Holley's HP EFI is one of the most capable standalone ECUs available today. Every parameter of your engine's tune can be modified via Holley's easy-to-use EFI software. The lb/hr fueling strategy is an industry first, making changes on the fly that much easier. Those features are just the beginning of the HP ECUs capabilities though; Controlling your turbocharged or nitrous-fed setup has never been easier!
