From your link...
4 Spark Outputs (Up to 4 Cylinder Coil On Plug, up to 8 Cylinder Wasted Spark)

Natively support two fuel outputs for batch or bank-to-bank fueling. Optionally upgrade to 4cyl sequential or 6/8 cyl semi-sequential with this module.

The way I read this is that even with the upgrades, you don't get CoP for 8 cylinders, and only 'semi-sequential' fueling for 8 cylinders

I apologize after rereading the link you are correct, I believe you have to build an ms pro for that application.
