E42 Unlock Service:
2024–2025 L5P ECM Unlock Service (Included in Kit)
Unlock the full tuning potential of your 2024–2025 L5P Duramax with this mail-in ECM unlock service, now available as part of our complete tuning kit. This is the required upgrade for GM’s new E42 ECM platform and is powered by HP Tuners, the industry leader in custom tuning solutions.
By unlocking your ECM now, you’ll be fully prepped for custom tuning the moment it becomes available—no delays, no waiting.
Please note: Since this is a brand-new unlock service, processing times may exceed the usual 1–3 business days. We recommend sending in your ECM early to beat the rush.
This unlock service is a core component of the full tuning package and is included with your purchase. Just mail in your ECM and we’ll handle the rest.
Note: Spare ECMs will NOT BE ACCEPTED, no exceptions. Only the original ECM from your vehicle is acceptable for this service.
ECMs with broken “LOCKING” tabs or connectors WILL NOT be accepted for upgrades.
How do I get started ?
How the Process Works – Simple, Fast, and Fully Remote
Once you place your order, a member of our team will reach out within one business day (Monday–Friday) to gather your vehicle details and begin processing your order. Please note: weekends are not included in the 24-hour window.
After we receive your information, you’ll receive step-by-step instructions to ship your ECM to us for the required unlock service.
ECM unlocks typically take 1–3 business days, but due to high demand, processing times may be longer. We strongly recommend sending your ECM in as early as possible to avoid delays.
While your ECM is being unlocked, we’ll ship all hardware and components directly to your door, so you’ll be ready to go as soon as it’s returned.
Once you receive your unlocked ECM, we’ll remotely flash your tune before any parts are installed, ensuring everything is configured and ready before the teardown process begins.
To complete the tuning process, you’ll need an HP Tuners MPVI3 device. Once it arrives, simply register it online and sync your 8 Universal Credits directly from HP Tuners. These credits are required to license your VIN and the upgraded ECM in order to enable remote tuning.
After installation, you’ll receive free remote retuning support as part of our lifetime support package—that means unlimited tune revisions at no additional cost.
Everything is handled 100% remotely. All you need is a Windows laptop and a reliable Wi-Fi connection.
