- Fuel Rail and Injector Connections: Connect the included fuel rails to the injectors, ensuring proper seating and connections. Connect the fuel lines to the fuel rails (note: fuel pump and lines are not included and must be sourced separately).
- Wiring Harness Connections: Connect the wiring harness to the appropriate sensors and power sources. Refer to the FiTech wiring diagram for detailed instructions on connecting power, ground, ignition, and the oxygen sensor.
- Oxygen Sensor Installation: Install the provided oxygen sensor into the exhaust system using the included clamp and weld bung if necessary.
- Coolant Temperature Sensor (CTS) and Intake Air Temperature (IAT) Sensor: Install the CTS into the designated location on the engine and the IAT sensor into the intake manifold.
- Display Connection: Connect the 4.5-inch color touchscreen display to the ECU using the provided cable.
- Initial Setup via Display: Turn on the ignition (without starting the engine) and follow the prompts on the touchscreen to input basic engine parameters such as engine size, number of cylinders, and target idle RPM.
- First Engine Start: Ensure all connections are secure and there are no fuel leaks. Start the engine. The self-tuning ECU will begin to learn and adjust fuel delivery.
- Monitoring and Adjustment: Use the 4.5-inch display to monitor engine parameters and make any necessary adjustments as the system learns. Refer to the FiTech documentation for advanced tuning options.
