About Chiptuning
Introduction
The operation of the auto engine is managed through a pc (ECU) upon the facts supplied by indicators in the engine compartment. All the facts from the indicators reach the ECU and at the same time as setting a Chiptuning the commanding chip of the car computer is reprogrammed to obtain upgraded performance and most effective operation.
Parameters
In the case of petrol fuelled (suction) engines without charger a 10-12% growth of output may be reached. The increase of the torque in those cases is among 10-15%. In case of charged (turbo or compressor) engines the increase of output may be among 20-30%, withinside the case of sure models it could be even 40%. The increase of torque is among 20-40%. It is exceptional that a better torque is available at low engine revolution (rpm), permitting our vehicle to accelerate more dynamically withinside the whole rpm variety after the motor optimization. We can redifine the pleasure of driving in our very own car with none mechanical transformation. If in the future eg. in case the car is sold and the brand new owner will prefere the manufacturing facility settings, the authentic characteristics will be reset free of charge in all cases.
Differences
Modern time vehicles are mass produced, the element parts of the engines are manufactured with certain margin which bring about variations among the engines assemled with the aid of using these parts, there are no identical ones among them. From overall performance point of view the distinction between engines of the same model can attain as much as 5-10%. The manufaturers but usually take the more economical solution and for that reason the end result is that different engines of the equal type get the same commanding program fitted. Deriving from many manufacturing margins every vehicle has reserves disponible which we are able to use through the optimization of the motor.
Functioning
The command program is located in the computer of the car (ECU: abbreviation of Electronic Control Unit) in a statistics storage unit. The chiptuning lets in individual settings for every car, this way we are able to optimize the engine operation, which ends up in higher efficiency more economical operation and in regular operational conditions a decrease of consumption. All the data of the senzors, detectors of the motor compartment attain the ECU upon which the evaluation and command is completed, for e.g. how much fuel, pre-ignition, turbo chargeing, etc. is wanted in a certain moment. The setting of those parameters of the engine is changed at some point of chiptuning in harmony with each other, according of the kind of the car and within the limits determined through the manufacturer. The setting of the different parameters is completed depending from the RPM and the load.
The process of Chiptuning
The manufacturer software program is read, saved, than follows the setting of the parameters. In every case the very software program of the producer of the car is changed, no program of any similar however otherwise equipped car type is applied. During an individual application most effective parameters of the engine functioning are modified, all of the similarly settings continue to be intact. The real circumstance of the engine, kms completed, driving style of our client, his/her requests are taken into consideration, for e.g. the upper restrict of revolution is ready as requested, the reaction of the accelerator pedal is adjusted to the foot, etc. A perfect setting requires the harmonious modification of all parameters belonging to the engine operation which permits an experienced professional to modify the driving properties of the car according to the requirements of the driver.
Results
The Chiptuning will now no longer modify the operation of the functioning of the diagnostic instruments so the ones will communicate with the pc of our car the identical manner after optimization as well. No change of idle, no manage laps lid and reading of mistakess messages may be accomplished without problem. Summing up, our car may be perfectly operational after optimization, the motor will be more elastic in functioning, it’s going to boost up better even in the decrease revolution range, shifting may be made in advance in order that no extra excessive revolution may be had to gain the desired acceleration. No shiftback need in overtaking, or on rises, accelerator pedal response and performance/weight ratio of the auto are progressed and this manner the consumption will be 5-15% much less in normal operational conditions. Output may be more evenly distributed in all revolution ranges, the turbo-hole effect may be eliminated, or decreased (depending on models), the reserves of energy of the engine may be utilised greater efficiently. This is to bring about more dynamic driving experience, which is likewise felt in case of smaller ccm cars, in spite of climatization turned on.
Safety
In case of automated gearbox cars (e.g. the BMW X5 3.0D), it is able to be felt that even as accelerating the engine only reacts with numerous tenths of seconds delay, which (converted into the distance made) will mean 2 meters in line with 10th of 2d at a speed of seventy two kms/hour. In everyday transit there are conditions when steering and rapid accelerating provide the answer instead of braking. With Chiptuning this delay may be elaminated, the engine reacts right away for the pedal and we are able to avoid an accident (even a frontal collision) at a certain situation. Upon optimization our car disposes of extra reserve of output capacity wich offers us convenient feeling of protection in cases of overtaking or in critical conditions.
