Tuning the VAZ 2114 engine: how to increase the power of the car’s power unit

VAZ engine chip tuning

A change in the design of an internal combustion engine can be called a significant modernization, which will lead to a change in its basic characteristics. However, this tuning method is quite expensive; it can only be done independently if you have certain skills and experience, and the end result is impossible to predict. Some VAZ vehicles are equipped with on-board computers that regulate the operation of the internal combustion engine. The installed program determines the main characteristics of the engine: it affects power, speed limit, fuel consumption, idling and other features of engine operation.

When considering chip tuning, we note the following possible results:

• Increase power by 5-10%. At the same time, the possibility of increasing power depends on what settings were set at the factory, that is, whether a power reserve was left, as well as on the condition of the engine. There are cases when engine power was increased by 20%, which can significantly reduce the service life of the unit.
• Fuel consumption can be reduced by approximately 5%. Reducing fuel consumption will lead to a smooth increase in speed, that is, a quick start from a traffic light will no longer be possible. Therefore, this modification is suitable for the driver who is more concerned about savings than the driving sensations.
• Make idle smoother and more stable.

Tuning the VAZ 2114 engine by installing new firmware should be carried out exclusively by professionals, since mistakes made can lead to significant engine failures. Recently, there is no need to remove the on-board computer to read information from it and rewrite the program - the connection is made through a connector, for this a computer and a special adapter are used. During operation, only partial disassembly of the panel in which the connection connector was hidden is performed.

The work on flashing the chip looks like this:

1. Engine diagnostics are carried out to identify faults. 2. After determining the state of the internal combustion engine, a computer is connected to the chip. 3. When you connect a computer, tables with the configured settings are loaded. 4. The programmer loads preset settings, for example, to increase power by 10%. 5. After making the settings, the engine is tested and adjustments are made.

It should be understood that unique settings are selected for each engine, which depend on the state of the internal combustion engine and other factors. It is possible to carry out the work in question independently, but only if you have certain knowledge and experience. Mistakes made can lead to settings being reset and invalid parameters being set. It should also be taken into account that after chip tuning, it is necessary to perform engine diagnostics, since otherwise there is a possibility of severe wear due to the introduction of incorrect parameters.

How to increase engine power

To make the correct engine tuning, you need to choose one of several ways to modify the power unit. There are four types of engine modifications that will not cause harm to the latter and will not reduce the life of the engine.

• cylinder boring;
• installation of a new air filter device;
• turbine installation;
• chip tuning or electronic modification of the engine's brains.

You also need to take into account that as the engine power increases, fuel consumption will also increase. Therefore, before you decide to tune your engine, think about whether you need increased fuel consumption.

Increasing the volume of engine chambers

Let's consider the first method of engine tuning - increasing power by increasing the volume of the combustion chamber. To do this, the diameter of the cylinders is bored, and the surface is carefully ground to a mirror finish. The procedure is carried out on a special machine.

They replace regular pistons with forged ones, and the rings with lighter ones. Replace the connecting rods that connect them to the crankshaft.

Experienced mechanics recommend replacing oil injectors if forged pistons are installed. This is necessary for good oil cooling to occur. Since old injectors become unsuitable for further operation.

Installing a new air filter

To properly tune the engine, install an intake filter with reduced aerodynamic resistance. This ensures that air enters the mixer with the least effort. As a result, power increases by four horses.

Attention! In this case, fuel consumption is reduced, which has a beneficial effect on the car owner’s wallet.

Tuning by installing a new air filter is done as follows:

1. Grind the internal intake channels.
2. They install receivers.
3. Change the throttle valve to a new one with a larger diameter.

A direct-flow muffler is installed at the exhaust. All work is carried out in service centers. Under no circumstances should boring channels be carried out in a garage.

Turbocharging installation

Engine power is increased by installing turbocharging. Despite its great efficiency, many car enthusiasts do not dare to take this step due to the high financial costs. Installing a turbocharger requires contacting specialized workshops.

First of all, you need to choose a turbine suitable for the VAZ 2114 engine. There are two types of this device:

• low pressure turbocharger. By installing such a compressor, there is a chance to increase power by 15 percent. However, you will have to tinker with installing such a device;
• high pressure turbocharger. Increases power by 30 percent.

Another point why car enthusiasts do not dare to install turbochargers: the life of the engine is reduced. Since the motor is operated at full power at all times. Wear on parts increases and the engine heats up.

Therefore, you need to install a good engine cooling system. Under no circumstances should you pour water into it, as many car owners like to do. Always use antifreeze to cool power units.

Tuning the gas distribution mechanism

By tuning the gas distribution mechanism, you will not harm the VAZ 2114 engine. In addition, the 8-valve engine will reduce fuel consumption. And the power will be increased.

To tune the engine timing, do the following:

1. Bore the valve seats.
2. The intake and exhaust valves are changed to lightweight ones.
3. The bushings are also changed to light ones.
4. Install the split gear. But it must be configured correctly so as not to subject the engine to major repairs.

Next, let's look at what needs to be done with the split gear to increase the power of the motor.

