Hi guys,
My new car has a PSE fitted and I don't know if this behaviour is normal (987.2)
1/ When exhaust is OFF (light is off, valves meant to be closed) they seem to open automatically at around 5k RPM (not exactly, more like 4750ish).
2/ When exhaust is ON (light is on, valves meant to be open) they seem to close around 20mph in any gear
Is there any way to defeat these two scenarios (assuming they're not faults?). When I want the car quiet, I want it to be quiet - even if straying into higher rpm - I find it hard to believe the 'long way round' in the Sports Exhaust is so restrictive it opens to prevent backpressure. And likewise, when exhaust is open (ie, on a sporty drive when you want it to be noisy) it is a bit annoying for it to go quiet briefly and then back to loud...
I'm sure it's solvable, I assume you can just disconnect power to whatever drives the vacuum for the valves for it to stay on all the time, but what if you want it to stay off all the time? Some sort of custom wiring to always deliver power to the valves? (assuming it can't be fixed with programming/something else)
Any help would be appreciated, even a clarification on whether the scenarios I've posted are expected?
Thanks,
Jeff
