I want to tune an Additional Truck with my EFi Live AutoCal - Additional VIN License
AutoCal V3 VIN License Management
For customers using the EFi Live AutoCal device, it is possible to expand the number of VIN licenses to tune additional ECUs. Initially, each AutoCal device comes with one pre-configured VIN license.
If more VIN licenses are required, Tuner Depot can assist with increasing your device's VIN license slot capacity, allowing for additional VIN licenses to be activated.
Important: Before validating Serial and Auth Codes, you must increase the VIN license slot capacity.
