Installation

Mounting

The AQ-1 is provided with a sealed main connect or and EnviroSeal boot to cover the integrated USB port and SD card slot. Nevertheless, c are should be taken to located the logger in a relatively cl ean, dry envi ronment as it is not completely water-proof. The provided hardware and mounting template (included in this manual) may be used to mount the unit; alternatively , hook and loop fast ener (not provided) may be used. It is ac c eptable to pierce the EnviroSeal boot t o accommodate mounting hardware.

For the internal acc elerometer to work properly, the AQ-1 must be mounted such t hat its largest surface (top or bott om) is either coincident with, or at a right angle to one of the primary axes of the vehic le. Please reference t he acc elerometer calibration sect ion of this manual and/or the configuration s oftware for more detail and images of acceptable orientations.

Electrical Wiring I nstallation

A wiring harness is not included with the 30-2500 kit, however the purchase and use of the AEM 30-2906-96 AQ-1 Data Logg er Harne ss is highly recommended. This harness has been designed to ensure easy ins tallation, si gnal integrity, and proper logger operation. Only skilled, experienced installers s hould attempt t o s ource and design their own harness. The connector part numbers (AEM does not s upply t hes e parts separately outside the 30-2906-96 or 30-2907-96) are provi ded below for this purpose.

Impo rta nt Wirin g Tips

· Permanen t 12V (Pin 6) must be connect ed t o a cons t ant 12V batt ery source that is not disconnected via a cut-off switc h or sim il ar.

· Switc hed/Ignition 12V (Pin1) must be c onnected to a swit ched ignition s ource that energizes when the vehicle is i n use and is off when the vehicle is not i n use.

· Frequency i nputs (Pins 12-15) must only be connected to c l ean DC square wave signals. Connections t o igniti on coils or magnetic/VR sensors will damage the logger.

· CAN wiring (Pins 27-28, 33-34) must utilize twist ed pairs with greater than one twist per inch.

· USB wiring (Pins 31-32, 35-36) is only required if users wish to mount a USB port remotely; t he integrated USB port

funct ions ex ac t ly the same. USB wiring requires special care; please contact t he USB consortium (usb.org) for proper wiring conventions.

· Proper crimping, s hielding, and harness routing practices should always be implemented.

W i ring: A nalog Input 1 - 4

This class of inputs is suitable for logging the output from a variety of sensors which have a continuously variable (analog) output between 0 and 5 Volts. A software selectable 2.2kOhm pull-up resistor is available.

Typical Automotive 0-5V Analog Sensors

The majority of these sensors are either "two wire" or "t hree wire" t y pe s ensors. Typically , these s ensors will have a 1) signal ground wire, 2) si gnal wire, and sometimes 3) power (5V) wire. W i ring the sensor into the analog input of the AQ-1 logger is a m att er of connecting one of the logger's analog inputs t o t he "signal" wire of the sensor. Please refer to the documentation that came with y our sensor, gauge, or the factory service m anual for your vehicl e to loc at e and identify the appropriate signal wire.

Software S electabl e 2.2kOhm P ul l -Up Resistor

Analog inputs 1-4 are the only A Q-1 inputs t hat are equipped with a pull-up resist or. P ull-up resist ors are required when using two wire sensors (RTD, t hermistor, temperature sensors, e.g. ECT, EOT, AIT) that ARE NOT already wired to a second data sy stem or ECU.

Yes, you need a pull-up resis t or when

You want a log a pre-existing AIT sensor that's already wired to your engine management sy stem or ECU.

No, you don't need a pull-up resist or when

You want to log an AIT sensor that you purchased from a third party, l ike AEM, and installed in y our intake and is not connected to any other ECU, EMS, logger.

W i ring: A nalog / Frequency Input 4 - 8

This class of inputs is suitable for logging the output from a variety of sensors which have a continuously variable (analog) output or, optionally a DC frequency, between 0 and up to 16 Volts. These i nputs do not have any pull-ups available.

Typical Automotive 0-5V Analog Sensors

No Pull -Up Resistor Avai l able

Analog inputs 4-8 do not have any pull-up resistor available. Two wire sensors m ay only be c onnected to t his i nput if they are connect ed to another data sys t em or ECU within which there is a pull-up resistor.

The use of a tac h adapter such as t he MSD “Tach S ignal GMR Pic kup” Part Number #8918 is usually required when attempting to log engine rpm from high-voltage noisy sources.

Inject or Duty Cycle / B oos t Control Solenoid

Solenoids are typically t wo wire devices where 1) one wire is c onnected to batt ery voltage and the 2) sec ond wire is connected to a low-side output of an ECU or controller -- wire 2) should be connected to this input for the purposes of logging.

W i ring: Digital Input 1 - 3

This class of inputs is suitable for logging the output from "switc hed to ground" digital signals with a maximum voltage of 16V.

Typical Automotive Digital Signals

Solenoids are typically t wo wire devices where 1) one wire is c onnected to batt ery voltage and the 2) sec ond wire is connected to a low-side output of an ECU or controller or ground -- wire 2) should be connected to t his input for the purposes of logging.

A s t art/ s top switch t ypically has t wo terminals where 1) is t o be connected to t he logger and 2) is connected to ground. Important Note: These inputs are not int ended for use with solenoids or signal sources that are pulsed with a (high)

frequency for the purposes of control or feedback.
