As the title suggests I have a busy project. A single Racepak SmartWire does not have enough outputs for my crazy plan.

Has anyone chained this many items together before? I assume that it can be done and that I don't need to have multiple laptop connections for program changes?

What is the best way to connect them together? I'm thinking that there are not enough connections and they I will need to add something else? Do I need a module of some kind?

I also intend to connect it to my GM crate engine and pickup as much data as I can such as temps and pressures for my IQ3.
