Minimum Software/Firmware: V5 Build 120 is required to use the Pro 600 with Holley EFI
The MSD Pro 600 has several unique features available when used with Holley EFI. The first is that the power output of the Pro 600 is adjustable via a table in the Holley EFI software. The second is that diagnostic data from the Pro 600 can be recorded in the Holley EFI for review. The only thing required to use these features is the CAN to be connected between the Holley EFI and MSD Pro 600.
