Default Re: Low oil pressure warning - how?

Perhaps the ECM or CCM monitors it, and maybe reacts to it.
It might prevent Secondaries or kill the injector pulse?

My Buick 455 circa 1970 cuts off the electric fuel pump if the oil pressure low indicator light activates.
I would like to think the LT-5 is at least as "high-tech"?

I know cars without oil pressure gauge would light up low pressure warning light. Well, our Zs have oil pressure gauge. This makes warning light redundant. Did Lotus/Chevy allowed for low oil pressure warning sensor and then decided warning light was not necessary?
If ECM sees low pressure, then what? Shut the motor off? At 175?
