Flames out exhaust rev-down from 6,000 RPM

Yup, also check your injectors.

My friend had the same issue. Fixed it by changing the tune-up with the computer.

Squential injector timing, lead and split ignition are good rotary specific things to cover. Might want to hit on MAP sources too. The rotary has strong pulses compaired to pistion engines and you can get a fair amount of shock, so picking your MAP source vac line can be critical for good signals to the barameter sensor. All other parameters are pretty generic to most internal combustion engines like air temp, coolent temp and throttle positions.
