I just got my Xcal 3, and I love it, noticed a good improvement with just the stock tune, custom one has to wait for my headers to arrive. The tuner has a few options that you can adjust and I was wondering about a couple of them.

One was the Rev limiter, has a idle drive and idle neutral setting, whats the diffrence between the two?

The other is the spark plugs, has 3 options for diffrent temp, I didnt mess with it nor do I really plan to, I was just wondering what it does.
