AEM AQ-1 OBD2 Data Logging System

Overview

In addition to reading data from a vehicle's OBDII port, the AQ-1 OBDII Data Logger includes 8 analog input channels, 3 switched digital inputs, a serial port for GPS, an on-board 3-axis accelerometer and AEMnet CAN bus cable for daisy-chaining AEMnet equipped devices into the logger and storing all data in one file!

Features

EXPANDABILITY

The AQ-1 OBDII Data Logger includes an on-board 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 pullup resistor for thermistor (temp) sensors. 0-5v examples: AFR, Boost, Boost before/after 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 gyrometer, or Infinity ECU, Series 2 or EMS-4 EMS systems (future upgrade path)

EASY SET UP

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 data channels are transmitted. Simply select the channels you wish to log from the datastream, 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.

FREE AEMdata ANALYSIS SOFTWARE

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.
