I'm about 90% sure that those ECU's required you to change the trigger wheel out of the CAS to a more simple design. Nissan's trigger pattern was complicated and hard to set up in most ECU's, so AEM ended up having a more typical trigger pattern wheel made.

I'm pretty sure it's PN 30-8760, but I would pull your CAS apart and make sure it's a 50mm OD and has a "D" center hole pattern.
While AEM sort of made a Series 2 for the CA, it was basically a generic ECU and wasn't all that PnP. What you have should be AEM PN 30-6620 (Unless it's older, it could also be PN's 30-1620, 30-1621, 30-1622). If you upload the correct calibration file, and do the setup properly, it should be a good starting point. But I don't think there's an actual tuned for a CA basemap available, unless someone made one and then was willing to share it.
Also keep in mind that if this is an 8 port head and you want the power valves to work properly, there's going to be some more setup there, as I'm not sure AEM had that ready to work out of the box.
