I’ve just flash my 40125S into a 48125W without any problem,i’ve just erase the rom before upgrading and so now my computer detect him as a 48125W.

2 point :

S=Z-CAV CAV technology
W=P-CAV technology

S=No Mt Rainer support for the moment
W=Mt Rainer support.

Thats all have fun.

LTR-32125W and LTR-40125W do not have mt.rainier support yet…so there goes your W theory :stuck_out_tongue:

S is Zone-CLV and W is P-CAV or CAV, you’re right about that.
