Dual scroll actuation on N/A ECU
I know this is a long shot, but does anyone(HAILERS?) know if the N/A ecu shoots out a signal out ~2700 that I can use to actuate my dual scroll? TIA
edit: setup is s4 n/a block, all s4 t2 accesories, S4 N/A (326?) ECU

Not that I know of.
Really, don't worry about it. If there is no twin scroll solenoid and no vacuum line going to the turbo's twin scroll actuator, it will FAIL SAFE to the wide open position. That means you'll get full boost as long as you don't attach a vacuum line to it.
It will mean a slightly slower spool up. Some people say they don't really notice the slower spooling.
A fifty dollar RPM switch from SUMMITRACING can be used to switch it if you want to do that.

Yeah, that's (rpm switch) what I was thinking. Personally, I have driven without and with, and I feel there's a huge difference. Anyways, thanks for the heads up.

Aw shucks. I shoulda figured out the vacuum there/vacuum gone thing. Still, the end result is like not having a vacuum line on it.
Seems you could get a series four ECU for fifty or so plus a boost sensor to compliment it for another ???????? fifteen? Sometime in the future. Maybe EBAY or the for sale on this forum?

Yeah so far I love the driveability with the high comp rotors. I am planning to run TII ECU, just trying to find a decent price on one. OT, but Aaron I know you went FMIC from the start, one thing I don't think people realize is the TMIC sits on top of the N/A oil fill.
