Important ECM Unlock Note (2017–2018)
ATTENTION: Some 2017–2018 trucks with ECM part number ending in 12676723 must be bench unlocked by EZ Lynk (ECM shipped in). These are not currently flashable through normal EZ Lynk flashing.
If the ECM won’t unlock using the EZ LYNK AutoAgent 3, you’ve basically got two options that are not included in this purchase:
- Send the ECM to EZ LYNK directly for the unlock/service, or
- Buy HP Tuners hardware (MPVI3 or MPVI4) + the HP Tuners unlock kit, and purchase 6 HP Tuners credits to complete the unlock.
EZ Lynk releases firmware updates regularly, so compatibility improvements can change over time.
If you have a flashing/linking issue, EZ Lynk support is: 877-207-5530
