The AQ-1 OBDII Data Logger includes an onboard 3-axis accelerometer and is expandable through eight supplied analog inputs, three switched digital inputs, AEMnet CAN bus, and an RS232 serial connection. These allow you to add specific channels that may not be present on the OBDII datastream including:
  • Four 0-5V analog inputs with software selectable 2.2k pull-up resistor for thermistor (temp) sensors. 0-5v examples: AFR, Boost, Boost before/after the intercooler, MAP, Exhaust Backpressure, Crankcase Pressure, Fuel Pressure, Oil Pressure, Clutch Pressure, Brake Pressure, Shock Travel. Thermistor examples: Air Temp, Coolant Temp, EGT, Trans Temp
  • Four 0-5V/0-16.5V analog or Frequency inputs for all of the above plus RPM, Driveshaft Speed, Wheel Speed and Turbo Speed
  • Three switched digital inputs for Clutch Switch, Line Lock, Nitrous Switch, Line Lock, etc.
  • RS232 Serial connection for GPS, older AEM engine management systems that transmit data through serial, etc.
  • AEMnet CAN bus for daisy chaining X-Series Wideband Controllers and performance gauges, 4-Channel Wideband AFR Controller and Wideband Failsafe gauges, Vehicle Dynamics Module to add GPS and gyroscope, or Infinity ECU, Series 2 or EMS-4 EMS systems (future upgrade path)

AEM’s AQ-1 Setup Software is intuitive and easy to use. Configuring the OBDII data is as simple as connecting permanent power, switched power and ground, connecting the OBDII plug and connecting the AQ-1 OBDII Data Logger to the vehicle. On average 20-40 channels of data are transmitted. Simply select the channels you wish to log from the data stream, set the logging rate, name the channels if they are not already named and it is ready to go.

The setup screen is broken into a Navigation Tree for your available input channels, Device Info area for data rate and available memory, a Status Bar and a Center Pane to enable and name available logging channels. Setting logging conditions, channel options, calibration data, lap beacons, reading battery voltage, configuring the accelerometer and serial input and more are found in easily navigable subpages.

The inclusion of an AEMnet CANbus input allows for the addition of multiple channels from AEMnet equipped devices through a simple one plug connection. Adding GPS for track mapping with a Vehicle Dynamics Module (VDM), wideband AFR, pressure or temp data from X-Series Digital Performance Gauges, individual cylinder AFR from 4-Channel Wideband Controllers, engine data from an Infinity ECU or Series 2/EMS-4 Programmable Engine Management System and more is all possible without the need to wire additional inputs into the unit.

AEMdata analysis software features advanced 3D graphics and a user-friendly interface. It allows users to review and playback vehicle, driver or engine data and overlay this data using charts, dash displays, gauges, or custom displays that you create, or you can select pre-defined templates. All channels are listed in the AEMdata set up menu. Users simply drag and drop the channel that they want to analyze into the window and it will display. 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. Track mapping is achieved through GPS or a combination of vehicle speed and accelerometer data, and adding data overlays to HD video is possible using the software’s powerful video encoding feature.

  • Four 0-5 V analog inputs with optional pullup resistor for RTD/Thermistor-style sensor
  • Three switched digital inputs, 16.5 V MAX
  • AEMnet connection included for easy connection to AEMnet enabled devices
  • RS-232 serial input included for adding NMEA0183 GPS device
  • Internal 3-axis accelerometer (+/- 4g MAX)
  • Logging rates of up to 1000 samples/second per channel
  • 8GB removable SD card included for log files (Up to 32GB compatible)
  • Compact size (4.8" x 4.55" x 1.44") and weather resistant when included protective outer boot is used
  • Track mapping capability

  • Free AEMdata analysis software with HD video encoding for adding data overlays to videos

Proposition 65

/!\ warningWARNING: Cancer and Reproductive Harm

When racers and enthusiasts buy AEM performance parts, they are getting the finest engineering, highest quality and best value our industry has to offer. Look no further than our products for proof. AEM created the first stand-alone programmable engine management system that uses a factory wiring harness, and was the first to introduce a gauge with a built-in wideband UEGO controller and gauge readout in one unit! More recent innovations include our Water/Methanol Injection Systems, which provide the ultimate combination of performance, quality and value for gas and diesel race vehicles, a complete line of digital and analog display gauges, and the X-WiFi module, which allows users to view critical exhaust data wirelessly on virtually any WiFi enabled device. In addition, the recent release of AEM’s Series 2 EMS with AEMTuner interface software represents a major evolution in features and ease of use from the original.
