Description: This GDP Commander Programmer is a great fit for 2017+ GMC/Chevrolet Duramax and 2020 - 2021 Ford Powerstroke vehicles. It's similar to an MPVI3, using a load - file process and a credit system. You'll need 8 credits to flash the Powerstroke ECM. It plugs directly into your ECM when you buy the harness, enabling easy remote tuning. Important: It must be loaded through an HP Laptop, no exceptions. This package includes only the device and 8 credits, no tune files. Check the tuning tab for links to tune files. It also comes with the MD1CP006 Ford ECM harness (required for flashing). L5P owners need to buy GDPE41HRN separately. For Powerstroke owners, select your idle sound (hiss or rumble). Features: Flash 2020 - 2021 6.7L Powerstrokes via Bench Flash with single or SOTF Files. Flash a 2022 6.7L Powerstroke via OBD for level 1 file only. Do an ECM swap on a 2022 6.7L Powerstroke to a 2020 - 2021 ECM for Bench Flash. Unlock and flash an L5P ECM. Apply custom tuning from home without shipping out the ECM, so no wait time! Tuning: It has POWERSTROKE SUPPORT PACKAGE and DURAMAX SUPPORT PACKAGE. Notes: If you need more credits, click here. Buy the right harness for your truck (Duramax: GDPE41HRN; Powerstroke: GDPCOMM2000). The 22 Powerstroke needs a 2020 - 21 ecm for egr removal and power boost. Installation: You'll need GDP Commander Software, GDP Commander Instructions, and the latest Commander/Autoflasher Software Download.

Using the GDP Commander Programmer is quite straightforward. First, make sure you have an HP Laptop as it's a must - have for loading the programmer. You'll need 8 credits to flash the Powerstroke ECM. If you run out of credits, just click the provided link to get more. When you want to start the tuning process, if you have a Duramax, you'll need to purchase the GDPE41HRN harness. For Powerstroke, get the GDPCOMM2000 harness. Then plug the programmer directly into your ECM with the harness. For 2020 - 2021 6.7L Powerstrokes, you can use Bench Flash with single or SOTF Files. If you have a 2022 6.7L Powerstroke, you can only use OBD for a level 1 file, or do an ECM swap to a 2020 - 2021 ECM and then use Bench Flash. For L5P, you can unlock and flash the ECM. One of the great things about this programmer is that you can apply custom tuning from home, so you don't have to ship out your ECM and wait. Remember, if you own a Powerstroke, you can select your idle sound, either a hiss or a rumble. As for maintenance, keep your HP Laptop in good condition as it's crucial for the loading process. Also, make sure to download the latest Commander/Autoflasher Software to ensure smooth operation.
