AEM PERFORMANCE ELECTRONICS AQ-1 OBD-II DATA LOGGER: 1996+ OBD-II VEHICLES

AEM has released its AQ-1 OBD-II Data Logger and AQ-1 OBD-II wiring harness. With a combined street price of under $700.00 for logger and harness, it may be the ultimate data acquisition device for sportsman racers and track day enthusiasts! The AQ-1 OBD-II Data Logger reads and records data from a 2008-up vehicle’s OBD-II port using a supplied connector on the harness, providing critical engine and chassis data with minimal wiring. Just power the unit, configure the OBD-II data in the free setup software and it’s ready to start logging. It also has the ability to read, store and clear diagnostic trouble codes (DTCs) from the OBD-II port.

STORE TROUBLE CODES (DTCs) AS THEY HAPPEN
The OBD-II DTC page in the software allows viewing and clearing of DTCs, however the AQ-1 is also capable of logging (“Stored” only) DTCs as they occur. When OBD-II PID logging is enabled, DTCs will be queried from the primary/engine ECU and placed in the data log as “Markers” so you can see all of your other data at the same time the fault PID was triggered. Pending and Permanent codes will not be recorded in the data log, only Stored codes from the primary/engine ECU.

EXPANDABILITY
The AQ-1 OBD-II 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 OBD-II 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
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)
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.
