GM Diesel E41 ECM/PCM Unlocking Service for HP Tuners
Coming Soon
Unlock the full tuning potential of your GM Duramax with our upcoming E41 ECM/PCM Unlocking Service. This service will allow you to use HP Tuners to read, write, and calibrate your E41-equipped diesel vehicle — safely and effectively.
What We’ll Offer
Many late-model GM diesel trucks are equipped with the E41 ECM, which comes factory-locked and inaccessible to tuning software like HP Tuners. Our specialized unlocking service will provide a secure and reliable way to unlock these modules for tuning access.
Supported platforms will include:
-
2017+ Silverado and Sierra 2500HD/3500HD with L5P Duramax
-
2020+ GM HD trucks with newer E41 variants
-
Other GM diesel applications using the E41 ECM
If you’re unsure about compatibility, feel free to reach out before sending in your module.
How It Will Work
-
Remove your E41 ECM from the vehicle.
-
Ship it to us using your preferred carrier.
-
We’ll perform a safe, professional unlock using industry-grade tools.
-
Your ECM will be returned ready for HP Tuners access.
Please Note: Some E41 modules may require the PCM cover to be carefully removed during the unlocking process. This is standard and does not affect functionality, but cosmetic signs of removal may be visible.
Turnaround time: Most modules are unlocked and shipped back within 1–2 business days of arrival.
