HOW TO USE:

• Preparation: Disconnect the negative battery terminal. Remove the existing carburetor and intake manifold from your engine. Clean the engine block surface thoroughly.
• Intake Manifold Installation: Install the FiTech intake manifold onto the engine block, ensuring proper gasket placement and torque specifications.
• Throttle Body and Fuel Rail Installation: Mount the FiTech throttle body onto the intake manifold. Install the fuel rails and injectors onto the intake manifold, connecting the fuel lines as per the manual.
• Sensor Installation: Install the included oxygen sensor into the exhaust system, as well as the MAP (Manifold Absolute Pressure) and IAT (Intake Air Temperature) sensors in their designated locations.
• ECU Mounting and Wiring: Mount the ECU in a suitable location away from heat and vibration. Connect the wiring harness to the ECU, sensors, injectors, and other necessary components, following the wiring diagram provided.
• Handheld Controller Connection: Connect the handheld controller to the ECU using the provided cable.
• Initial Setup via Handheld Controller: Turn on the ignition (without starting the engine) and use the handheld controller to input basic engine parameters such as engine size, number of cylinders, and fuel type.
• Fuel System Setup (Separate): Install a suitable high-pressure fuel pump, fuel lines, and fuel pressure regulator (not included in the kit) according to the manufacturer’s instructions. Ensure the fuel system is properly primed and checked for leaks.
• First Start and Self-Learning: Start the engine and allow it to run. The self-learning function will begin to adjust fuel trims based on the oxygen sensor readings. Monitor engine parameters on the handheld controller.
• Fine-Tuning (Optional): After the self-learning process has had time to adapt, you can use the handheld controller to make further adjustments to fuel curves, idle settings, and other parameters if desired.

BENEFITS OF USING THE FITECH 750HP VORTEC EFI 4150 FLANGE ULTRA BRILLIANT TMAP (30-21-610):
