I've often wondered what's the fastest possible telemetry response to a flameout .. you could look directly at exhaust temperature, or the RPM or the pump voltage. I've always presumed that temperature would be the best, since the RPM response would be slowed by mechanical inertia, and the pump voltage (and the ECU code for flameout) only occurs after the ECU figures out what has happened and starts to take its own action.
But I've never done any actual tests .. and perhaps the time difference is only fractions of a second and would not really matter anyway.
I do like the idea of a stick shaker.
