Vehicles with a remapped electronic control unit may be more sensitive to fuel quality and service schedules. This was done with early engine computers in the 1980s and 1990s. Today, the term chip tuning can be misleading, as people will often use it to describe ECU tuning that does not involve swapping the chip.
Remapping is the simplest form of stage one engine tuning; it is performed mostly on turbocharged vehicles containing a modern Engine Control Unit (ECU). Almost all modern vehicles have an ECU, primarily supplied by Bosch or Delphi Technologies. The ECU has firmware that controls the various parameters under which the engine runs. These ...
The term "tuning" has been in use throughout most of the 20th century to refer to the maintenance and modification of various mechanical systems on a car's engine, with "tune-ups" being a common service offered by mechanics. The terms "tuning" and "tuner car" began to rise in popularity in the United States in the 1980s and 1990s to refer to ...
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.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company. The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
Since then, development has been iterative and today designs exist from several stages of electronic automatic transmission control development. Transmission solenoids are a key component to these control units. The evolution of modern automatic transmission and the integration of electronic controls have allowed great progress in recent years.
