Sending the files for us to create your tune file

Now that all necessary fields are filled, open a new email addressed to info@thedpfdelete.com with the subject “Order number (insert your order number) Powerstroke Tune Request”.

Paste the information from your notepad into the body of the email, attach your read files, and send the email to us.

Please allow 1-3 business days for us to create and send your tune back to you. If you’ve purchased a TCM tune, please note that it will be sent in a separate email due to current email file size restrictions.

Section E

Writing your ECM tune file

  1. Begin by following the instructions outlined in Section B or C, depending on your truck’s model year, to establish the connection with your vehicle.
  2. Once connected, proceed by selecting either OBD > Write or Service Mode > Write, depending on the appropriate method for your truck (Service Mode for 2020-2021 models and OBD for 2022+ models). In the new prompt, choose the module you wish to flash (ECU for the engine computer and TCU for the transmission computer). Always start with the ECU if you’ve ordered both ECU and TCU tunes.
  3. Locate the saved tune file on your computer, select it, and then click Open.
  4. The writing process typically lasts about 10 minutes.
  5. After the flashing is complete, you’ll see a message indicating “Flash complete“. Click Cable > Disconnect, then reattach any factory cables you may have removed and take your truck for a drive!

Section F

KAM Reset Procedure – This must be done IMMEDIATELY after loading the tune file

  1. Ensure that the throttle valve is disconnected (Refer to the image below).
  1. Initiate the relearn process starting at a 1/4 throttle position. Allow the vehicle to shift through all gears, then pull over, shift to park, turn off the truck, and open/close the driver’s door.
  2. Repeat the relearn process at 1/2 throttle, 3/4 throttle, and full throttle positions.
  3. If power isn’t sustained at any throttle position, repeat the previous throttle position’s relearn process.
  4. Once the relearn process is complete, reconnect the throttle valve if you’re using a single-tune file on a 2022 ECM. If you’re employing SOTF on a 2020-2021 ECM, you can proceed to section G.

Section G

Wiring your SOTF switch (2020-2021 ECM running SOTF)

  1. Identify a suitable location within the cabin to mount the switch securely.
  2. Thread the wires through the driver’s side firewall rubber grommet into the engine bay.
  3. Once in the engine bay, guide the wires towards the front, reaching the Charge Air Cooler (CAC) sensor location.
  4. Insert the SOTF wires into the provided CAC connector; note that wire orientation is not critical.
  5. Disconnect the CAC sensor and attach the SOTF connector to the factory CAC harness.
  6. Unplug the Throttle Valve sensor and carefully tape the connector away from any moving components.
