NEW FOR 2016! X-Series Wideband AFR Controllers, the Fastest Responding Wideband in Independent Testing 
X-Series Widebands are built upon unique, patent-pending X-Digital technology and were the fastest responding wideband air/fuel ratio sensor controllers in independent tests against 17 major wideband air/fuel competitors.

X-Digital wideband technology gives these sensor controllers the ability to read and report values more quickly than other widebands, which can help provide 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, making it able to identify the slightest fluctuations in AFR and output them in full value.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s X-Series Wideband Sensor Controllers can reduce deadtime so you can improve the performance of a vehicle through more accurate AFR tuning. Please visit www.aemelectronics.com for more information about response time.

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

AEM Water/Methanol Injection Systems (WMI) deliver more features per dollar than any other WMI system available. The Controller Modules for its WMI Injection Systems are easy to program, and added kit enhancements like “Boost Safe,” color-coded wiring with a positive-lock connector, heavy-duty high-pressure injection pump, machined billet nozzles and a conductive low fluid level sensor improve system performance and simplify installation. AEM WMI kits work on high-compression naturally aspirated and forced induction gas or Diesel race engines!

AEM offers two different water/methanol controller designs: a Boost Dependent controller (up to 35 PSI) with an on-board manifold absolute pressure (MAP) sensor, and a Multi Input controller that works with an external MAP sensor, frequency based Injector Duty Cycle (IDC) input, frequency-based mass airflow (MAF), or voltage-based MAF.

AEM Water/Meth Controller Features (PN 30-3300 Boost Dependent - PN 30-3350 Multi-Input)

  • Robust controller designs are easy to install and program
  • Simplified wiring harness
  • Integrated “Boost Safe” feature
  • Heavy-duty high pressure injection pump
  • Low profile tanks with conductive low-fluid level sensors
  • Machined billet injectors and nozzles

More Water/Meth Injection Info

AEM offers a variety of in-tank fuel pumps and a 380lph inline fuel pump in the popular “044 style” dimensions that can support 860 HP at 30 PSI of boost! 

AEM’s E85 Fuel Pumps (indicated by the green tops) feature robust internal construction that are designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and have been tested to work with ethanol fuels up to E100, methanol fuels up to M100 and all types of gasoline. Flow curves from 35-90 PSI and current draw vs. pressure charts are available on the company’s website. 

AEMdata data analysis software is a free custom data analysis package for AEM products that features advanced 3D graphics, HD Video support for virtually any type of camera, and a user-friendly interface. High-speed logging is saved to a file internally or via PC connection.

CREATE AND SHARE HD VIDEO WITH DATA OVERLAYS! AEMdata allows you to combine vehicle data and HD video to review and playback vehicle using charts, dash displays, gauges, or custom displays that you create.

All channels are listed in the AEMdata set up menu. Simply drag and drop the channel that you want to analyze into a lane or gauge and it will display. Users can set alarms and program definable color changes for parameters of logged channels to quickly skim logged data for color changing peaks and valleys, versus tracing the channel log to find where the problem occurred. AEMdata has powerful features including custom math channels, x/y plots and histograms, stage or circuit modes and more, all aimed at making sure you get the most out of your data.
