EFI Live Autocal V3 with custom tuning 

With 512MB storage for tune and log files, capacity of 600 VIN Licenses, and file transfer times up to 10 times faster than AutoCal V2, AutoCal V3 delivers significant hardware advancements to the tuning market.

AutoCal V3's built in USB drivers, field upgradeable firmware, and the custom menu system makes supporting remote customers a breeze.

Supporting GM, Dodge Cummins and Cummins Heavy Duty protocols on the one device, a future update for AutoCal V3 will enable license transfers between FlashScan and AutoCal V3 devices where the device license numbers match. AutoCal V3 can be used by tuners with FlashScan V3 (not yet available), FlashScan V2 or FlashScan HD.

AutoCal V3 User Guide is now available to assist both tuners and end users. The AutoCal V3 label template is also available for tuners who wish to rebrand AutoCal.
