Chip-tuning with your own hands - you love to ride, love and strain
Chip tuning with your own hands - a phenomenon already quite common in our realities. Russian men - they are: let me just save on a trip to the service station, if you can solve a problem with a friend in the garage. Although, of course, the chip tuning of the engine with your own hands is not the easiest procedure, and if something goes wrong, there is a risk to significantly stump both the nerves and the wallet.
Chip tuning do-it-yourself for beginners - the basics
Where did the concept come from - engine tuning chip? From those times when the trees were still big, the girls were prettier, and the first electronic control units (ECU) had already appeared in the cars. It was then that some particularly intelligent car owners realized that if there are chips with a processor and a controller that define certain parameters of the engine, then you can replace them as well!
The first chip tuning with your own hands - it really was chip tuning with your own hands and, in addition, a soldering iron with rosin and solders.In words, the manual is very simple: I dropped one chip from the board and soldered another with pre-wired parameters. And voila! - the car is already going differently.
It is often better, sometimes worse than it was. Then I had to repeat the procedure. Now everything has changed: chip tuning with your own hands has become much easier - a laptop with special software, a connector for diagnostics, a programmer - and go! In fact, the current chip tuning with your own hands is the same flashing as with modern smartphones. Responsibility, perhaps, more.
How to make a chip tuning engine with your own hands - and what it will give
It is no secret that many owners, especially those who already have a certain experience of driving their car, would like to somewhat improve some of its characteristics. The most common requirements are as follows: either to improve the dynamics of the car, or to reduce fuel consumption. Do-it-yourself chip tuning is the easiest way to do this, and perhaps the most affordable for the average driver.
Do-it-yourself chip-tuning — interfering with the engine's control electronics to change some characteristics — can be of varying degrees of depth: either a complete flashing or a replacementcontrol electronics, or a milder version: intervention in the database of the standard on-board computer of the car.
There are special tuning kits: for example, the German RaceChip or the Belgian Remus Powerizer promises a power increase of up to 30%, coupled with 10% fuel economy, while maintaining the usual style of riding.
In fact, such chip tuning boxes, which are visually an ordinary plastic box with a “printer” connector, can be installed on any type of engine - both gasoline (atmospheric or turbocharged, not so important), and diesel ones. Its feature is a shallow interference with the operation of the engine control unit, and not a classic flashing.
Chip-tuning the engine with their own hands - the pros and cons
The main disadvantage: with a complete flashing of the control unit, there is a risk that something will go wrong somewhere - as when reinstalling Windows, for example. But if on a regular computer it is easy to roll back the system or re-roll it, then everything is a bit more complicated with a car.
In the saddest cases, you can say goodbye to the old electronic control unit. And the chip-tuning-boxing technology implies the addition of an on-board computer information base,engine manager, various data necessary for the motor to operate in various modes, initially “wired” in this unit.
One more plus of such chip tuning boxes is that they are not detected by diagnosticians at the service station of official dealers from whom the car was purchased. And, of course, this does not entail withdrawing from the warranty service - which is also important, especially for owners of two-three-year-old cars with low mileage. By the way, another important point: after installing the chip, you need to drive 150-200 kilometers - so that it can be calibrated and the work is coordinated with the ECU.
Usually, after installing the chip tuning box, the car becomes more responsive to the gas pedal, accelerates somewhat more dynamically (here it is still important to take into account the initial parameters of the engine - for example, a VAZ chip tuning with its own hands will not give, for example, the top ten Mitsubishi Lancer or Subaru Impreza) and brings more positive emotions to the car owner.
Chip tuning with your own hands - how it works
The engine has a computer that “speaks” when to spark a candle and how many nozzles pour gas into the cylinder, when to start blowing the turbine and with what effort - all this is controlled by one small box,which can sometimes be in very unexpected places. Chip-tuning with your own hands allows you to change the program that is stored there, and which contains all the factory values of certain parameters of the car engine.
It's simple: a diagnostic connector, a connection to a computer, a “cream” of the old firmware, and a “knurling” of a new one. The essence of the current chip-tuning: to come to the service station to the guys with a laptop, by car in 120 hp and for the conditional 5 000 rubles to remove from your engine already 150 hp - and this is not magic.
There are various fuel cards in the engine that are regulated by several parameters - they, with a certain skill, are downloaded and changed: many engines today have an extensive resource for increasing power - they are, for the sake of ecology, even “extinguished”.
The ignition is not optimally set - if you change the angles, force a spark to light up earlier and give more fuel from the nozzle - you can easily add 10-15% of power from the atmospheric motor. If the engine is turbocharged - change the algorithm of the valves of the turbine.
As a result, it starts to blow earlier and stronger, plus all the same with ignition and injectors - this can give up to 30% increase in power.And most importantly, without losing the resource characteristics! The most fertile ground for chip tuning is turbo diesel engines: the work will give an increase in power, plus fuel consumption will remain the same.
Most often and most effectively, the chip tuning looks on the engines that are delivered to Russia and Ukraine with a much lower degree of boost - the tuners simply fill in the “European” or “American” firmware - it works 100% efficiently and safely. It is also worth “chiping” to transfer maximum torque to lower engine speeds.
They are the most working - and remove the "microflaps" during acceleration. This is a plus! The main thing is not only the increase in power, but also the increased elasticity of the engine. Although if the motor is not very good from the very beginning - it cannot be fundamentally corrected by any kind of “chipovka”.
Chip tuning with his own hands and his dangers
It is more difficult, if the characteristics of the engine start changing for the sake of their whims - then the engine starts to work in several uncharacteristic modes. Which often affects its service life. Another problem: those who are engaged in chip tuning in Uncle Vasya’s garage, can sometimes be dishonorable.For example, instead of flashing, such comrades can simply change the response to the gas pedal - by installing the so-called “jetter”.
The fact is that the engine's electronic unit “feels”; when and how you press the gas pedal, a third is pressed, and it will add a third to the fuel. They pushed more thoroughly - the nozzles will open to the full. With the “Jetter”, whenever you press the pedal, the car tries to tear off, like Usain Bolt. That's all change. Fuel consumption at the same time, of course, certainly will not decrease.
In general, if you decide to do chip tuning yourself - find all the information about your engine, its power characteristics. The Internet is big, everything is there. How to check the performance? Only measurements on the stand. In the stock version and the “cracked”. We look at the graphics and compare.
Remember that as a result of an unsuccessful chip-tuning, irreversible changes in the operation of the engine can occur, which can lead to very expensive repairs. By the way, if you “chip” a gasoline turbocharged engine, you will have to switch from 92th or 95th gasoline to 98th. And, of course, there may be a problem with the gearbox: if it doesn’t sever because of the increase in power and the increased torque, it starts to wear down the gearbox anyway.
And the funniest thing: if you bought a used car, which was already “chipped”, and the previous owner didn’t say anything about it, then you can fill in exactly the same custom firmware as it was. It's funny, but a fact - you can pay money (usually - from 150 to 400 cu, depending on the degree of difficulty and depth of work, but chip tuning boxes can do even more expensive) - literally for nothing.
