FT550 EFI System — 3010005496

FuelTech's FT550 is more than an ECU offering electronic fuel injection, integrated dashboard, data acquisition, and power management. The FT550 is designed for engines with up to 12 cylinders, or up to 4 rotors, and features 14 programmable inputs and 24 outputs. In addition to offering all of the features and functions of the FT450, including touchscreen display, 4 programmable display screens, customizable splash screen, sequential injection and ignition, O2 closed loop, active traction control, integrated boost controller, internal datalogger, progressive and PRO-Nitrous controls, odometers, drag racing features, the FT550 is loaded with additional features such as electronic throttle control, inclinometer gauge, integrated GearController with strain gauge sensor on the shifter for more efficient gear shift cuts, built-in accelerometer (G-meter), and gyroscope. The FT550 is housed in a high-quality ABS case and is IP67 rated for marine and off-road applications.

Ft450/550 4 Cylinder Universal A Harness — 2002006505

The FuelTech Universal 4 cylinder A harness is a great addition to any 4 cylinder build and can be used with both the FT450 and FT550 ECU’s in a complete plug and play style. It is to suit 4 injectors and 4 individual smart coils, wired in semi-sequential fuel injection and wasted spark ignition (full sequential requires the FT550 ECU and the 4 Cylinder Universal B Expansion Harness). It can be used with high or low impedance injectors; low impedance requiring the use of a peak and hold driver, high impedance requiring a peak and hold jumper harness (both sold separately). The harness is set up for either VR or Hall effect cam and crank sensors and includes 3 relays with built in fuses for main electronics, injectors and coils. The universal 4 cylinder A harness has a label for each connector and the insulation is heat, moisture and oil resistant.

• FT450/FT550 4 cylinder universal harness Manual

Technical Specifications:

• 4 EV1 injectors
• 4 Smart coils
• FuelTech Peak and Hold external drivers ready
• FuelTech WB-Nano O2 ready
• GM style intake air temperature sensor ready
• GM style engine temperature sensor ready
• 2 pressure sensors ready for fuel, oil / another 0-5V sensor
• Extra output connector for generic use
• Crank and CAM connectors (hall and VR options included)

This harness was designed for systems with up to 4 injectors, 4 smart coils and a FuelTech Wideband Nano O2 with Bosch LSU 4.2 sensor. It's setup to run semi-sequential or multipoint injection and wasted spark. It is already wired for use with a FuelTech Peak and Hold driver when using 4 low impedance injectors. When using high impedance injectors, a Peak and Hold driver is not needed and in this case, only a bypass connector is required (jumper included). There are 3 separate relays to power the whole system, separating the injectors and coils from the electronics. To activate coils and injectors relays the Blue#6 output must be configured as Fuel pump or RPM activation.

*This is only the A harness which is all the FT450 requires.
To use this harness with the FT550, the FT550 4 Cylinder Universal B Expansion Harness is required in order to use all of the extra inputs & outputs.

FT550 4 Cylinder Universal B Expansion Harness — 2002006600

The FuelTech Universal 4 cylinder B FT550 expansion harness compliments the Universal 4 cylinder A harness with the options to control up to 8 injectors staged sequentially, have direct connection for inbuilt gear controller as well as the additions to inputs and outputs. The harness comes with a relay with a built in fuse for power supply to the extra 4 injectors. The injectors are to be of high impedance only. The Universal 4 cylinder B harness has a label for each connector and the insulation is heat, moisture and oil resistant.
