Read each step carefully before making any modifications to your truck.
- You do not require the TDN app. Follow the instructions provided below. *
L5P tuning procedure with a new ECM:
Start with all emissions components installed and operating without any codes or error messages. Ensure that the DEF level is not low. For model years 2017-2019, it’s crucial to verify that the soot levels are below 70% before proceeding.
- We ship all the parts to you.
- Install the latest version of the VCM Suite BETA software. Make sure to check for updates regularly whenever you open the software.
- Connect the MPVi3 device to your laptop and launch VCM Scanner.
- While the factory ECM is still in place, save an info log.
Refer to the provided instructions for creating an info log.
Next, initiate the ECM swap process by navigating to Vehicle > Controls and special functions > System > Replace ECM.
- When prompted, install the new ECM. Before disconnecting the ECM, ensure to disconnect the battery grounds. Always take caution when inserting the connectors into the ECM, as the pins are delicate and damaging them can lead to issues.
- Proceed to complete the ECM swap process within VCM Scanner.
- Once the ECM swap process is complete and the NEW UNLOCKED ECM is installed (or your stock ECM is unlocked), proceed to download the .hpt read file. Navigate to VCM Editor, close the file, and select “Read Entire” under the ECM section. Ensure to select “Do not read” under the TCM section if you’re not tuning the transmission control module. Click “Read” and save the file with the name “[ORDER #]__[VIN]”.
- If you’re also replacing the TCM, revisit steps 4-7, select “Replace TCM”, follow the prompts, and save the TCM read file. Include this file along with other files/info in step 9. If you’re not tuning the TCM, proceed to step 8.
- Now that the read file is saved, also save the info log.
Instructions for creating an info log can be found here.
- Email info@thedpfdelete.com with the info logs (those using a new ECM will have two info logs, those unlocking the factory ECM will have one info log), along with the vehicle VIN, order number, and “read file”. Upon receiving all necessary files, we will proceed to transfer them to tuning and add the credits to your MPVI.
- Now, you can reinstall the factory ECM to continue using the vehicle in its stock form. [DO NOT REMOVE EMISSIONS YET]
After TheDPFdelete receives the files and information mentioned above, we will create the tune within 3-5 business days and send it back to you. Do not remove any emissions systems until the delete tune is loaded. If you remove the emissions while the factory tune is loaded, you will encounter emissions-related messages displayed on your dashboard, and you will need to reinstall the emissions to remove these messages. We are not responsible for these error messages and cannot offer support for this particular issue.
After getting the files, proceed with the following steps:
- If you reinstalled the original ECM after completing step 9, reinstall the new ECM. Then, open VCM Editor, connect the MPVI3 to the laptop (not the truck), and use VCM Editor to resync the MPVI interface (Help > Resync Interface).
- Ensure that no tune file is loaded by closing the file using the Folder icon on the top left menu bar.
- Open one of the tune files we sent you (ctrl+O) [either VATS on or off]. Then, connect the MPVI to the OBD port.
- Click “Write Vehicle” – change the option to “Write entire” instead of “Write calibration” and confirm.
- Turn off the ignition.
- If you have a TCM tune, install it now using the same process. If not, start the truck and proceed with the crank relearn procedure:
- Start the engine and allow the engine coolant temperature to heat up to above 170°F (This may take some time, so please be patient as failing to reach the proper temperature will cause the procedure to fail).
- Use VCM Scanner to initiate the crank relearn. (Navigate to Controls and special functions > Crank relearn).
- Gradually increase the engine speed until the fuel cutoff (4000-5000 RPM), then release the throttle. Allow the engine to return to idle speed, then turn off the ignition for at least 15 seconds. Turn the ignition back on, and the “crank not learned” error should now be resolved.
- With the engine turned off, disconnect the battery ground wires before proceeding to remove the emissions equipment. It is crucial to remove the ground cables before unplugging the NOx sensors and DEF tank.
- Carefully install the CAN plugs, ensuring they are fully seated to prevent potential issues. Proper resistance is required for these connections, so it is necessary to apply dielectric grease to all connections. Even open connectors should be coated with dielectric grease and securely taped to maintain cleanliness and dryness.
- After removing the parts, reconnect the battery grounds and start the truck. If you have followed these instructions properly, you should not encounter any emissions codes or CELs.
Notes:
*ALWAYS use a battery charger capable of supplying a steady 10 amps or more.
** When opening VCM software, it may open the last file used. Always close the file when opening VCM software using the top-left Folder icon.
*** In some cases, the VIN may not register properly. If you have finished tuning and your VIN is not showing up, you can use VCM Scanner to change the VIN in all caps (Vehicle > Controls and special functions > System > Change VIN). If this method fails, go back to VCM Scanner, select “Vehicle” from the top menu bar, then “Diagnostics,” and finally “Clear DTCs.” Clear them even if there aren’t any.
****The current VCM Suite Beta software requires a specific version of .NET. If you encounter errors while working with the software, check your .NET version or update it from the HP Tuners Downloads section (found under the link to the BETA software).
*****Always connect the MPV device to the computer before connecting it to the truck.
Due to our current tuning demand, please expect a processing time of 1-3 business days from the receipt of your base files to when we send you the modified file.
If you are a shop installing this for a customer, we highly recommend scheduling two appointments. The first appointment should be to perform the ECM swap, retrieve the info log, and read the file needed for tuning. The second appointment can then be scheduled to load the tune and complete the rest of the parts installation.
******If emissions were disconnected before tuning, you may receive a Service Emissions message on the dashboard. Additionally, if the DEF tank was low during tuning, you might encounter a Low DEF light on the dashboard afterward. To prevent these issues, ensure the DEF tank is at least 1/4 full. For 2017-2019 model years, confirm that soot levels are below 70%; if they exceed this threshold, a force regeneration may be necessary before tuning.
*******Our tuning pricing does not include revisions necessitated by customers submitting incorrect files. The read file and info log must be obtained with the NEW ECM. Failure to adhere to these instructions and instead reading the factory ECM will result in the tune being compatible only with that ECM. In such cases, you may need to send it in for unlocking or purchase another tune. It’s crucial to follow these instructions precisely. If you realize a mistake, contact us before submitting any files.
