Hey I have a HKS vpro gold with an additional 350z harness im not using s d wss possibly gonna sell to a find a friend who has an older vpro he used on his 240sx however will it work with the older vpro silver edition on our cars??? Secondly will tuning be an issue or is it assumed that once a pro dealer like Forged Performance, GTM can tune the vpro gold their software will automatically be able to tune the older silver version of the vpro on our cars???!

 

My understanding is it needs to be v3.24 and above. ie Gold Box
