Ed, does your XFI have an internal datalogger? If so can you view parameters such as rev limit signal voltage? My system indicates a certain voltage ....3.2 volts = rev limiter on 0 volts = rev limit off. May be a way of seeing if in fact it's being requested to be on. Also may have to set sample rate very high.... fast as comm will allow. Just a thought. Joe