Split gear method

To make the correct adjustment of the split gear, you need to set the piston to a point called TDC. To lower the speed or bring the speed to an average speed, make the gas-dynamic boost angle smaller and increase the angle of the opening exhaust valve.

To increase speed, the shaft is turned in the opposite direction of rotation of the crankshaft. In this case, the angle of gas-dynamic pressurization becomes larger.

There is another type of increasing the power of a domestically produced power unit. This is chip tuning. Specialists are involved. To improve engine tuning, the electronic engine control unit is reprogrammed. This is done using equipment called a programmer.

Experienced mechanics advise carrying out chip tuning in specialized workshops.

Changing the intake system

A more significant change can be called the modernization of the intake system. This method allows you to significantly increase the power of the installed engine. The essence of the method is to improve the filling of the cylinders, which reduces the intake resistance.

When considering the features of engine operation, we note the following points:

1. As the piston moves to the bottom point, resistance occurs in the air flow path, which leads to the loss of several horsepower. 2. In order to reduce resistance, the intake system must have fewer joints and irregularities. It is worth noting that ultra-precise measuring instruments should be used to identify irregularities, since a deviation of just a few tenths of a millimeter can lead to a loss of power.

In addition, tuning the VAZ 2114 engine involves installing a larger filter or one with zero resistance. Oddly enough, using a more expensive filter can significantly increase power. High resistance leads to loss of power. However, you should not neglect protecting the engine from the ingress of fine impurities. The installed filter must cope with the assigned tasks of cleaning the flow and fuel.

Features of exhaust system tuning

The vehicle exhaust system is increasingly being modernized. Oddly enough, the created resistance during exhaust gas removal leads to a significant loss of power. Moreover, almost all elements of the exhaust system affect the power indicator. This is due to the following features of this system:

• As the piston rises in the cylinder, it begins to push out exhaust gases.
• The exhaust gases can be considered as a continuous line.
• If strong resistance occurs in one of the areas, it leads to a significant increase in pressure in the system.
• If the pressure in the system increases, it becomes more difficult for the piston to push through the exhaust gases, which means a loss of power occurs.

Typically, sports cars are associated with loud noise from the muffler. This phenomenon is due to the fact that in order to increase engine power, a muffler with fewer barriers is installed, since in this case the resistance in the system can be significantly reduced. It is the barriers in the muffler that are responsible for reducing the sound emanating from the car. The solutions that are used for tuning the VAZ 2114 engine are as follows:

1. A larger muffler with fewer barriers is installed. 2. A large diameter exhaust pipe is installed. 3. In some cases, a more advanced exhaust gas removal system is installed.

Such a modification can lead to an increase in power by 10-20 horsepower. The result is not impressive, but it is worth considering that dismantling and installation work will not take much time, and the cost of modification is relatively low. When looking for an inexpensive way to improve an engine, you should pay attention to this method.

Changing the camshaft and cam profile

Tuning the VAZ 2114 engine provides for a significant modernization of the engine.

An example is modification of the camshaft and cam profile. The peculiarities of such tuning include the following points:

• A modified cam profile allows the valves to rise higher and stay open longer.
• Keeping the valve open for a long time leads to an increase in the filling of the cylinder with the fuel-air mixture.
• You can change the camshaft yourself, which requires turning or milling equipment, or you can purchase a ready-made version. One should take into account the fact that on sale you can find quite a few different camshafts that are suitable for the car in question. The main thing is to choose the right type of camshaft.

The modification in question will be inexpensive and will have an insignificant effect on the engine life.

However, the need to reconfigure the engine operation should be taken into account.

Increasing the volume of the cylinder block

Skilled mechanics can increase engine power by boring the cylinder block and increasing the piston stroke. Note that such tuning of the VAZ 2114 engine is not carried out often, as it requires significant investments.

The process of increasing engine volume can be characterized as follows:

• First you need to completely dismantle and disassemble the internal combustion engine. Only a mechanic with extensive experience can perform such work. Any work carried out during dismantling may lead to the fact that it will not be possible to reassemble the engine after the work has been carried out.
• After dismantling, the cylinder blocks are bored. As a rule, there is quite a lot of metal between the cylinders, as well as the cooling system channels. A few millimeters can be removed in order to increase the volume of one cylinder. However, it should be taken into account that all cylinders must be bored equally, otherwise the internal combustion engine will not work correctly.
• Due to the increase in the diametrical size of the cylinders, larger diameter pistons must be used. This point also significantly increases costs.
• To increase the piston stroke, a new camshaft, connecting rods and other elements of the piston system are installed.

The design of an internal combustion engine is quite complex.

In this case, all dimensions are maintained with a deviation of several hundredths of a millimeter. Therefore, it is almost impossible to independently increase the volume of an already installed engine without certain equipment and skills.

THEME FOR THOSE WHO WANT TO MAKE KALINA MORE DYNAMIC AT A LOW COST.

1. I decided to make my KALINKA more powerful and dynamic. Chiptuning gives an improvement, but not enough to be satisfied. I decided to move on.

