2. Do petrol cars have ECU?
Any fuel-injected car uses a computer ( ECU ) to control the injectors and usually the ignition. Before 1985 most vehicles used carburetors and DID NOT HAVE ANY ECUS!!..

Electronic fuel injection replaces the need for a carburetor that mixes air and fuel. EFI does exactly what it sounds like. It injects fuel directly into an engine's manifold or cylinder using electronic controls.
