Regarding ECU test needing parameters in the green: I've got this logged and will look into this.
Regarding the two cycles, this is currently simulated already, what parameter is making you think it isn't doing the two cycles?
Regarding ECU switching, this is also already simulated, there should be an RPM kick when the handoff occurs.
Regarding speed bugs, the V speed notes are unfortunately not something we can change much as it is part of the X-Plane X1000 and only certain values can be set.
