With maximized power, rugged design and unsurpassed flexibility, the Rockwell Collins Engine Control Unit (ECU) is simply the best solution for your engine control needs. And it can be customized to any target application ? aerospace, automotive/off-road, marine and power generation.

With the standard ECU, our engineers have maximized power and fuel economy targets across a wide range of operating and environmental conditions on both two- and four-stroke power plants. In addition, the unit gives you unsurpassed flexibility ranging from an adaptable mixture control for a variety of fuels, to a fully automated drive-by-wire and single-lever power controls solution.

Key Features & Benefits
*Self-monitoring: Closed-loop, real-time health and usage monitoring system assures the engine is operating within allowable limits; performs diagnostics and prognostics.
*Rugged: Performs in abnormal operating conditions.
*Adaptable: Compensates for engine wear and tear, ensuring allowable thermal limits at all times (CHT, EGT, TIT, coolant, oil, turbos, etc.).
