Notes

To effectively tune the L5P/L5D trucks you will need;

• HP Tuners TDN App: You must use the Tune Delivery Network (TDN) app with the Invite Code TLWN-3194.
• Hardware Requirement: This platform is only supported via MPVI4 (or RTD4) devices. Older MPVI2/3 units are not compatible with the Global B architecture.
• ECM Upgrade Service: Tuning the 2024-2026 L5P requires an unlocked E42 ECM. If your truck is not already upgraded, you must purchase the optional add-on 2024-2026 Duramax GM E42 ECM Upgrade Service. This is a "send-in" service that requires you to ship your truck's original ECM to HP Tuners for unlocking. This service is sold separately and is mandatory for the tuning process.
• Optional TCM Tuning: To fully optimize your drivetrain, we recommend the 2019+ GM T93 TCM Upgrade Service (Global B). This allows for custom transmission tuning to ensure crisp shifts and transmission longevity. This is a separate "send-in" service and requires an additional 4 Universal Credits to license the TCM.
• CAN Bus: A DEF CAN bus plug is not required; however, a 2020+ L5P DEF connector can be used with slight trimming for a clean install.
• Theft Lights: Dashboard messages and theft lights are normal and expected while the HPT device is connected or logging.
