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.

And one important thing to point out is that the CD-7 is not limited to only working with other AEMnet CAN devices. The CD-7 has two CAN inputs. We typically reserve the first one for AEMnet but the second one is fully user configurable to receive ANY CAN data stream from ANY other device. It's just a matter of having the "decoding" info to take the raw CAN signal and make it read out in numbers we can understand.

You can see a list of 3rd party applications we've provided decoding info for HERE. That list is constantly growing and you'll see that the CD-7 works with a lot of different engine management systems and other UEGO controllers and analog input expanders.

The CD-7 is just a CAN receive display and logger. It doesn't have any output drivers nor any kind of boost control functionality. There wouldn't be much need for a Tru-Boost EBC if you already have an Infinity on your car. The Tru-Boost is a very basic boost controller but the Infinity has some very advanced boost control functions and can drive a boost control solenoid directly.

Just wanted to put this out there... If you have a XP 900 and happen to be using our Infinity EMS, you can re-route the fuel level signal from the stock dash to the Infinity and then transmit fuel level over the AEMnet CAN bus to display it on the CD-7 dash. We just had a customer do this and it works great.

Ah, the big question - will it work on something besides a RZR? The very short answer to that question is yes - technically the CD-7 will work on anything with a CAN datastream so long as you know how to decode it. That's what we've done with the RZR CD-7 app - we built a ready to run dash setup that's already configured to drop onto a RZR and start displaying data right away.

So can this current RZR specific CD-7 app work on a Maverick or YXZ? Well, the answer is maybe yes. The RZR datastream is largely based on a standardized CAN messaging protocol called SAE J1939. Think of J1939 as being the "OBDII" of offroad vehicles (in fact, actual OBDII is SAE J1979 - a different but similar protocol). It's very likely that nearly all late model fuel injected offroad vehicles utilize J1939 CAN communication to some extent. This means that if you took the RZR CD-7 setup and installed it on a Maverick or YXZ, you could potentially get some data to display.

But we really wouldn't want someone to invest in a CD-7 and have the chance of being able to only maybe see some data. So, we're planning on making plug and play CD-7 apps for both Maverick and YXZ vehicles. We're in a bit of a time crunch right now getting ready to release some new and exciting products at the SEMA show coming up in a couple weeks but once that dies down, we'll be looking for donor development vehicles in order to start working on these other app specific setups. If anyone reading this is interested in maybe helping us out with this, please let me know.

Ok keep us posted. I used to race a Dodge truck that was sponsored by AEM and our stuff worked great. I have an x3 and would be interested in a replacement for the stock gauge cluster that is a little easier to read, especially at high speed in Baja.
