An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
Of all the electronics in any car, the computing power of the engine control unit is the highest, typically a 32-bit processor. [citation needed] A modern car may have up to 100 ECU's and a commercial vehicle up to 40. [citation needed] An engine ECU controls such functions as: In a diesel engine: Fuel injection rate; Emission control, NOx control
Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine ...
The final car to use K-Jetronic was the 1994 Porsche 911 Turbo 3.6. Fuel is pumped from the tank to a large control valve called a fuel distributor , which divides the single fuel supply line from the tank into smaller lines, one for each injector.
One of the key features of the Adaptive Platform is service-oriented communication since the Platform is based on the Service - Oriented Architecture. [24] Adaptive AUTOSAR is developed and written using C++ which is an object-oriented programming language. The communication protocol used for the in-vehicle networking is SOME/IP, based on Ethernet.

Cars with a turbo fitted can have the requested and allowable boost levels raised, these applications usually have the most effect if the turbo fitted is a low pressure turbo which leaves the most room for improvement. Another reason to change the electronic control unit map is if there are engine, intake, or exhaust modifications to the car.
