I have a '91 Camaro RS with the factory gauge cluster, and I want to know if it is controlled by the computer. MY CAR IS NOW CARBURATED. I know a guy that says that he has taken the computer and harness out of 3 different 3rd gens and the gauges still worked, but they were all pre '89 models. Mine has the newer gauge cluster in it, and I want to know if I can take all the computer crap out without affecting my gauges?

No all the computer controls on the dash is the service engine soon light.

The only gauge that is controlled by the computer is the speedometer. The computer has a speed buffer built into it that the VSS supplies pulses to. The speed buffer outputs a 4000 pulse per mile signal to the speedo, and a 2000 pulse per mile signal to the cruies control module. You could leave the computer installed with the power, the VSS, and the speedo (and cruise control, if you have it) connected to it, or remove the computer completely and get a speed buffer module for a digital dash F body ('84 - '84 Berlinetta, or ?? year T/A), and use it to drive the speedo & cruise module from your existing VSS. In pre '89 F-bodies, the speed buffer was either mounted to the rear of the cluster (analog speedo), or piggy backed on the ECM (digital T/As), or mounted behind the driver's side kick panel (Berlinetta with digital dash).
