Analog/Frequency 5-8 are analog inputs for that can optionally measure frequency (0-
5 V or 0-16 V) Examples: RPM, vehicle speed, frequency based MAF, injector duty
cycle, boost control solenoid, flow sensor, hall sensor, any 3 wire pressure sensor. See
“Using the AQ1 Data Logger” for more information on configuring Inputs 5-8. The
corresponding wires in the harness for Analog/Frequency 5-8 are Yellow and are
labeled INPUT 5, INPUT 6, INPUT 7, and INPUT 8.
Connection diagrams are shown below for some of the more common sensors/signals
to be used with Inputs 1-4 and Inputs 5-8. See Figure 1.
Figure 2 below shows the connection for an engine speed signal using an AEM Twin
Fire CDI.
Digital 1-3 are switched to ground digital inputs, 16.5 V MAX tolerance.
Examples: Clutch/brake/cooling fan ground switch, nitrous solenoid ground or ground
