Custom engine calibration for the 2011–2016 LML 6.6L Duramax — engine-only tuning for the CP4-equipped generation, dialed in for power and fuel efficiency without touching the TCM.
What's included
- Custom VIN-matched LML ECM calibration with multiple switchable power levels
- Fueling, timing, boost, rail pressure, and EGT calibration
- Datalogging support for ongoing calibration refinement
How it works
Files are delivered via EFI Live FlashScan V2. Your calibration is built from your stock ECM file and VIN-locked. A FlashScan V2 device is required to flash the ECM.
Support tiers
- Limited (4 Weeks): Four weeks of revision rounds; tune stays on your tool after the window closes.
- Full (Lifetime): Unlimited revisions and lifetime access.
Requires an EFI Live FlashScan V2 device. Engine tune only — does not include Allison TCM calibration.
Calibrations are developed for motorsport and off-road use. Verify local regulations before use on public roads.
