Tricky,
Does this tool allow you to read live error codes while you're driving the vehicle? And does it definately work with all JDM 350z's?
Which package deal did you get?
I haven't actually checked to see if it displays codes while driving, but as its a live process i can't see why not, as for it working with the 350Z you should be able to check on the Blazt site, but i see no reason why not as its designed to work with all OBD11 Nissans.
i bought mine from a UK ebay seller who is the official Blazt UK retailer,and it also works out cheaper from him as i checked with the NZ guys on shipping etc, but i think he has no cables left at the moment, as all i could find was this,http://cgi.ebay.co.uk/BlaZt-ECU-Cable-4-Nissan-Micra-Primera-Almera-200SX-/290434190999?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item439f3a0e97
You can always send him a message and ask when he will have more.
