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 ...
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.
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 ...
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
Instead of being a conventional engine, the new 3.0 L petrol inline-6 motor is combined with a 48 volt electric architecture to support an electric supercharger, belt starter-generator and extended engine shut offs while coasting and/or while stopped in traffic. The new engine is initially being offered in the Range Rover Sport in two power ...
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.
IMEP may be determined by planimetering the area in an engine's pV-diagram. Since naturally aspirated four-stroke engines must perform pumping work to suck the charge into the cylinder, and to remove the exhaust from the cylinder, IMEP may be split into the high-pressure, gross mean effective pressure (GMEP, p m g {\displaystyle p_{mg}} ) and ...
The tax horsepower or taxable horsepower was an early system by which taxation rates for automobiles were reckoned in some European countries such as Britain, Belgium, Germany, France and Italy; some US states like Illinois charged license plate purchase and renewal fees for passenger automobiles based on taxable horsepower.
