Now, where to put the controller? This car lost its 10 pounds of passenger airbag in a weight weenie attack over a year ago. The resulting hole is perfect for the job at hand!
Now, if this AEM 4-Channel UEGO Controller is going to be useful, we need some way to collect the data. AEM's low-cost AQ-1 data logger is a no-brainer for this task. The low-cost bit should be reason enough, but there's also seamless CAN communication between the UEGO controller and the AQ-1, the AQ-1's built-in accelerometers, and easy data analysis on AEM's new AEMdata analysis software.
Since the AQ-1 has accelerometers on board, it's important to mount it level. There are a few different acceptable orientations which should allow you enough mounting flexibility to find some good solution for your car. If it's horizontal though, we had to orient it like this, with the connector on the left.
Level mounting while clearing the dash bar that passes through the bottom of the airbag hole required these stacks of coroplast and tape. Note how the stack on the left has one extra layer of tape to make the box level.
Adhesive-backed velcro holds the UEGO controller to the AQ-1, and there's just enough free space in the airbag hole for hiding surplus wire.
Connecting the UEGO controller to the AQ-1 is as simple as plugging in this one AEMnet connector. Note the unused connector in the background, allowing you to keep daisy-chaining AEMnet compatible devices. At the moment, those devices include the EMS stand-alone engine management and Dyno-Shaft on-board dyno.
Wiring in other vital data, like RPM, coolant temp, intake air temp and throttle position is still relatively easy with AEM's idiot-proof harness labelling.
