Fueltech ECU is the direction I have gone,  Neil.

I have, in fact, had a well running aircraft rotary engine with a MegaSquirt, and may again in the not to distant future.

Bobby, for a secondary CAS, wire up a Ford EDIS-4 ignition controller to the trailing plugs.  You don't even have to provide it with a control input.  It's limp-home mode is 10 degrees of advance. Set the CAS to have 15 degrees, and your set.

Gents,  There is no doubt as I continually say that tracy's gear and
indeed tracy was 20 years ahead of his time.  Being computer illiterate
I rely on others to present something like an ECU in a ready to go
format.  For that reason I have invested in the Fueltech ECU, but yet to
wire in.  IS there any on this forum that has already done this? Neil.

The current firmware and feature set supports 4 rotor, 3 rotor, older 2 rotor and Renesis engines. For the Renesis using the stock trigger wheel, a secondary CAS for a second ECU can be positioned up to 20 degrees offset from the stock location. This is a current firmware limitation. Using a rotary compatible MegaSquirt wheel, each CAS position is fully programmable. They don't support an overall "Fuel Map Trim" feature using an external potentiometer. However they have a "Fuel Table Blending" feature that should accomplish the same thing. The MS3 supports two independent Fuel Tables and you can use an external potentiometer to adjust a bending of the tables. A balance would need to be achieved  allowing either controller to provide full rich fuel as well as lean cruise. My range would be 12.5:1 to 15.8:1. May be doable.
