X-Series Wideband AFR Controllers, the Fastest Responding Wideband in Independent Testing.
X-Series Widebands are built upon unique, patented X-Digital technology and are the fastest responding wideband air/fuel ratio sensor controllers in independent testing.
X-Digital wideband technology is a proprietary, 100% digital technology and is what gives these sensor controllers the ability to read and report values more quickly than other widebands, which can help tuners deliver more optimized engine tuning and a safer overall operating condition. The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, so it has the ability to ‘see’ changes in AFR that other controllers may miss: changes that could mean the difference in lap times and engine longevity.

  • Patented 100% Digital Technology delivers the fastest response time
  • Includes Bosch 4.9LSU Sensor
  • Factory or Free-Air Calibrate
  • Displays values in either AFR, Lambda or O2%
  • 16V System Compatible

X-Series Gauges combine incredible looks, increased readability and a multitude of new, easy-to-use features! It is a must for users who want highly accurate oil or fuel pressure readouts in their high performance vehicle.

Visual improvements include a bright center LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping green LED “needle” lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825”, with a cup depth of only 0.200.” This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere.

Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CAN-bus enabled, so they can be daisy chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or 3rd party EMS or logger that accepts AEMnet. 0-5V analog outputs are also included for inputting into data loggers and engine management systems.

X-Series Gauges are available for popular pressures and temp monitoring, as a GPS-based Speedometer, and “Streaming” Gauges for monitoring multiple vehicle channels through the OBDII port, or AEM standalone ECU.

AEM Infinity ECU

The Infinity ECU delivers high end Motorsports capabilities powerful enough for professional teams at a price that makes it attainable for sportsman racers. Infinity systems come fully enabled without the need for feature add-on purchases. Combined with AEM’s industry leading after-purchase support system, including free technical support, the Infinity is the ultimate engine control solution for both professional race teams and weekend track cars.
The Infinity’s airflow-based tuning models simplify system installation and speed the tuning process by eliminating many of the setup requirements necessary in previous generation ECUs. By tuning the ECU based on the Volumetric Efficiency and the desired Air-Fuel Ratio for the engine, the resulting calibration values make logical sense to the user.
The Infinity ECU is built around a 200MHz, 32-bit automotive processor and Real Time Operating System (RTOS), which is capable of processing 400 million instructions per second. It is dramatically more powerful than many other current Motorsports ECUs commonly available. This allows the Infinity to do more, faster, in a more stable programming environment.

  • The Infinity’s 200MHz processor allows the ECU to fully update the model more frequently than the competition, allowing the ECU to always use the most accurate, up to date sensor data before injecting fuel or firing the ignition, allowing the Infinity to control the engine more accurately.
  • The Infinity’s speed allows for more crank trigger pulses per revolution and at higher RPMs. This allows for more accurate ignition timing, which enables an engine to create more power
  • The Infinity’s more powerful processor allows it to data log up to 100 channels, each at up to 1000 times per second simultaneously, with no impact on the model processing function or running the engine
