| The 4 bolts are tightened securing the driveshaft to the flange of the diff and this car is now mechanically ready to roll under its own power! |
As we mentioned we’re using AEM’s AQ-1 data logger to host the data output from our Dyno-Shaft. Steve Rockwood did an excellent writeup on the AQ-1 several months ago when it was installed in Project G20 Racecar, so if you haven’t read it yet go check it out HERE!
 |
| The AQ-1 makes datalogging a cinch and at less than $400 it’s a steal! We got it just for our Dyno-Shaft but when we saw how easy it was to setup we figured we’d utilize it to log engine speed, vehicle speed, throttle position and oil pressure—all pinouts on the bulkhead connector from our E-ROD’s wiring harness. |
 |
| We opted for the 96″ harness since we weren’t sure where we’d mount our AQ-1. That plug in the front is the AEMnet cable which is the only wire we need to plug our Dyno-Shaft into! |
The AQ-1 can be ordered with either an 18” or 96” harness. Each harness has 8 inputs—4 analog inputs to measure frequencies between 0-5V with optional pull-up resistors for thermistor style sensors (like a water temperature sensor), and 4 additional analog inputs to measure frequencies between 0-5V or 0-16V, the latter being useful for RPM, vehicle speed sensors or other frequency based signals. The AQ-1 also has 3 “switched to ground” digital inputs for logging brake, clutch pedal or cooling fan actuation for example. There is a built in 3-axis accelerometer and an input for a GPS signal via an RS232 serial connector so overlaying your GPS positioning within the AEM Data software could be had for the $85ish cost of the GPS antenna—a no brainer for the track day junkie!

| All wires on the AQ-1 are printed every foot or so with whichever input they are so you gotta be pretty dumb to mess it up! |
