Another reason to change the electronic control unit map is if there are engine, intake, or exhaust modifications to the car. These "bolt-on" modifications alter the way that the engine flows, often causing the air to fuel ratio to change. Without re-mapping the fuel tables, some of the performance gains from the modifications may not be realized.
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 Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
Remapping may refer to: Tuning an engine for better performance or fuel efficiency by remapping the Engine control unit; Redefining keys on a keyboard, for example Gateway_AnyKey#Programming; Sector remapping, the automatic replacement of bad sectors by good ones in a hard disk drive
In general automobile engine replacement, a crate engine is often very competitively priced when compared to the cost of a full rebuild of a faulty engine. It is also quicker to ship from stock than to wait an equal time for parts, then to begin a rebuild. Installers often opt for the crate engine because of the cost and ease of replacement.
Mean effective pressure is also useful for initial design calculations; that is, given a torque, standard MEP values can be used to estimate the required engine displacement. However, mean effective pressure does not reflect the actual pressures inside an individual combustion chamber – although the two are certainly related – and serves ...
Engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, and mass air flow sensor. Modern engines employ the use of an engine control unit to provide the best balance between performance and ...
A host of functions required for ECU software calibration, such as interface-dependent calibration methods, calibration data management, measurement data visualization and analysis, ECU programming, vehicle bus monitoring, as well as remote control through standard interfaces, are part of the product's functional complement.
