Setup/Tuning for Active Exhaust

EMU BLACK / CLASSIC
1

I am planning an active exhaust install with EMU Black. The valves work on vacuum, e.g. the valves open when the vacuum drops a certain amount (WOT). However, I want to control the opening and closing based on RPM and not vacuum so I am looking for a way to send an output based upon the RPM of the engine. How would I configure this?

Also, does anyone have any links/reading for tuning with active exhaust for EMU? I have found a ton of snippets for this, but nothing for EMU?

Use a Parametric output? RPM as variable, gives you a few further options too.

Got it. Generally, should this be setup on a MAP signal to control open/close or RPM to control open/close or what are some other options?

World is your oyster in my opinion. Normally I like to have valves on a switch, but if overriding that I would probably use RPM vs TPS. N
