The ScienceofSpeed AEM Infinity Engine Control Unit (ECU) & Harness System for 1991-94 NSX is a programmable plug-and-play engine management system that allows total standalone control of fuel, ignition, VTEC, along with other engine functions based on the advanced AEM Infinity ECU. The system completely replaces the factory ECU & throttle body assembly.
The AEM Infinity ECU features a latest generation 32 bit 200 MHz processor capable of processing eight or more times faster than comparable engine management systems. This processing power allows for a volumetric efficiency tuning platform with real time closed loop fuel calculations allowing for increased fuel and ignition control allowing engines to produce more power.
The plug-and-play electrical harness designed, tested, and built in house by ScienceofSpeed integrates to the factory engine and cabin harness without cutting required. The complete system can be installed and removed without modification to the vehicle. An easy-wire accessory & VTEC connector allows easy installation of various accessories using factory connectors.
Systems based on the AEM Infinity 506 and Infinity 708 are available. The AEM Infinity 506 features 6 dedicated injector and coil outputs and a single channel on-board wideband sensor controller. The Infinity 708 adds an additional on-board wideband sensor controller, and an increased number of inputs.
Note: factory traction control & cruise control is not supported. The AEM Infinity includes a built-in, easy to configure traction control system. The ScienceofSpeed system is compatible with the factory traction control switch, or may be used with a multi-position switch. The factory "traction control" status lamp is supported.
Note: due to the limited inputs / outputs of the Infinity 506, the Infinity 708 should be considered if the application requires extensive input / output control (FlexFuel, boost control, fuel pressure, etc.) Please click here for a chart detailing available inputs / outputs between the Infinity 506 and Infinity 708.
