Default Should you keep ORIGINAL ECM

I have a 1990 cvette & got stuck on CA smog test. Anyway (reputable shop) needed ECM swap so replaced with an AC Delco Professional rebuild. My question is should I keep the old one ($100 core I'd need to pay)? Image is of remanufactured one.

My thoughts why I ask is because it is the OEM original with tag decal and would I be wishing I kept it since the car is for the most part OEM and sell it and the value takes a hit due to non-original ECM.

only if you are going to replace it or keep the car for the next 100 years then it may be worth it

Yeah I was kinda thinking that. Worse case if I diagnose ECM "next time" I could just send this one in to be rebuilt or just get another rehab.
thx

Did the ECM get you through the CA SMOG? The shop bought/supplied the ECM or you bought the ECM and supplied to the shop?

You owe the 'shop' the 100$ or an auto parts store/jobber?
