 The Z28 was still powered by a V8, however due to new emissions regulations the engine was now equipped with a CCC (Computer Command Control) unit for the first time.This predecessor to modern engine control modules had an oxygen sensor, an electronically controlled carburetor, a throttle position sensor, coolant sensors, a barometric pressure sensor, a Manifold Absolute Pressure sensor (MAP), and a check engine light on the dash.The transmission was now equipped with a lockup torque converter, controlled by the CCC as well.
