This device allows custom tuners to develop their own files for a variety of vehicles & makes. The EZ Lynk platform gives full control over their own content & the vehicles’ parameters. Tune profiles are stored and shared through a Cloud-based system, which allows for easy access and convenient updating. The EZ Lynk platform can tune multiple trucks with one device (with the purchase of additional support packs). It also gives the ability to do your own adjustments, but experience with such is recommended.
