Anyone have 17 zl1 auto c304 module stock read they can share.

[JANNETTYRACING]

I have a car with the active exhaust not working and want to be sure the c304 module has not been tuned so i need a compare file.

Thanks in advance.

Do you still need this?

[JANNETTYRACING]

Yes sir thanks

I have a read on it and looking it over I suspect it might have been tampered with all set to not reported.

I don't have a ZL1 CCM handy but here is the same DTC config from a 2017 Z06 that I can guarantee is the stock tuning.

Auto or Manual?

What about these settings

I don't if this matters but this is from a manual Z06. Mode 0 is Tour mode for the Corvettes, Mode 1 is Sport, mode 2 is Track. On the Corvettes you can do a quiet startup in Tour mode which is why rumble is set to 0 in mode 0. If I remember correctly, Camaros don't allow quiet startup even in Tour mode and you have to go in and set it to stealth for a quiet startup. I could be wrong, but I thought thats what I remembered.

How does the flaps get the signal to open? is there a way to force it to stay close? I have a 2015 C7Z06

You can force them to do whatever you want. However, if you're asking if you can keep them closed during WOT events, that is not good. Yes you can do that, but you can also damage the motor.

Force them closed during testing only. They keep opening while in Tour, erratic. Can?t figure out why. I don?t see the active exhaust option in my tune. Is it from there where I can force to stay closed? If yes, they how come I don?t have that option showing under system?

Tour mode still had the valves open once you surpass ~ 4000 RPM.

[HNK]

Yes, but when in tour the valves open at much lower rpm or even idling or start up. I would be cruising in 7th gear around 1500 rpm and suddenly the open up and stay open regardless what. That?s why I was wondering if there is a way through Hptuners to just keep them shut

How do I go about forcing them to stay closed?

There is a thread on here and on Corvette forum that covers licensing the CCM and making changes to the NPP valves.
