some sort of rev limiter. i have never been good with tuning or anything along those lines. but what is that?

 

The AEM EMS is capable of a 2 step rev limiter. One will let you hold a lower rev limit when you are sitting still. This helps with launching. So with an s2k you could set the first step at 6k rpm...push on the accelerator till you get to the rev limiter and then drop the clutch.

 

wow, that's a horrible spot for a headunit.
