ECU Tuning

After all the hardware is installed, it’s crucial to tune your ECU for the turbo setup:

  • Install the ECU tuning software provided with your turbo kit.
  • Follow the software instructions to adjust fuel maps and boost levels.
  • Ensure the tuning is suitable for the 7-10 PSI boost range.

Final Checks and Testing

Before starting the engine, perform these final checks:

  • Double-check all connections and fittings.
  • Refill engine oil and coolant.
  • Reconnect the battery.

Starting the Engine

With everything in place, it’s time to start your RX-8:

  • Turn the ignition and let the engine idle for a few minutes.
  • Check for any leaks or unusual noises.
