The hardware comes as pictured, brand new and including the basic set of cables needed to read from most vehicles. In addition to the hardware, you will need to purchase protocols, listed in Ktag Software; or alternatively you can purchase the Ktag Starter Kit. You do not need to purchase subscriptions as the first twelve months are included in any protocol package.
KTag is an ECU out (removing ECU from vehicle) tool and whenever possible, Kess should be used instead, particularly as extra labor time is required for K tag. If someone was to own only one of these two tuning tools, it should definitely be the Kess.
