Step-by-Step Installation Process
Step 1: Disconnect the Battery
Safety is paramount when working on your vehicle. Begin by disconnecting the negative terminal of the battery to prevent any electrical accidents during the installation.
Step 2: Remove the Factory ECU
Locate the factory ECU, which is typically found under the dashboard on the driver’s side. Remove any panels or covers to access it. Disconnect the wiring harness from the ECU and unbolt it from its mounting location. Carefully remove the ECU from the vehicle.

Step 5: Connect the Power FC Commander
The Power FC commander allows you to tune your engine in real-time. Connect the commander to the Power FC unit and find a convenient location to mount it inside the vehicle.
Step 6: Reconnect the Battery
Once everything is connected and secured, reconnect the negative terminal of the battery. This will power up the Apexi Power FC and the commander.
Step 7: Initial Setup and Tuning
Turn on the ignition and check that the Power FC is functioning correctly. Use the commander to navigate through the settings and make any necessary adjustments. It is recommended to consult a professional tuner to achieve optimal performance and ensure your engine runs smoothly.
