I’d say the pros for the VMAC electronic engine is better cruise control, PTO speed control,  road speed limit for fleets, better cold start ability, less smoke, engine protection from low oil pressure/high coolant temperature , easier to calibrate speedometer for gear and tire size changes and the list goes on. On the negative side would be engine harness, sensors and ECMs that could randomly fail leaving you on the side of the road. Also then inability to easily turn the fuel and rpms up for more HP/speed.
