2020-2022 Ford 6.7L Powerstroke Tunning Instructions for Commander Tuner

Comprehensive Guide to Tuning Your 2020-2022 Ford Powerstroke 6.7L

Enhancing the performance of your 2020-2022 Ford Powerstroke 6.7L requires specific tools and procedures. Follow this guide to ensure a successful tuning process.

Essential Tools and Software:

  • Commander Unlock & Tuning Tool: Equipped with a Ford-compatible harness, this tool is crucial for accessing your vehicle's Engine Control Module (ECM) and Transmission Control Module (TCM). Note: The orange wire included in the kit is not required for this process.​

  • Commander Credits: For 2020-2022 Ford models, 8 credits are necessary to perform the tuning. Typically, the initial 8 credits are included with the Commander tool, but it's advisable to confirm this upon purchase.

  • Tuning Software: Specialized software tailored for your vehicle's specifications is required to apply the new tune.​

  • Autoflasher Software: Click here to download.​

Special Considerations for 2022 Models:

Owners of 2022 Ford Powerstroke 6.7L models have two tuning options:

  1. Single Tune File: This option provides an approximate increase of 30 horsepower.​

  2. Switch-On-The-Fly (SOTF) Tuning: To utilize SOTF functionality, replacing the existing ECM with a 2021 model year ECM is necessary. This modification allows seamless switching between different power levels during operation.​

Data Collection Steps:

After acquiring the necessary tools, use the Commander device to retrieve the following serial numbers:

  • ECM Serial Number: For 2020-2021 models, connect directly to the ECM connector; the serial number typically starts with "40." For 2022 models without an ECM swap, connect via the OBD port; the serial number usually begins with "37." If a 2021 ECM has been installed in a 2022 model, connect directly to the ECM connector; the serial number should start with "40."​

  • TCM Serial Number: For all model years, connect through the OBD port; the serial number generally starts with "59."​

  • Cable Serial Number: This number is found on the Commander tool's cable.​

Information Submission:

Compile the following details and email them in plain text format:

  • Order Number

  • Vehicle Identification Number (VIN)

  • Cable Serial Number

  • ECM Serial Number

  • TCM Serial Number

  • For pre-2022 SOTF tunes: Preferred idle sound (options include stock, rumble, or hiss)

Important: Accurate serial numbers are crucial. Discrepancies can result in the loss of tuning credits, necessitating additional purchases. Ensure all information is correct before submission.​

Processing Time:

Upon receiving your complete and accurate information, the creation of your tune files will commence, typically requiring 3-5 business days.​

Backup Recommendation:

It's advisable to perform a read of your ECM before applying new tunes. This action preserves your vehicle's original settings, allowing you to revert to stock configurations if necessary.

 

To ensure a smooth tuning process, please follow these steps to obtain and provide the necessary serial numbers:

  4. Load Tune File: Navigate to the location where you saved your tune file, select it, and click Open.
  5. Complete the Process: The writing process takes approximately 10 minutes. Once you see "Flash Complete", disconnect the Commander and reconnect any factory cables you removed.
  6. Test Drive: Take your vehicle for a drive to ensure everything is running smoothly.

Section F: Performing a KAM Reset (2020-2021 Models Only)

After loading your tune file, it’s crucial to perform a Keep Alive Memory (KAM) reset. Follow these steps carefully:

  1. Unplug Throttle Valve: Ensure the throttle valve is disconnected (refer to the provided image for location).
  2. Drive and Relearn:
    • Start at 1/4 throttle: Drive until all gears have shifted, then pull over, shift to park, turn off the vehicle, and open and close the driver’s door.
    • Repeat the process for 1/2 throttle, 3/4 throttle, and full throttle.
  3. Repeat if Necessary: If the vehicle doesn’t hold power at any throttle position, repeat the previous throttle level.
  4. Finalize: Once complete, reconnect the throttle valve if you’re using a single-tune file. For SOTF setups on 2020-2021 models, proceed to Section G.

Section G: Installing the SOTF Switch (2020-2021 Models with SOTF)

For vehicles equipped with SOTF (Switch On The Fly) capability, follow these steps to set up your switch:

  1. Choose Location: Find a suitable spot inside your cabin to mount the SOTF switch.
  2. Route Wires: Feed the switch wires through the rubber grommet on the driver’s side firewall and into the engine bay.
  3. Locate Sensor: Route the wires to the Charge Air Cooler (CAC) sensor at the front of the engine bay.
  4. Connect Wires: Insert the SOTF wires into the provided CAC connector (wire orientation doesn’t matter).
  5. Disconnect Factory Sensor: Unplug the factory CAC sensor and connect the SOTF connector to its harness.
  6. Secure Throttle Valve Sensor: Unplug the throttle valve sensor and tape it out of the way to prevent interference with moving parts.

Troubleshooting Tips

If you encounter errors during the process, such as "Not enough credits", it’s usually related to your internet connection or software version, not an actual credit issue.

  1. Check Internet: Ensure you have a stable connection. A wired connection is recommended.
  2. Update Software: Close and reopen the Autoflasher software to check for updates. Always use the latest version.

By carefully following these steps, you’ll ensure a seamless tuning experience for your Powerstroke!
