So this doesn't seem to be harmful, but it is slightly annoying and I want to make sure it won't shorten the life of the electronic boost controller. I run Ecutek with RaceRom, and I've replaced the CPC solenoid with a Mac brand 3 way mac valve. It works great and I've got my wastegate duty configured near perfection, operating frequency is at 30hz. But, when I turn the car off, the valve will continue to operate for 5-10 seconds then turns off. If I turn the car on but don't start the engine (2 presses of ignition button, no foot on brake) it will also turn on and start vibrating/operating. I can hear it operating at idle when it's on, and this seems normal, but i wouldn't expect it to operate when off. But I'm wondering if it's receiving values similar to what it would at idle, and since it's supposed to be operating at idle it does so when the engine is off too. Any thoughts? I could configure it so the valve duty cycle is 0 at idle as well, but it seems to help not let boost spike when I initially get on the throttle from a stop, because I don't like to strain the engine with big boost and super low RPMs, ~1000. Does anyone have some experience with this, and can confirm if it's an issue or not?
