how to high idle a 6.7 powerstroke

High idling a 6.7 Powerstroke diesel engine can be done for various reasons, such as warming up the engine faster in cold weather or providing power for auxiliary equipment like air compressors. However, it’s important to note that making modifications to your vehicle’s engine operation may affect its warranty or emissions compliance, so proceed with caution and be aware of any legal implications. Here’s a general guide on how to high idle a 6.7 Powerstroke:

Method 1: Using a High Idle Kit (Recommended)

  1. Purchase a High Idle Kit: Invest in a high idle kit designed for your specific Ford 6.7 Powerstroke model. These kits are designed to provide safe and controlled high idle functionality.
  2. Read the Kit Instructions: Carefully read and follow the instructions provided with the high idle kit. Different kits may have specific installation and operation procedures.
  3. Install the High Idle Kit: Typically, high idle kits are installed by connecting to the vehicle’s electronic control system. This may involve plugging into the OBD-II (On-Board Diagnostics) port or tapping into the throttle position sensor.
  4. Set the Desired RPM: Many high idle kits allow you to set the desired RPM (revolutions per minute) for the high idle. This can usually be done using a control knob or switch provided with the kit.
  5. Engage the High Idle: Once the kit is installed and the desired RPM is set, engage the high idle according to the kit’s instructions. This often involves flipping a switch or turning a knob to activate the feature.
  6. Monitor the Engine: Keep an eye on the engine and monitor the RPM to ensure it stays within the desired range. Avoid setting the high idle at excessively high RPMs to prevent engine damage.

Method 2: Using a Tuner (Advanced)

Note: Modifying your vehicle’s engine using a tuner can have significant consequences for warranty, emissions compliance, and the overall performance of the engine. Use this method with caution, and be aware of any legal implications.

  1. Purchase a Tuner: Obtain a performance tuner or programmer that is compatible with your Ford 6.7 Powerstroke model. These devices allow you to adjust various engine parameters.
  2. Install the Tuner: Follow the tuner’s installation instructions, which usually involve connecting the device to the OBD-II port or the vehicle’s computer.
  3. Access Tuning Options: Access the tuning options provided by the tuner. Look for settings related to engine idle speed.
  4. Adjust Idle RPM: Use the tuner to increase the engine idle speed to the desired RPM. Be cautious not to set it too high, as excessive RPM can harm the engine.
  5. Save the Changes: Once you’ve adjusted the idle speed, save the changes using the tuner’s interface.
  6. Activate High Idle: Engage the high idle setting using the tuner. This can typically be done through the tuner’s menu or settings.
  7. Monitor and Test: Monitor the engine’s RPM to ensure it stays within the desired range. Test the high idle functionality to make sure it works as intended.

Always check your local and state regulations regarding vehicle modifications, emissions compliance, and the legality of high idling. Additionally, be aware that making modifications to your vehicle’s engine may void warranties, so consult with your dealership or manufacturer if you have concerns about warranty coverage.
