First, why do you want to disable the computer? Second, if you are required to have the car emissions tested where you live this is grounds for failure. Third, what engine do you have?

At a minimum the computer controls the distributor advance, the carb primary side mixture, the idle speed, the trans converter lockup and the evaporative canister solenoid. On the VIN Y 307 it also controls the A/C compressor clutch. At a minimum, removing the computer requires that you change the distributor to an older HEI with a vacuum advance canister and the carb to an older Qjet without the mixture control solenoid. If you still have a lockup converter trans you'll need to rig a switch or get an aftermarket lockup controller. None of this will provide dramatic improvements to a 307, which runs pretty well if all the factory installed equipment is working properly (including the miles of vacuum hose).
