Knock warning after ecutek tune

Quicksilvers

One thing that was not said here is Nissan highly recommends only using “top tier” gasoline in all of their model vehicles. It is crucial what gasoline you use with the ECUTEK and UpRev tunes for our Z’s. Also if you use generic additive low quality gasoline pinging or detonation can and will happen. People getting a ECUTEK or UpRev tune on any Z need to clarify how they want their tune done before hand.
