This new unit that combines the 6010 and 6012 into one unit has been made better with the fact Holley bought MSD Performance. The new circuitry has several new features such as individual cylinder timing adjustments, and the ability to program the unit via a USB cable and not having to turn your ignition on and off to get it to power on. It has a lot more compatibility with crank and cam combos (gen3 and Gen4 stuff being mixed such as a gen 3 3 bolt cam in a Gen4 block that has had DOD/VVT removed for reliability and racing). You can now use a 58x crank with either a 1x or 4x cam gear. And both harnesses are already included to save you time and money.
