Do you guys know any way to have the valves permanently open?? Tried looking it up and didn't find anything in this forum. I assume there is probably a fuse you could pull maybe??

Thanks!

What valves? Exhaust valves? If so, set up an Individual (I*) profile on your drive mode dial. And turn it to I* with ACC ON and start the car. The valves work with vacuum and typically default to closed with a lack of vacuum. So, with no electical power to the vacuum actuator switches, they are likely closed. And you might even get a code.

i'll try that! Definitely affects the start of the car, sometimes loud, sometime extremely quiet. I was just wondering if there was some way to leave them permanently open. I'll try what you say and report back!


Thanks

Tried turning the car on but not the engine, switching it to either I/S+/or RACE and no luck........really odd how it is not the same noise on start up..
