumb coils) specifically in marine and offroad applications. The SparkPRO-3 (Nautical / Off-Road) had a redesigned case, specifically designed to keep water and fine dust particles from damaging the ignition module. The module has 3 ignition outputs, each output may be connected to only one coil at a time, and is available in versions from 1 to 8 ignition outputs. It has a high voltage of up to 430V at the coil’s primary. SparkPRO ignition modules are compatible with any programmable ECU that has dwell control but cannot be used with a stock ECU.

• SparkPRO Manual

Features

• Redesigned sealed case and connector for watersports and harsh off road environments

• 3 ignition outputs

Technical Description

• Used only with “dumb” coils (coils without igniter)
• Each SparkPRO channel can be connected to only one coil at a time
• Compatible with any programmable ECU that has dwell control
• Cannot be used with stock ECU

• Plug and play with our watersports and off road harnesses
• Dimensions: 115 x 90 x 33mm

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.
