The one I installed recently has the revv limiter built in. I like that feature!

I tried one. It made my tachometer needle bounce around. I only installed it because it had a rev limiter.
I have Dakota Digital gauges. Apparently, these two don't co-exist well. I even put a diode in the negative coil wire and it didn't help.
