TDI Remap
Turbocharged Direct Injection or TDI is a design of turbo diesel engines, which feature turbo charging and cylinder-direct fuel injection, developed and produced by the Volkswagen Group. These TDI engines are widely used in all mainstream Volkswagen Group marques of passenger cars and light commercial vehicles produced by the company (particularly those sold in Europe). They are also used as marine engines - Volkswagen Marine, and Volkswagen Industrial Motor applications. IN simple terms, TDI is an acronym for Turbocharged Direct Injection. This type of engine has turbo charging capabilities as well as direct fuel injection. It was made by the Volkswagen group. It is known to offer high efficiency and higher power output with little emissions. These engines are diesel based. The Direct Injection Engine was considered to be the savior of diesel, and there has been a growing market for TDI diesel cars. These cars are perhaps the most interesting in their creation, as they attempt to get the benefits of a gasoline engine, including fuel efficiency and engine power, without sacrificing the low cost fuel and environmental importance of diesel. The TDI is important to car makers as it offers them the chance to produce a car which does not lack for performance power. However, as with any other environmental technology, there are many pros and cons to producing and using TDI diesel cars. When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU's program or 'map' to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions. ECU remapping is taking a read from the ECU's processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.
