NPP functionality retrofit?
Hi, everyone
I have a third-party vacuum-controlled exhaust with a small remote that controls the solenoid for the valve. I want to make the "we've got NPP at home" kind of thing and tie it to the Sport mode (I've got a V6 so no Track mode for me). Is there a way to tap into a signal from the ECU (or BCM?) that tells whether the car is in the Sport mode? The rest of the job is pretty simple, I just need something to tap into If anyone knows how to retrofit the NPP that would be even better - this way I will replace the valve with the electronically controlled one and get my signal from the valve solenoid (I will also need it for the AirLift system to change presets) |

Don’t think anyone’s tapped into the BCM like you’re saying, someone on the Corvette forums was making a retrofit for the OEM NPP but they unfortunately stopped posting.
Best option imo is just adding up switches for everything

Thanks for weighting in on the subject. Yeah, I thought of that too. Main issue still is that I have a basic 7’’ head unit and to control that exhaust I need a 8”. Still maybe there’s someone dedicated enough that did it)

![]() I'd still contact them and ask about feasibility, because even if you source a 8" screen, you'll need custom programming and potentially a replacement HMI module.
