what is chip -thning?

Exists the opinion that the contemporary automobile, especially prestige stamps, the improvements do not require: allegedly, engineers introduced in the construction everything that they could. And nevertheless no-no, yes you will see advertising declarations about an increase in power and maximum torque of engine. This finishing is called chip -thningom

from where "horsie"? From the chip, vestimo

term "chip -thning" arrived at us from abroad, where the specialized tyuningovye (tyuning in the transfer from the English - tuning) studio from the series automobile make exclusive. Speech, it goes without saying, first of all - about an increase in the power of engine due to the retuning of the electronic fuel injection system. Simply stated, the basic parameters of microprocessor engine control change with the aid of the chips (microcircuits). Into that placed by manufacturing plant software are introduced the changes, which optimize formation and combustion of the fuel-air mixture: the time of the entering of fuel into the combustion chamber, proportion of fuel and air, the dosage of mixture and so forth as a result increases nominal horsepower and its maximum torque rises. It is completely regular, that affects this, also, the dynamics: is shortened run-up time from the place to 100 km/h, better "catch" bottoms, rises maximum speed.

Together with the chips is substituted tappet shaft, adapts special air filter, is established new exhaust system made of the stainless steel. Result depends on that, in which of one-and-a-half ten tyuningovykh is center the capital you they were turned. For example, PRIVATELY HELD COMPANY "today and tomorrow" works with the complete sets for boosting the engine "lorinser" and "karlsson", by the well known to the owners of "Mercedes". Company "interproyekt+" with the aid of the equipment "oyetinger" increases the power Of "audi" and "fol'ksvagenov". But tyuningovoye studio "Art- flowed" it proposes the "growth of muscles" from "MTM" ("motor technician Mayer") to owners "audi", "fol'ksvagenov", "seatov" and "damage". When desired in Moscow it is possible to find firms, which propose chip -thning for "BMV", "fordov", By "opeley" and "mazd". Over the long term to them will be added some other stamps of machines.

Support - to dynamics

effectiveness chip -thninga is visible in the concrete examples. Let us say, if you want to raise the power of diesel "Volkswagen the golf OF THE IV" to y..8GTi from 150 to 185 hp. with the aid of "MTM", then to this finishing will be required only more than two it is hour work, and to pay thousand US dollars it is necessary approximately. Planck in 232 hp. will submit after ten it is hour work and payment of approximately $4200. And this is not the limit: it is possible to bring "the herd under the cowl" to 286 "horsies", but this will engage much more than time and money. Thning- Chinese "Karlsson" for an increase in the power "Mercedes- Benz" of new S- class to 245 hp will manage approximately into $6600. Respectively for S- class valuation they will prove to be only more. however,

for which auto-owner does pay such money? In essence - for the improved dynamics. For example, if you did not stint on 1400 dollars and increased the power of 150- strong benzine motor "audi Aya" to 193 hp, then run-up time to 100 km/h from the place will be reduced by second - from 8,4 to 7,4 s, but maximum speed will grow by 19 km/h - with 221 to 240 km/h. It is possible to order more serious modernization, after raising the power of the same engine to 240 hp however this it will engage already two days it will pour out almost into six thousand "zelenen'kikh". In this case to overcome boundary 100 km/h from the place you will be able approximately in 6 seconds, and "maksimalka" it will rise to 250 km/h.

By motor you will not be finished

except the application of microcircuits, a substantial improvement in the dynamic qualities of automobile is achieved due to the retuning of gearbox by selecting of the optimum gear ratios (otherwise cursor it will "vomit" box), the installation of new shock absorbers and springs for lowering of suspension on 15-35 mm, replacing the brake assemblies to the disks of larger diameter, finishing of exhaust system and so forth in official distrib'yutorov of foreign tyuningovykh companies this modernization without fail is coordinated with the auto-producer, on that the corresponding certificate reveals.

Involuntarily asserts itself the question: why this they do not make at the plant? Answer is obvious: too expensive a pleasure. You judge themselves: a minimum improvement in the machine parameters is compared with the price of beushnoy foreign-produced brand, whereas competitive activity makes it necessary to make machines as far as possible cheaper. But the thorough modernization of engine and suspension is now and then generally equivalent to the price of new automobile. Thus, an increase in power Audi S8 from 360 to 470 hp costs order $24 of thousand, and gain in comparison with the series machine pustyashnyy - shortening run-up time to 100 km/h from 5,4 to 4,4 s and an increase in "maksimalki" from 250 km/h to 300 km/h and more.

One "treat", and another...

As in any medal, there is in chip -thninga and reverse side. After improving the high-speed indices of machine, you lose according to some other articles.

So, engine requires more qualitative fuel. If to chip -thninga automobile was calculated for the high-knock rating gasoline AI-9SHCH, then after a considerable increase in the power it is necessary to pour "98-1", which there is not on each servicing and moreover is perceptibly expensive. The fuel consumption, depending on the number of horsepower under the cowling, unavoidably will grow by 5-10%. In the principle of those, for whom is more important power and the dynamics, this strongly does not worry, but to here zealous motorists there is above how to think. But also this yet not all: the service life of motor to the overhaul with the path of 300-350 thousand km will be lowered by approximately 3-5%. All this - from the words of specialists, although in actuality the results can be somewhat different. It will become for sure in the salon only noisier, it is not excluded - will increase the toxicity of exhaust and the level of vibrations, you will more cheerlessly feel yourselves on the primings. Although, can, this and exaggeration.

V to Moscow by the described finishing of the passenger machines of foreign production on the professional basis are occupied only more than dozen companies, from which the acknowledged leaders with the large work experience of times, two - miscalculated. They carry out finishing with the observance of plant guarantee and "pump muscles" not only to the used, but also new vehicles both with the "weak" four-cylinder and with the "charged" eight-cylinder power unit. To the automobiles, which passed chip -thning, as a rule, is extended the guarantee for one-two years or on 50-80 thousand km of path.
