Bill,
I for one appreciate you (and Neil’s) continuing effort to develop a reliable gearbox. New rotary installs are done without this critical piece of hardware. I like Ross’s systems and dual controller philosophy as well. Each controller has an separate CAS and each controller actively fires a set of plugs. In our case A controller would fire leading and B controller would fire trailing. Injector can be fired from either controller with a selection switch like Tracy’s. If not for Tracy EC3 I would be bugging him for an alternative. The Motec M4 has the ability to program the location of the CAS. Crip Function I believe. This opens up the possibility for dual M4’s utilizing Ross’s dual controller philosophy and possibly is injector relay box. Each M4 runs about $2000 but I do see some used ones on eBay for less than $1000. – Ouch!
Keep us posted on the P-port and PSRU development.

Richard,
Ross and I specifically talked about running the rotary. I really like Ross' system and I would like to run it. In the past he had a system dedicated to the 2 rotor. It is very much like a 4 cylinder piston system. If he has stopped making it that would be a shame. I don't like the Halltech units I have seen and the alternative is the Motec which is a good system but over priced compared to the SDS.
