I tested ezbuilder with hitec servos, and discovered ezbuilder is not able to make them move in their full rotation range, largely exceeding 180.
The full ezbuilder 0-180 range produces a rotation of about 163. And , of course, no corrispondence between the degrees set and the actual servo position.
I was told by DJ Sures, that ezbuilder was made for ezb servos, and compatibility is not guaranteed with hitec servos.
I should suggest EZ to make a software update to ezbuilder to let users configure it to their own servos. I think it shouldn't be a difficult task.
It woulde be useful to many users !
The EZB controller has 2 micro-controllers, one is used for the WIFI and the other one manages the hardware ports & speaker.
Both micro-controllers do not support over the air updates, the only solution is to use 3 party tools.
Unless there is an EZR firmware builtin functionality (not advertised until now) to specify the min and/or max servo pulses, i don't see that happening.
currently we are able to flash the WIFI micro-controller :), nothing is impossible but is not so simple.
Let's wait for DJ's answer.
DJ made me see an oscilloscope skecth, showing the pulse range of ezbv3, that was wider than ezbv4 I have. They changed, mantaining compatibility with EZ servos, but not with hitec's.
You could try using a servo stretcher like this:

But it will effectively add $20 to the cost of each servo.
I have no idea how @DJ set his servo mins and max for ARC and/or firmware, but if it were me doing this I would hard code for a buffer at each extreme to help protect servos from accidently hitting their stops...
Yes, I might use servo stretchers or other controllers.
EZB has greatly reduced my hardware .It does everything !
Unfortunately I'll have to increase my hardware again.
Adding the ssc-32 is only 2 wires - and will free up many digital ports on the ezb for other features... Such as leds or switches , etc