2. AND SO – WE REPLACE the engine camshaft (we are talking about a 1.6 liter 8 cl. engine). For replacement, I chose the camshaft OKB “DINAMIKA” 8-266-101, which gives a power increase of 15 hp. and torque increase 16 kg/m.

3. For a new camshaft, we change the firmware for it. (but to fine-tune the firmware you need a JANUARY 7.2 controller (but not 7.2+).

All the work was carried out at OKB “DINAMIKA” only because of the stitching for the 101 camshaft (although mechanically I can do everything myself).

4. And so I drove it - I feel that the torque on the shaft has noticeably increased at all speeds. BUT. IRON IS ONLY 50% OF SUCCESS.

I feel that the firmware for this camshaft is NOT GREAT.

JUST AS I myself have previously installed and adjusted similar camshafts on carburetor cars - and I know what they are capable of.

5. I went to PAULUS to finalize the firmware for the 101 camshaft!

GOOD FIRMWARE is the second 50% OF SUCCESS.

My KALINKA ran completely differently!!

The acceleration dynamics have become noticeably better, from the very bottom all the way up to 6000 rpm! On the road, many cars and foreign cars are also inferior to me in terms of acceleration dynamics! DRIVING BECAME MUCH MORE CONFIDENT AND CALM (psychologically I am confident in my car). )

I expected that with an increase in power fuel consumption would increase - IT DID NOT INCREASE. (let me remind you of the PAULUS firmware - 50% success). Just recently I made a trip along the GOLDEN RING (600 km) (Vladimir, Suzdal, Gul Khrustalny), the car load was 100% - 5 people in the car and luggage.

CONSUMPTION – 5.9 l/100km. Moreover, I was driving without saving 100-120 km/h while overtaking at 140 km/h.

Now the average consumption (city-highway) is less than 7 liters.

YOUR CONSUMPTION WILL INCREASE BECAUSE THE CAR DRIVES BETTER AND YOU WANT TO PRESSURE ON THE GAS HARDER!

I AM SATISFIED WITH THE CAR.

ALL COSTS for engine tuning are less than 15 thousand rubles (of which 4 thousand rubles are for the purchase of JANUARY, all BOSCH).

ANOTHER VERY SUBTLE QUESTION! WHY I CHOOSE 101 CAMSHAFT.

1. For some reason, everyone is trying to install semi-sport camshafts (106, 107, 108, 109) which give an increase in power and torque at high speeds of 5000-7000 rpm. BUT. Such shafts have a small increase in TORQUE (or no increase at all) at LOW and MEDIUM speeds, which sometimes results in a loss with conventional camshafts during normal driving.

To drive normally (dynamically) on such shafts, you must constantly spin the engine to high speeds of 5000-7000 rpm. - and often you drive in this style - only at races.

2. THEREFORE I chose camshaft 101 which gives a noticeable increase in TORQUE from idle speed up to 5000-6000 rpm. which, during normal driving, gives a huge gain in acceleration dynamics right from the start.

Although you can race with this camshaft, I can easily argue with foreign cars with engines up to 1.8-2 liters in volume!

HUGE THANKS TO VLADIMIR GOLUBEV AND THE WORKERS OF OKB “DYNAMICS”!

Tuning in the service

The issue of engine tuning has been relevant over the past few years. This point determines that many car services provide a similar service. Often, a car service center carries out chip tuning, but they can install a turbine, increase engine capacity, carry out cylinder head and many other works.

When ordering a service from a specialized company, you should consider:

1. The price of the work will be quite high. At the same time, you also need to add the cost of new parts. As a result, in many cases it is easier to install a new engine than to change the old one. 2. The quality of the work performed will be at the highest level. A rather important point is that the modernization will be carried out by experienced motorists and mechanics. Many aspects cannot be foreseen when doing work independently. 3. The work is usually completed in a shorter time, since the people who carry it out have extensive experience and devote all their free time to this matter.

The above points determine that the best results can be achieved if you seek help from a specialized center.

What's the result?

As you can see, engine tuning, including classics, in terms of the scope of work largely affects the BC and cylinder head. However, we should not forget that the carburetor will also need tuning. It is not surprising that a forced engine requires more gasoline and air, that is, the carburetor also needs to be upgraded and tuned.

As for the parts for the internal combustion engine, everything will depend on the specific tasks. If the budget allows, it is best to install special connecting rods, replace cast pistons with forged ones, replacing bearings, etc. is also recommended.

Finally, I would like to add that if all the work is done correctly, then even a significant increase in engine volume does not greatly affect fuel consumption. Moreover, consumption may drop. The fact is that better traction, elasticity and throttle response of the engine after modifications allow you to spin the power unit less in lower gears for acceleration and maintaining the usual driving pace.

The main thing is to correctly configure the carburetor and ignition system, taking into account the changed working volume of the internal combustion engine. As a result, a forced engine increases the operating comfort of the vehicle, and the procedure itself is often cheaper than swapping an engine or, moreover, installing a turbocharger on a carburetor with minimal modifications to an existing power unit.
