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 ...
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
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.
EEC-III on carbureted cars controlled the same Ford 7200 VV carburetor as the EEC-II. On fuel-injected cars, the module fired two high pressure (approximately 40 psi) fuel injectors that were mounted in a throttle body attached to a traditional intake manifold in the center valley of the 5.0 liter (302 cid) engine.
