ScienceofSpeed AEM Infinity 506 Engine Management System - S2000, 2000-05


The ScienceofSpeed AEM Infinity Engine Management System for the 2000-05 Honda S2000 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 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 ScienceofSpeed AEM Infinity System for S2000 is a complete plug-and-play system. The plug-and-play mounting panel and electrical harness was designed, tested, and is built in house by ScienceofSpeed. The compact assembly mounts to the factory ECU mounting location and eliminates the problem with the AEM harness solution that is bulky making installation behind the factory panel difficult and does not fix the ECU in place.


  • 4 independent sequential injectors
  • 4 independent ignition coils
  • 7 available analog inputs (fuel pressure, oil pressure, boost position switch, traction control switch, etc)
  • 2 available digital inputs (FlexFuel, traction control pulse converter input, etc)
  • 1 available temperature input (oil temperature)
  • 2 switched LS outputs (boost control, MIL (dedicated), etc)

This product is designed and intended for Racing Competition Only:
This product is not designed or intended for pollution controlled vehicles. In the United States, the use of this product is regulated by the Environmental Protection Agency under the Clean Air Act. Use of this product must be used in accordance with the Clean Air Act, and any other Federal, State, or Local mandated regulations. The use of this product must only be used on a vehicle in sanctioned competition events and may not be used on public roads, streets, or highways. A Vehicle Compliance Waiver is required for all products marked "Racing Competition Only".  This product replaces the factory ECU, so the factory OBD system is not longer functional.


  • Advanced ECU with latest generation processor supports volumetric tuning with closed loop fuel & ignition control.
  • Compact assembly with professionally constructed plug-and-play harness with epoxy potted connectors.
  • Mounting panel allows installation to factory ECU mounting location.
  • High quality plug-and-play UEGO sensor harness included.
  • 16 position accessory wire harness and connector included for easy wiring of engine accessories in the engin bay.
  • On-board wideband oxygen sensor controller for precise closed-loop fuel feedback (sensor available separately).
  • Capable of FlexFuel (E85) tuning.
  • Engine protection based on engine coolant, oil temperature, oil pressure, AFR, etc.
  • Advanced configurable traction control system with additional sensor.
  • Completely replaces factory ECU.


  • AEM Infinity 506 ECU
  • fully assembled and professionally constructed plug-and-play electrical harness w/ epoxy potted connectors
  • fully assembled mounting panel
  • wideband sensor electrical harness w/ 1200 deg F heat resistant sleeving
  • sealed connector, terminals, and seals for accessory connector
  • 30+ page with instruction manual with step by step photos instructions gets you up and running quickly
  • ScienceofSpeed-tuned base calibration allows you to start and run the engine within minutes of installation


  • wideband sensor: the AEM Infinity features one on-board wideband controller. LSU 4.2 wideband sensor is required (sold separately above & discounted when purchased with ECU).
  • traction control: the ScienceofSpeed Wheel Speed Sensor Pulse Converter allows the AEM Infinity to work with the factory wheel speed sensor to allow the sophisticated built-in AEM Infinity traction control system to be used. A switch can be added to turn traction control on or off - and an available LS or the MIL lamp can be used to indicate traction controls system position and actual wheel slip occurring. Sold separately above. More info.
  • fuel pressure sensor: highly recommended. Closed loop fuel calculations can be precisely calculated by the AEM Infinity with less reliance on wideband sensors with fuel pressure sensor input. Optional sensors sold here & installation kit sold here.

  • MAP sensor: the AEM Infinity is compatible with the factory MAP sensor, which has a range up to 10 PSI. For higher boost applications, a higher capacity MAP sensor is required. ScienceofSpeed offers this 3 BAR plug-and-play MAP sensor.
  • oil pressure & oil temperature sensors: can be added for additional engine safety functions. Pressure and temperature sensors sold separately.
  • electronic boost control solenoid: for turbocharged applications, the AEM Infinity can control boost with a wastegate electronic boost control solenoid. Sold separately here.
  • FlexFuel (E85) sensor: sensor allows for FlexFuel tuning. Sold separately here.
  • telemetry products: the AEM Infinity is compatible with gaugeART Video Gauge Adapters and Race Technology Dash2Pro race dashes.
