I have a 1994 Nissan D21 Hardbody.
Does this software work on it? There is the DataScan I and DataScan I Dash, then DataScan II.
Also, FYI, it took me about 10 different guesses and an internet search before I was able to learn what the fastest Nissan was to finish my registration.
Perhaps they can pick an easier question to answer (like what is 5 + 2?).
