    So with only 125 Miles on my new Hellcat the check engine light has poped up and I have two codes thrown, You can not just pull the Exhaust Valve Fuse #36 (15) amp like people have in past on Vettes and Camaros to keep the electric cutouts open, I tried this and it kicks them open but pops codes I had to clear them out twice today so this will be an on going trial and error to find something that works. Just the heads up.

    I'm sure when the tuners cracks it in 10 years you will be able to clear the codes permanently

    Someone here has said that puttting the car in track mode opens the valves. Have you tried this?

    I have also read that but I have tried it in Track , Sport, and Custom and the valve only opens above the 1200 / 1500 RPM range it starts open when cold and when the rpms drop as engine warms they close up and the exhaust note is curbed I see they are three wire cutouts so I would assume ground power and signal to show open and closed postions I will try again this week and work with resistance to see if that is a option.

    Can you tell what type of device is driving the valves open? Do you think they are capable of more than just open and closed?

    They are just electric valves and from what I can tell they open and close fully no halfway I will be removing ehaust to see for sure what is happening there and how to control it manualy.

    Need to do this on vehicle dyno to monitor what happens at different vehicle speeds. Valves most likely will change with vehicle speed, engine load and rpm in order to pass sound level certification during different driving scenarios that are tested by certification body.

    Valves will also have a diagnostic that checks to see if motor moves and follows commands properly and that it is connected.

    LOL, Can you imagine the Dodge engineers reading this thread and shaking their heads. "Give them rednecks all the technology we can muster, and they want to thread a coat hanger into the cabin to control the exhaust sound" WTF???

    Yeah don't have a Dyno and and all I can tell is that they open up at about 1200 RPMS and when engine is under load. Hopefully someone can shed some light on this and the gains or losses if any I wouldnt mind a loss the sound makes up for it.
