Then it has to be the timer programming -- If the motor is capable of reaching greater RPM when commanded and the ESC is capable of producing greater RPM than commanded, the only thing left is the timer. It produces greater than 9200 RPM while it is being programmed but not while it is operating in Run mode. So your changes are not being saved or it's program is corrupted.
I agree ...and guess what? My buddy Dave, who ordered and installed the same ECS/Timer combo at the same time, has volunteered his KR2 to help trouble-shoot. He has slowly raised his RPM successfully and has been flying at 9400 RPM (different motor and 3S battery though). I'll get to test his timer on Friday.
I don't have the instructions handy, but is the LED supposed to flash twice after you change the RPM to signify that the change has been saved? If so, be sure that you wait for that signal before you move on to other changes or unplug anything.
It's 1 PRESS and RELEASE of to get into program mode - LED will glow.
Then 2 presses to get to RPM setting - Acknowledged by 2 LED flashes followed by engine start up.
Then press < or > to move RPM up and down.
Then disconnect battery when RPM is where you want it.
Might as well continue ....
Note you always PRESS and RELEASE S1 button once to get into program mode - LED will glow.
Then
3 PRESSES to get to Flight Time setting, then count the 3 acknowledgement Flashes, then PRESS/HOLD S1 and count LED flashes (1 Flash = 10 seconds) and RELEASE one flash before target (not in instructions), Wait 3 sec (not in instructions - just do it), then disconnect battery.
--or--
4 PRESSES to get to Start Delay, then count the 4 acknowledgement Flashes - then PRESS/HOLD S1 and count LED flashes (1 Flash = 1 second) and RELEASE S1 one flash before target (not in instructions), Wait 3 sec (not in instructions - just do it), then disconnect battery.
--or--
5 PRESSES to get to Governor Gain, then count the 5 acknowledgement Flashes - then PRESS/HOLD S1 and count LED flashes (each Flash adds 1 to Gain setting - range is 1 through 7) and RELEASE S1 one flash before target (not in instructions), Wait 3 sec (not in instructions - just do it), then disconnect battery. THIS FUNCTION IS WHAT MADE ME PICK THIS TIMER. I'll play with it once everything else is working.

Again, I'll test a different KR2 on Friday.
If no change, I'll attempt to talk Dave out of his ECS (in a Nobler by the way).
Wish me luck,
Doug
P.S. I really appreciate everybody's help. The C/L industry reminds me of a comment made by a fellow musician friend Chris. Chris (Guitar Player) says "I'm jealous of you Drummers! Everywhere we go you guys hang out like brothers even if you haven't met, and are always helping each other be the best you can be ...very cool". Thanks again guys!
...stay tuned
