Improve Drivability, Fuel Economy, Power/Torque, Longevity in Marine Performance Engines

Drivability, Idling and Operating Quality – Engine Management Systems precisely deliver the proper amount of ignition timing, acceleration fuel, and operational fuel resulting in increased throttle response. Ignition timing and fuel dispersion can be modified per rpm, load and throttle position. This flexibility optimizes engine efficiency throughout every rpm and load range. Throttle movement, whether forward or backward, signals acceleration or de-acceleration maps. Initial start-up/ warm-up fuel maps ease starting. Idle and operating quality can be enhanced by the following functions:


- Distributing highly atomized fuel in precise amounts
- Phasing the fuel timing
- Using injector bias with multiple injectors
- Sequentially “trimming” fuel delivery per cylinder
- IAC motor
- Correction tables for air temperature, and water temperature
- Correct ignition timing
- Sequentially “trimming” each cylinder’s ignition timing
- “Dwell times” from CDI ignitions
- “Wasted spark” systems

Fuel Economy – Exact fuel control for every rpm and load value increases overall fuel economy from 15% to 20%. In addition, high fuel pressure injects intensely atomized air/fuel charges, which increase volumetric efficiency.

Power/Torque - Power gains on average are 20% from 0-3000 rpm, 10% from 3000 to 4500 rpm, and 5% at full throttle. The ability to manage accurate fuel distribution and ignition timing for every rpm range and load range enables impressive engine efficiency, resulting in higher power output.

Longevity – By eliminating engine inefficiency, EFI prolongs engine life. Over-fueling and misfiring dilutes the lubricating system with fuel, causing wear and friction on piston rings, bearings, camshaft, valve train and valve guides. Highly atomized fuel/air mixtures prevent “rich or lean” conditions, which cause engine deterioration. A smoother running engine has a lower mechanical deterioration rate.

Protection – Protect your valuable engine investment by having this engine management system “alarm” you. This always ensure the engine operating within parameters such as, voltage, air temperature, water temperature, oil temperature, water pressure, oil pressure, fuel pressure, ECU temperature, knock sensing, and excessive rpm.
