ScienceofSpeed AEM Series 2 EMS - NSX, 1995-05

The ScienceofSpeed AEM Series 2 Engine Management System (EMS) for 1995-05 NSX is a programmable plug-and-play engine management system that allows total standalone control of fuel, ignition, VTEC, along with other engine functions.

The Series 2 EMS offers increased processor speed, enhanced sensors stability, USB connection, FlexFuel tuning, engine protection features, and other benefits. Retains the factory ECU for throttle body and dashboard control.

Note: factory traction control is not supported. The AEM EMS has a limited engine acceleration traction control system (wheel speed sensors are not used) to calculate loss of traction. Requires individual vehicle setup and configuration. If you are looking for an engine management system with built in wheel speed based traction control, please click here.

This engine management system is for off road use only, and is not intended for polution controlled vehicles.

• installs into NSX in minutes with plug-and-play installation including professionally built plug-and-play harness
• no cutting or modification of the factory electrical harness required - the car can be reverted back to factory at any time.
• full fuel, ignition, VTEC, and rev limiter control
• start up NSX-specific calibrations included for naturally aspirated, supercharged, and turbocharged applications - includes FlexFuel and engine safety options.
• compatible with factory sensors
• compatible w/ factory coolant gauge
• compatible with Microsoft Windows and includes USB data port
• onboard memory for data logging with out laptop connected
• system is full enabled - free software & firmware updates
• compatible w/ boost controllers allowing turbocharger boost control, progressive gear or speed based boost control, etc.
• compatible with a number of telemetry products including the AEM Serial Gauge, gaugeART Video Gauge Adapter, and race dashes (such as Race Technology Dash2Pro).
• compatible with factory emissions controls
• new: FlexFuel (E85) tuning - allows the engine to operate seamlessly between any amount of gasoline or ethanol (E85)
• new: advanced engine protection features - allows the EMS to automatically limit the engine speed if coolant temperature, AFR, fuel pressure, oil pressure, or oil temperature limits are exceeded!
• new: plug-and-play harness allows a number of accessories to be added including wideband oxygen, FlexFuel, fuel pressure, oil pressure, and oil temperature sensors.

• wideband oxygen sensor (required): Use one for single turbocharged applications or two for naturally aspirated, supercharged, or twin turbocharged applications.
• MAP sensor (required for FI): for forced induction applications (supercharged, turbocharged) a separate MAP sensor is required and sold seperately. The map sensor ScienceofSpeed recommends comes as a kit, and is sold on this page. The factory MAP sensor is retained for factory ECU function.
• electronic boost control solenoid: for turbocharged applications, the AEM EMS can control boost with a wastegate electronic boost control solenoid.
• FlexFuel (E85) sensor: sensor allows for FlexFuel tuning.
• Air Intake Temperature sensor: recommended for forced induction where the open element sensor is more accurate than the factory closed element sensor.
• additional sensors: additional sensors can be added for engine protection features or for viewing on telemetry products such as gaugeART.
• telemetry products: the AEM EMS is compatible with gaugeART Video Gauge Adapters and Race Technology Dash2Pro race dashes.
