changing dms3 from v4 to v? ??

Yes it will work in another PS2 version if it has already been installed in a V4. It doesn’t really "calibrate its self" so to speak. Every time the console is turned on and the chip with it,…..it just uses the code it needs to work with what ever version PS2 it’s in at that moment, in affect "calibrating its self" every time its turned on. But you are also right in saying that the DMS3 that will work in your V4 will only work up to V8 consoles. The V9 and V10 would need the DMS3 V9 to work.
