WHAT IS REMAPPING?
Car powered injection system has a device called a control unit or controller. It is a specialized computer called a “Engine Control Unit ECU at a glance. The unit is responsible for the performance of the engine under all conditions of speed and load. Operating parameters are stored in table form and are placed in memory of the ECU. Chiptuning optimizes the parameters of the table in order to increase flexibility and efficiency in the rev range above 2500 rpm. As a result, chip tuning to obtain an increase in capacity from 8% for petrol cars without turbo and 30% for turbo cars and the TD. Since the compression and the maximum speed is increased is also a slight increase in fuel consumption. However, the average fuel consumption in the mixed cycle (the route and the city) remains unchanged.
CHIPTUNING WHY IS NOT PERFORMED DIRECTLY IN THE FACTORY?
Prametry entered to the ECU, as well as the program is being developed by the manufacturer with the aim of optimizing incomplete, resulting from three main reasons: – The engine sometimes long runs despite failures of control and power is sometimes poor quality fuel, and supplies used are averages and are not replaced in time. The manufacturer’s margin of safety on the one hand saves against the failure of users who do not care about your car and do not provide him the basic service, but on the other hand consumes fuel and lost power. This margin is not less than 15% for cars without a compressor, approximately 50% (half power!) For cars with the compressor (data: GM / Opel). Chip tuning improves these parameters. – The car must have a low fuel consumption – but, as calibrated for speed (90 and 120 km / h), manufacturers of patient performance and reduce fuel consumption at these speeds for 4 and 5 gear creating an artificial “holes in the gas.” High speed limits to less than 3000 are intended to improve performance levels in the urban cycle – but car loses much of the flexibility (chip tuning these parameters increased)
– Fees for cars in Western Europe are dependent on engine power, so most of the cars offered in the German market has less power than their counterparts at Japanese markets or the U.S. – although the same torque. Honda 1.4 VTEC engines offered in Germany have the power to about 75 hp, while in Poland have 75 or 90 hp. In Japan, the same engine develops 100 hp.
Overall, therefore Chiptuning change of engine control software on your computer in order to obtain higher efficiency, power and torque, and possibly reduce the bit consumption at a constant driving style.

TDI CHIP TUNING
It is also possible to modify any computer without removing the turbo and the exchanges of the chip by external modification of parameters by plugging the module (which takes an average of 15 minutes, 80% of the do it yourself) – but then the performance is slightly smaller than using the basic version of the chip – not to mention the enhanced versions. But do not call it just a module or chiptuning Box for diesels, because the chip in your ECU is not modified, and changes are just some of the signals generated by a computer and appropriate feedback signals from the sensors in order to extract greater efficiency. Performance is lower because the controllability of the method to modify the external signal is slightly worse than in the case of a change chip (where controllability is nothing more restricted). The advantage, however, is ease of installation. It is worth noting two important details – the first is the durability of the engine, which, with respect to deadlines for replacing supplies remain unchanged – and the second is the fuel consumption, which may indeed increase slightly with hard use (up to 10% – because the engine will be stronger – nothing is totally free), but is lower on large distances and when driving at constant speed. Chip tuning is absolutely necessary when installing a turbo or supercharger. Shortage of fuel would destroy the pistons and valves at a rapid pace and knock … better left unsaid.CHIP-TUNING AND MAXIMUM POWER ...
It is here to explain one important thing – most people are interested in maximum power. But it does not drive a car at maximum power, unless he is a racer. In fact, the maximum power is not an indicator of the effectiveness of any tuning. What is important is that the car can reach at 6000 rpm. power of 100 hp at 3500 has only 68, and at 2500 only 47 (eg BMW 316i). Obtaining a great acceleration of the enhancement of the car along the axis of rotation through the chiptuning – even if power max. remained unchanged – car pulls to the front and easily wins against seemingly stronger opponents. Well that just create a car that had 300 hp with 2 liters, while at 2000 rpm. finding it hard to pull the top three (example – Ford Cosworth WRC 96 – 312 hp – 7200 rpm., 192 hp – 5500 rpm. 86 hp – 3000 rpm., 30 hp – 1900 rpm /. min., the default engine). Reasonable indicator of the dynamics of the motor torque. The determinant of the efficiency and effectiveness is the average power expenditure calculated as the average weighted effective power of the engine throughout the rev range. This sounds complicated but it can be really quite simple. Suppose we measure throughout the day on which speed up your engine turns, at 1 / 10 sec. Then we see what he develops the power of these revolutions.
Calculating weighted average basis, adding this new capacity multiplied by the coefficient of demand for these particular sales all day long. Low-speed range Checkweighing doubling its percentage if we are interested in speeding up or leave it as it came out of measuring, when we are interested in power. We optimize the above parameter. A maximum increase in power? Well, its kind of leeched for effect. We raise it to 8% for example, by introducing additional fixes for certain specific rotation. It is also important when someone actually decides to see how much faster can go … Only those seats so expensive … :-). We see it like that. Look at it like – you can have 90 hp and start to win the 120 hp car – a better average power. What else speed. Here it will not win – the maximum power counts.

MANUFACTURER'S WARRANTY AND
A very important problem is the issue of manufacturer’s warranty. If the chip is listed in your computer is theoretically leads to loss of warranty. However, most modifications are made in such a way as to be undetectable service equipment of the car brands in the standard static tests to be carried out by way of guarantee. However, more advanced study egzaminer (eg, any dynamic tests performed on the occasion of reporting faults) may show differences in relation to factory settings. It follows that, during normal no clam contacts with the service warranty at the most to lose if you approve of the fact that the modification is in the computer. A separate issue is the TDI module and clip-on modules from the chip or computer software plugs and entered into the computer through the diagnostic port. You can always remove the clip-on device to the service time and review. For programs listed in the computer via OBD2 service is not possible to detect the modification, with the exception of any previously described dynamic tests, assuming the use of highly advanced type of examiner.SUMMARY...
It is worth noting that:- Chip-tuning does not affect engine durability while maintaining deadlines exchanges supplies
- Chip-tuning does not increase fuel consumption
- Chip-tuning the car’s power increases, but mainly to improve the torque and optimizes the supply to the engine under the assumption of good fuel
- Chip-tuning allows you to give the individual nature of work in the serial car
