Description: Make the switch to fuel injection. Now you can get the horsepower and drivability of a tunable EFI system for your marine application with these Holley Hirel Commander 950 marine conversion kits. These kits use speed density technology, which means they improve performance at cruising rpms, as well as throttle response. They also accept engine modifications like bigger cams, headers, etc., but the big deal is that these systems are fully programmable. They give you total control over fuel and timing curves via a laptop computer. These Holley engine management system kits contain the Commander 950 ECU, and a wiring harness and sensors, where applicable, that you'll need to make a customized fuel injection installation.
