I'm planning on a pair or maybe even 3 MS3 units with a relay board going between them. Basically, said board would distribute any and all sensor signals so that all MS3s would see all the signals, but the injectors and coils would be run by only one MS3. I don't yet know exactly what I'm going to do here, but the MS3 (with the expansion board) can run 8 injectors. I'm thinking 2 or 3 per rotor, so that if any one injector goes down, it keeps running OK. The MS3 does the whole injector staging thing well, so that might work. It also has 8 sparkplug outputs (with the expansion board), so it can drive each independently.
