Painless Performance VATS Computer Chips
Painless VATS computer chips allow you to bypass the factory programming, making the wiring in your engine swap a snap. Since 1989, most GM fuel injection systems have incorporated a Vehicle Anti-Theft System (VATS) programmed into the stock EPROM or PCM. This means the engine will not run if it is transplanted into a vehicle without the original vehicle steering column and decoder module. If you have one of these engines and your computer has the factory programming, you need Painless VATS computer chips to make your job trouble-free.

Standard Motor Coolant Level Sensors
These Standard Motor Products replacement coolant level sensors provide the PCM with an analog input signal, along with an oxygen sensor, to go into the closed loop mode of controlling the fuel mixture. They are designed to provide actual engine temperature information to the PCM. The PCM then feeds the sensors a fixed reference voltage of usually 5 volts when the engine is on. The resistance in the sensors is high when cold, and drops as the sensors warm up, to alter the voltage signal back to the PCM. Are you experiencing temperature problems with your vehicle? Try one of these Standard Motor Products replacement coolant level sensors to eliminate any chance of problems.
