Nope. It will only read the air coming in thru the AFM and do what it needs with that, whether it's 5 or 7 or 10, doesn't matter.
The ECU tries to earth the solenoid whether it's connected or not but only reacts to what happens next.
I no longer have a solenoid plugged in but the ECU would still be switching the earth. I read somewhere (perhaps this very thread) that you could use this to turn on anything you want at 4500rpm eg. a light or a water spray on your intercooler etc... siren, smokescreen, ejector seat, missile launcher...
