The heart of the TCCS system is a microcomputer. A microcomputer is a device which receives information, processes it, and makes decisions based on a set of program instructions. The microcomputer exercises control over the output actuators to carry out these instructions.
The use of microcomputers has taken the science of engine management into the space age by increasing the speed with which information can be processed and allowing the electronic control system to manage more engine functions. With the ability to process information so rapidly, the modern ECU is capable of carrying out its programmed instructions with extreme accuracy. Engine management can address virtually every condition the engine will encounter so that for any engine condition, the ECU will deliver optimum fuel and spark.
