EXUP Valve opening adjustment
Hey guys, first time posting.
I have a 2009 Daytona 675, M4 Slip on exhaust, 20596 Tune installed (TuneEcu), Intake flapper set to stay open below idle rpm. (Thought I'd throw this in for the hell of it)
Correct me if I'm wrong, the exhaust valve completely opens at around 4500rpm? I'm looking to be able to lower rpm when the exhaust valve completely opens.
Just curious if it's possible through TuneEcu (I didn't get a good look at the software before returning the OBDII Cable)
Not looking to delete or disable the exup valve either btw.
