About AEM  Electronics




Just like you, the staff at AEM races. They buy and install parts too, and they don’t like to compromise. So, if they identify a unique product idea that delivers a real solution or figure out a way to make something work better and cost less, they make it. 

AEM’s passion for making products that are considered unattainable for most racers attainable for the racing masses is evident in everything they design and manufacture. Whether you race on four wheels or two, at the track or in the dirt, sand, salt, snow or water, helping you go faster, set records and win inspires AEM to create its products.


Racers who buy AEM performance electronics are getting the finest engineering, highest quality and best value our industry has to offer. We develop our products to solve problems racers experience at the track, and make technology that was previously attainable only to high end racing programs attainable for the racing masses. Look no further than our products for proof. From our engine management systems and wideband air/fuel controllers to our ignition components, data loggers and water/methanol systems, our products deliver innovative solutions at the best prices in the industry. Visit our website and see for yourself why AEM electronics are Engineered to Outperform.

Featured AEM Electronics Products


AEM Infinity ECU

The Infinity ECU delivers state-of-the-art electronic fuel injection (EFI) control capabilities typically found only at upper echelons of Motorsports. Through the Infinity ECU, AEM makes this technology affordable for both professional race teams and amateur racers. Infinity EMS systems are available for vehicles up to 12 cylinders.
Late model vehicle ECU’s all run on faster processors. The Infinity ECU is built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), which is capable of processing 400 MIPS (millions of instructions per second). By comparison, common competitive systems typically use 20MHz to 50MHz processors. To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This allows the Infinity to do more, faster, in a more stable programming environment.

  • The Infinity’s 200MHz processor and RTOS makes the Infinity more responsive, for a better driving experience 
  • The Infinity’s 200MHz processor and RTOS allows for more accurate ignition timing, which enables an engine to create more power 
  • The Infinity’s faster processor allows it to perform more computational features with no sacrifice in processing performance 
  • The Infinity’s RTOS ensures strategic processing with optimized load balancing. This means that tuning one feature will not affect the performance of another feature

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

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. 


AEM pioneered the wideband UEGO AFR gauge in 2001, and proudly offers a complete line of wideband AFR monitoring and control solutions. AEM 52mm Wideband Gauges feature interchangeable faceplates with AFR or Lambda and interchangeable bezels, AEM’s UEGO AFR are accurate to 0.1 AFR and NEVER require free-air calibration.

  • 30-4110 WIDEBAND UEGO GAUGE, a new version of the original wideband gauge with Bosch 4.9 LSU UEGO sensor and 0-5v output for logging or feedback control with programmable EFI (outputs gasoline, methanol, ethanol & Lambda values)
  • WIDEBAND FAILSAFE GAUGE, displays AFR and boost or vacuum, can be programmed to save your engine if it runs lean, includes AEMnet (CAN bus) output for logging and feedback control, and logs AFR, Boost/Vacuum and RPM
  • 4-CHANNEL WIDEBAND UEGO CONTROLLER, delivers individual cylinder AFR values for optimum tuning, maximum performance & engine reliability, can be installed pre turbo with optional backpressure compensation kit, and includes serial and AEMnet (CAN bus) output(s) for data logging and feedback control
  • X-WIFI UEGO CONTROLLER/EGT MONITOR, Single channel UEGO with 2 EGT channels, effortless connection to iPhone or iPod eliminating need for additional gauge, and includes 0-5v outputs for each channel
