All Things Honda Civic Si

The ECU or engine control unit can control a number of different functions on an internal combustion engine. In the simplest applications they will control nothing more than the amount of fuel which is injected into the engine. In most modern applications they can control the amount of fuel injected, ignition timing, valve timing and even the boost level obtained from a turbocharger or supercharger. The Civic Si ECU (engine control unit) is tuned from the factory for a high degree of performance. There also a number of manufacturers who build aftermarket ECU chips for the Civic Si which are generally capable of offering an even further performance boost. Many of the aftermarket ECU’s are also capable of being programmed. This will allow a driver to modify certain settings which can enable either an increase in power or fuel economy.
