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 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 new engine is initially being offered in the Range Rover Sport in two power outputs, 360 PS (265 kW; 355 hp) and 400 PS (294 kW; 395 hp). Both are considered to be mild hybrid electric vehicles. The 48 volt electrical architecture JLR announced with this new engine is similar to Mercedes-Benz's "EQ Boost" and Audi's 48 V systems available ...
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 displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...
It is an administrative unit originally calculated partly from the power of the engine and used to calculate the amount of tax that may be due at the time of registration. The Citroën 2CV (two tax horsepower) was the car that kept such a name for the longest time. Its use in France dates from 1 January 1913.
