Unlock the full tuning potential of your 2020–2022 LM2 3.0L Duramax with our E46 ECM Send-In Service. Designed for Chevy Silverado and GMC Sierra models using the E46 ECM, this service unlocks your module and enables full tuning access — without requiring any physical modification or in-shop visit.

 

🔧 Service Features:

 

  • Send-In Process: Ship us your ECM — we unlock and upgrade it, then return it ready for use.

  • Fast Turnaround: Minimal downtime with efficient processing and return shipping.

  • No Extra Programming Needed: No crank or IMMO relearn, no “Replace ECM” step required.

  • Advanced Tuning Capability: Once unlocked, your ECM supports full read/write functions with compatible tuning software and hardware.

 

⚠️ Not compatible with E66 ECMs used in some late 2022+ models.

 

This is the ideal solution for tuners or DIY users looking to enable advanced tuning functions from home — without risking damage to the ECM.

 

*For off-road use only.*
