Thanks for the tip on timing. The RX-8 engine has a fixed crank angle sensor and indexed rotating plate on the crankshaft so I can't change the timing mechanically. Tracy's controller allows some timing changes. I'm waiting on Tracy to return home to discuss the possibility I need to change the injector flow rates. I don't know if he shipped my unit with the 13 B injector flow settings or the Renesis injector flow rates. Possibly another clue - the EM-2 is connected to the EC-2 and shows RPM, manifold and oil pressure. The RPM alternates from the correct value to NOP about 1 time/second! The manifold pressure reads 29.9 all the time!! The oil pressure agrees with a mechanical gauge.

Dennis, welcome to the NOP zone :). Looks like your EM2 and the EC2 do not fully communicate. Check all your pins. All it takes one that does not make good contact or maybe bad ground.
If your MAP reads 29.9 all the time (been there couple of times) your engine will run rich and foul plugs. The EC2 sees high MP and supplies fuel accordingly.
Check all your MP hose connections and make sure you are plugged in the right sensor. I had mine slipped out, but looked perfectly OK untill I touched it. Next time i had hose split going over the hose fitting. Get a vacuum testing pump and do leak down test. It should hold vacuum, or you can use mouth to hose test and watch if the MP changes on the EM.
Good Luck :)
