Important Compatibility Information:
- This package supports 2018-2019 E41 L5P ECM-equipped trucks.
- 2017 and early-2018 L5P trucks are technically supported by EZ Lynk, however EZ Lynk does not unlock the ECM. Trucks with a build date of February 2018 or later should support ECM unlocking through EZ Lynk.
- If your 2017 or early-2018 L5P ECM has already been unlocked using the HP Tuners Upgrade Tool (not the OBD unlock), it should be compatible with EZ Lynk tuning support.
