Here's an example that shows the expandability of the CD-7 using AEMnet to communicate with other AEMnet devices which is especially useful if you're running a reflashed OEM ECU or other tuners. As we all know, it's imperative to maintain acceptable air fuel ratios - especially if running forced induction. The RZR motors have an incredible power output capacity and are run very hard out on the trail or in the desert or in dunes or where ever and it's important to ensure that AFRs are in check. Getting AFR data displayed to the driver is as easy as installing an AEM X-Series Inline Wideband UEGO Controller. The inline wideband UEGO is just like it sounds. Instead of having a gauge that's mounted in the cockpit, the UEGO control module is "inline" between the O2 sensor and it's output which in this case is the AEMnet CANbus data stream. Besides power and ground, getting AFR to read on the CD-7 means connecting the two CAN wires and adding an AFR channel to your layout. This way you can keep an eye on your air fuel ratios but you can take it step further. The CD-7 has user configurable alarms with many levels of trigger logic that make it easy to make a very useful alarm that doesn't mistrigger and come on when you don't want it to. You could use the existing alarm page in the RZR layout and add the trigger criteria to be when AFR is leaner than 13.5:1 and when engine speed is greater than say 3000 rpm and when there's a least some positive manifold pressure. This way, if you're out romping in your machine and can't actively keep an eye on your AFR because you've got to keep on eye on where you're driving, you can have this big alarm jump up, grab your attention and say "Whoa, AFR's have gone lean!". Or you could dial it down and turn on either the amber or red LED. Again, everything is fully configurable but you can see how powerful the CD-7 can be - especially when you start pairing it with other AEMnet devices.
