Engine Management Systems
Engine Management Systems




The Infinity EMS represents a quantum leap in technological capability over virtually all existing programmable engine management controllers available today and eases the tuning process for even the most sophisticated engine combinations. It is quite possibly the most advanced programmable engine controller available.

  • VE based tuning using airflow calculation models
  • Flex fuel compensation
  • Multi fuel strategy
  • Dual internal wideband controllers
  • Data logs 100 channels at up to 1KHz
  • Data logging playback with controls synchronization
  • Up to 12 peak and hold injector drivers
  • Up to 12 (0-5V) ignition outputs (igniter required)
  • Up to 6 analog temp inputs
  • Up to 17 analog voltage inputs
  • Two knock inputs
  • Up to 8 digital inputs
  • Up to 6 VR/Mag inputs
  • Up to 13 configurable outputs
  • One stepper control
  • 129 pin, fully sealed ECU enclosure and IP67 spec connectors



The Infinity-6 and Infinity-8h ECU, an affordable state-of-the-art engine control unit designed for four- and six-cylinder racing engines and V8 racing engines using high-impedance injectors. Extensive research and development was put into designing the Infinity-6/8h to ensure that it delivers an unmatched price point for this level of engine control.

  • VE based tuning using airflow calculation models
  • Flex fuel compensation
  • Multi fuel strategy
  • Internal wideband controllers
  • Data logs 100 channels at up to 1KHz
  • Data logging playback with controls synchronization
  • Up to 8 injector drivers
  • Up to 8 (0-5V) ignition outputs (igniter required)
  • Up to 3 analog temp inputs
  • Up to 9 analog voltage inputs
  • Two knock inputs
  • Up to 8 digital inputs
  • Up to 4 VR/Mag inputs
  • One stepper control
  • 80 pin, fully sealed ECU enclosure and IP67 spec connectors



A complete engine control system that plugs into the factory harness and uses the factory sensors. AEM’s Series 2 Programmable Engine Management System (EMS) is more powerful than its predecessor.

  • Plugs directly into the factory harness. No rewiring necessary.
  • Maps can be password protected by the tuner to prevent unauthorized usage or sharing.
  • Tune using new USB communication port or serial port.
  • New smaller enclosure for reduced physical size.
  • 1MB of internal data logging
  • Up to 12 peak and hold injector drivers.
  • Up to 8 direct-fire coil outputs.
  • Works with all AEM gauges.



AEM’s EMS-4 Universal Standalone Engine Management System is designed for use on modified Powersports and four-cylinder race car applications. With its weather/shock proof enclosure and specially designed 36-pin connector, the EMS-4 is equipped to operate in harsh environments and can be mounted anywhere.

  • 4 Saturated Injector Drivers
  • 4 Coil Triggers
  • 8 General Purpose Inputs/Outputs
  • Mag or Hall Cam and Crank Inputs
  • O2 Input
  • Knock Input
  • 8 MB Internal Data Logger
  • CAN Data Stream
  • Utilizes AEMTuner Interface Software



PC-programmable piggy-back controller that allows users to retard timing and add fuel to virtually any engine, even on variable cam timing engines (VTEC, iVTEC, VVTi, MiVEC, etc.).

  • Works with latest OBD-II (or older) race vehicles including a High-Side output based on Engine RPM.
  • Six (4-to-8) injector inputs with simulated injector load used when remapping OEM injectors Analog in / out for remapping / clamping MAF



Plug & Play piggyback Fuel and Ignition Controller (F/IC). This kit combines the power and drivability of the F/IC with a plug and play harness, start up calibration, and “quick start guide“ for fast, easy installation and simplified tuning.

  • Plugs directly into the factory harness. No rewiring necessary.
  • Includes start up calibrations.
  • Enables MAF-clamping/recalibration.
  • Runs in conjunction with factory ECU. CAN-BUS not affected.
  • One of the only piggyback systems which can decrease pulse-width, allowing larger aftermarket injectors while maintaining proper air/fuel ratios.
  • 64kb of internal data logging.



Convert your distributed ignition to coil-on-plug for more power!

  • Bolt-on Systems available for most popular V8 engines and Honda B-, D-, H-, and F-series engines
  • Very simple four-wire connection for easy installation (12V, ground, crank signal, and cam signal)



Eliminates low-response, high-impedance "saturated" injectors for high volume fuel delivery!

  • For high-output engines that have exceeded the capacity of high-impedance injectors
  • Includes 10 independent injector drive channels for any engine up to V10
  • Complete wiring system included
  • Operating Voltage: 8-18 volts, negative ground



Laboratory-grade accuracy eliminates inaccurate temperature sensor readings!

  • Uses common miniature thermocouple connectors or ANY K-Type thermocouple
  • On-board cold junction temperature compensation for laboratory-grade accuracy
  • Includes FOUR (4) 0-5v analog outputs
  • 0-1,000 C (32-1,832 F) measurement range



When you need to upgrade them, we have them in stock!

  • High-quality sealed sensor housings
  • Mating connector and 12“ leads included (sensors)
  • Accurate and affordable!


AEMnet High Speed Communication Network

AEMnet is an open architecture software and hardware interface based on the CAN 2.0 specification, which provides the ability for multiple enabled devices to easily communicate with each other through a single cable.

  • Infinity Programmable Engine Management
  • Series 2 Engine Management System
  • EMS-4 Universal Standalone Engine Management System
  • 4-Channel Wideband UEGO Controller
  • AQ-1 Data Logger
  • Wideband Failsafe


AEMdata Data Analysis Software

AEMdata data analysis software is a custom data analysis package for select AEM products that features advanced 3D graphics and a user-friendly interface. It allows the user to review and playback vehicle, driver or engine data and overlay this data using charts, dash displays, gauges, or custom displays that you create. High-speed logging is saved to a file internally or via PC connection.

  • Multi-tabbed, customizable workspace
  • Drag and drop channel selection
  • Smart data organization
  • User-defined math channels
  • Channel statistics include min/max values, start/end vales, time at start/end of range, time at sample min/max distance at start/end of range, min/max distance samples and more!
