Spartan 3 on the CAN bus

I am developing a 4-cylinder engine that will be controlled by MS3Pro Ultimate. I’d like to use one O2 sensor per cylinder. If I have 4 Spartan 3-controlled O2 sensors, can their signal be fed to MS3Pro through the CAN bus without any additional hardware?

With Spartan3 advantages would I notice using the LSU4.9 vs LSU ADV?

Thanks for any suggestions!
