Installation Steps
Step 1: Disconnect the Battery
Before beginning any electrical work, ensure the vehicle’s battery is disconnected to prevent short circuits or electrical shocks.
Step 2: Remove the Factory ECU
Locate the factory ECU in the driver’s side footwell. Remove the cover and disconnect the wiring harness from the ECU. Carefully remove the ECU from its mounting location.
Step 3: Install the HKS F-Con V Pro
Install the HKS F-Con V Pro in the same location as the factory ECU. Secure it using the original mounting points. Connect the wiring harness to the F-Con unit, ensuring all connections are secure.
Step 4: Connect Sensors and Inputs
Connect any additional sensors required for the F-Con V Pro, such as the wideband O2 sensor. Follow the wiring diagram provided with the unit to ensure proper connections.
Step 5: Reconnect the Battery
Once all connections are made, reconnect the vehicle’s battery. Ensure there are no exposed wires or loose connections.
Step 6: Initial Setup
Power on the ignition and follow the initial setup instructions provided by HKS. This may include setting the base fuel maps and ignition timing.
Tuning the HKS F-Con V Pro
Tuning is a critical step in maximizing the performance of your MR2 Turbo. Here are the key aspects to focus on:
- Fuel Maps: Adjust the fuel delivery across different RPM ranges to optimize performance and efficiency.
- Ignition Timing: Fine-tune ignition timing for better throttle response and power output.
- Boost Control: Set desired boost levels for your turbocharger to achieve the target horsepower.
- Air-Fuel Ratio: Monitor and adjust the air-fuel ratio for optimal combustion and engine health.
Using a Dyno for Accurate Tuning
