Computer in 81?
Hey folks, I remember reading somewhere that 81 Corvette's have computers in them, is this true? If so, what does it control? Thanks in advance folks...

All '81 engines has a carburetor with the "Computer Command Control" unit that originally came with the '80 LG4 305ci California only Vettes. The 1981 version automatically adjusts fuel mixture and ignition timing up to like 80 times per second.

It controls the mixture on the primaries only & adjusts it 10 times/sec, based on coolant temp, throttle position, manifold vacuum & the O2 sensor readings. The secondaries work exactly as non-computer controlled Q-jets do.

Is it possible to and what effect would it have unplugging it?
I suggest you don't unplug it. Trade it for a '79 like mine.

Yes, it can be unplugged, but that will trigger the Computer Command Control's imbedded satellite transceiver which will send an automated signal to General Motors and the Federal Environmental Agency notifying them of your breach of the 1981 environmental regulations by the disconnection of the unit. EPA agents will track your vehicle with the assistance of GM's On Star, and eventually a black Suburban with Government agents and GM officials will show up at your door, most likely at 1 AM, and take you into custody for interrogation. Your Vette will also be impounded, dismantled and combed for evidence. I hope you like bright lights in your face, because they will use them while pumping you for your reasons for disconnecting the unit. Once you crack they will take advantage of the opportunity to plant hypnotic suggestions that will reprogram you, turning you into a staunch environmentalist. Suddenly you will wake in your own bed, refreshed, and you will find that your Vette has been replaced with an "EV II", GM's prototype for it's next generation of electric vehicles. Oddly, it will never occur to you to question the change in transportation, and instead of going on cruises and to classic car shows with your Vette buddies, you will be content with spending your weekends hosting tupperware parties and going to "chick flicks".
I suggest you don't unplug it. Trade it for a '79 like mine.

I thought the GM guys/Agents were driving Tahoes now. They get better mileage than Suburbans.

Well you can get 3rd row seating in a Tahoe, but you would not have as much room in the back for a mysterious black box. My mistake.
