I'm not sure if the "MZ" telemetry programming is different than the "SZ", so crosscheck your RPM between the GSU and your transmitter to verify they're saying the same thing.

P.S. Looking at your setup, I don't think you need the ECU PPM to Rx Ch3 cable for throttle. I run mine from ECU Telemetry to Rx SBus2 only for throttle...just ensure the GSU/ECU throttle setting is set for Ch3. Maybe the tech experts here can comment if the way you have it establishes throttle redundancy.
Sean - an interesting observation that I hope the tech experts will chime in on. I use Futaba in all of my planes. It is my understanding that the SBUS2 connection is to be used only for telemetry connections and not for throttle or servos. It is my understanding that throttle and servo connections are only made via the SBUS (not SBUS2) or directly to channel connections on the receiver. Can anyone tell us what is true?
