Chip-tuning - what is it?

Chip-tuning is any interference in the system management ECU car. The objectives of this intervention isto improve any individual parameters of the system, often animprovement of the dynamics of dispersal and increase torque. Modernengine designed in the light of sets of mutually conflictingrequirements on the one hand it is stricter with each year emissionstandard and moderate fuel consumption, on the other hand, high anduniform throughout the rev range torque. The task of a professionalchip-tuning is a shift this balance in one direction or another.

Modernrequirements for the master-tuner high enough: he must have goodknowledge of the theory of internal combustion engines, think of thebasic algorithms of the ECM, to be able to find and fix faults areoften detected during the initial diagnosis prior to intervention inthe management system of the vehicle.That is, before chip-tuning isrequired to be made a full diagnosis to identify faults that need tobe addressed before tuning the car.As well as identifying deficienciesin the management of DIC, which can be addressed only by individualsettings for a specific control system and style of driving. Astriking example of the shortcomings in the management system is theintegration of the engine cooling fan on the MP-7.0-controllers at107.25 ° C! (The optimal temperature of the engine VAZ - 96-98 ° C).Increasing the temperature of the engine, the manufacturer tried toreduce the toxicity of the exhaust - in the overheated engine burnsmore fuel.This is the only option to agree on the parameters VAZ motor with very stringent European standards for exhaust emissions.But thehigher the temperature of the engine, the more apparent detonationprocesses, the combustion of fuel - resulting in the computer reducesthe ignition advance angle, which leads to a drop in engine efficiencyand, consequently,improve fuel consumption and reduce engine power. Ican mention the long-suffering customers, struggling with the coolingsystem: when you turn off the engine at 107 ° C temperature blockengine is 125-130 ° C, with no circulation of coolant in the coolingsystem antifreeze coming local overheating and boiling, the pressureincreases,excess flow valve on the expansion tank is opened,letting gothe "extra" antifreeze under the wheels of the car.As a result -constant overheating the motor, further comment is superfluous.

Mostpopular in ancient times, methods of "improving" the dynamics ofelimination from the system lambda probe or highly enriched fuel / airmixture left in the past, but instead is increasingly used anindividual calibration for a specific instance of the engine.Literatesetting gives tangible addition of torque in the zone of low-mediumspeed, fuel consumption it may even slightly decrease (in a calm styleof driving, by optimizing the angle of ignition advance). Anotherdirection of chip-tuning is to set up non-standard engines varyingdegrees of refinement, including the preparation of cars for thecompetition. Popular in recent years "Iron" tuning is impossiblewithout changing the firmware.In the case of minor "iron" improvementsare limited to a simple calibration of the basic serial firmware, incases of deep refinement of the engine requires a transition tospecial versions of the firmware. Another example of the need forchip-tuning is to set the car on gas-cylinder equipment. Work onanother type of fuel requires mandatory ISP correction, disablinginjectors, a dual-mode flash, and other works, is the general term"chip tuning". There are many factory firmware, which beat recognizedas defective, they caused some problems in the management of the car.List of firmware and their defects can be found at on-chip tuning. Asa bright example is the problem with the idling speed in cars Sens.The problem is the wrong option in the firmware that is responsiblefor the way out of the idling, but it is 40 percent less than theparameter in the firmware VAZ. Another example is the sewing where thetemperature of the cooling system include a fan located in the aisles103-107 gr. at a rate of 98-99 grams. (VAZ). Such examples arenumerous ...

Specialists in tuning can be divided into two categories:
1) Professionals who are actively developing and learning, togetherwith the development of techniques and technologies. This is adiagnostician, as a rule, "in combination" minders and / orelectricians, who were many years before the injectors. There - aminority.Typically, the best advertising for them is the popular rumorand swoop to repair them to get hard - writing. They do not fuss, donot grow on the "chip tuning", considering its main occupation of acomprehensive diagnosis of all systems and competent repairs. Overtheir shoulders a great experience.
2) Another category,unfortunately, the most numerous and among the "pro" is called"pioneers". These people are usually in the service station novicesand accumulate around the auto centers and services that were not ableto reconstruct "the injector" and gladly take the work of anyclient.Typically, pioneers "very dogmatic and self-assured, are notconsidered to authorities consider their knowledge sufficient for whatwould climb into someone else's car. Determine the "pioneer" is easy -they are the first step "Chip-tune" faulty machine and easy to panicif you get from this negative result. Do not confuse a beginner andpioneer - beginner understand the phrase "You can not make chip-tuning on a defective machine, pioneers - it does not ever understand.Infact, it is people who seek to cut the easy money, stupidly alteredblock. It's the same people with whom you have repeatedly encounteredin the diagnostic stations - they, quickly connecting a computer orscanner, and found no errors tell you - everything is OK, uncle, withyou ... gr., Go ahead, the injector in order ...
