yep~u can use the tunning card in HK as well
I can use the tunning card which opened in Calgary when I stayed in HK in the August,2006
but the card cannot be used in the Japanese Verson machine
it can absolutely work on the English machine
English Verson is majority instead of Japanese in HK
on the other hand,it just updating the datas of your car by the card renewal
so your data won't be changed and lost by renewing the card
