The car engine is the main power unit, on the characteristics of which much depends. Every year, the design of internal combustion engines becomes more complex and more efficient. However, this point does not apply to domestically produced cars - the installed engines are improved only in appearance, in general the design remains unchanged for many years. In order to significantly improve the driving performance of the car, the power unit should be modernized.
Sidebar: Important: With the right approach, you can significantly increase power or reduce fuel consumption, make engine operation more reliable, and make the sound more attractive.
Let's look at all the features of how to tune a VAZ 2114 engine: methods, possible improvements, problems with modernization and much more.
Removal and installation
It is quite easy to remove and install the hood of a VAZ 2114 yourself, without resorting to the help of a car service. How to do this will be discussed further. The hood is held in place by hinges located along the rear edge of the front part of the body. There is a hood lock with a hook at the front, which prevents it from opening while the car is moving. In the open position, the hood rests on a metal stop. The lock has a cable drive with a handle, which is located inside the cabin under the instrument panel on the left side.
In order to remove the hood, you need to open it and put it on the stop. After this, you need to disconnect the windshield washer tube from the tee, and also disconnect the electrical wires from the engine compartment lamp. Now you can unscrew the four bolts securing the hinges to the hood. It is advisable to have an assistant nearby at this time to hold the hood up. By unscrewing these bolts, you can remove the hood of the VAZ 2114 from the body. The withdrawal operation is completed. Installation is carried out in reverse order. But at the very end, before tightening the fastening bolts, it will be necessary to adjust the gaps between the hood and the body wings.
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.
Many owners of domestic VAZs of the fourteenth model make certain improvements in the design and appearance of their “horses”. For example, modifications to the steering rack, tail lights, heater, locks, cylinder head, throttle body, engine, trunk, cooling system, doors, brakes. Modifying a VAZ-2114 at home is a fun and rewarding process. Useful because the result always pleases the owner. This article will look at a few of these options.
Other Possible Causes
If the problem is not a violation of debugging, it means that one of the parts of the locking system has broken. Let's not consider the option of the integrity of the lock: I think you checked it first.
One of the most likely failures is fatigue of the metal from which the spring inserted into the radiator “TV” is made. As a result, it weakens and stops working as it should. Its weakening can often be easily detected by simply pulling on it: the resistance will be quite weak. The spring is changed, the hood fixation is restored.
The next element that quite often breaks or becomes loose is the support tins under the spring. In this case, you can close the hood, but this requires 2 people: one pulls the handle that opens the lid, the second slams the hood, and only after that it closes. The fact is that when installed, the spring should not close the entrance to the lock guide in the center; it should be shifted to the side and cover this sector by 30 percent, no more.
If the condition is not met, the support washer bends and there is no engagement. You need to straighten the tin and place a washer under it while tightening the cable.
A way to eliminate the last defect may be to shorten the cable. However, it is better for a non-professional not to do this: there is a high risk of damaging the cable itself. If you decide to go this route, it is better to go to a service station. We have listed the main reasons why the hood on a VAZ 2114 does not close; Let's hope that our advice will help you improve the situation. And it’s even better if they are not useful to you at all due to the absence of such a problem.
Modification of the rear lights of the VAZ-2114
There are many options for modifying taillights. Here are a few of the most popular:
- individual LED elements;
- LED rings;
- LED inserts and overlays.
For individual elements of LEDs, LED strips or rings are used; for the body, reflectors of different sizes and corresponding colors are excellent, which can be purchased without much difficulty in automobile stores.
The paint is also selected according to your taste and desire. In order to place the rings in separate cylinders, you can use tin cans, after carefully cutting out the desired size. If you decide to mount LED trims inside the headlights, then do not forget that they are mounted on top of the rear optics. In any of the listed options, you cannot do without soldering iron skills. If you don’t have the skills, but want to modify the taillights, then it’s better to contact a tuning studio, where professionals will do all the work for you.
Adjusting the lock
Adjusting the lock may be necessary when the hood does not close well or you have to exert quite a lot of force to close it. This adjustment is also necessary if there is vertical play in the hood when it is in the closed position.
In addition, hard impacts when closing, as well as difficulties when opening, also require this adjustment. In order to complete this procedure you will need:
It is necessary to loosen the tightened locknut while holding the latch with a screwdriver to prevent turning. It is very easy to adjust the height of the latch. To do this, you either need to wrap it or, conversely, unscrew it. To adjust the horizontal position of the latch, move it in the required direction. After the adjustment is completed, you need to make sure the lock is working correctly. If it still does not close or any defects still remain, the adjustment procedure will need to be repeated.

A relay is an electrical device that is designed to close and open various sections of electrical circuits with given changes in electrical or non-electrical input quantities. Show in full…
Relay types are distinguished by control signal and design. The most common are electrical or electromagnetic relays. The relay provides DC switching for a high load level, or in other words, it is a switch. Most often, the relay has five contacts, and 4-pin and 7-pin relays are no exception. All contacts in the relay are labeled, each of them has its own designation. These include a common contact, a closing contact, and a breaking contact. The relay is in a quiet state when there is no power to the coil. The coil is triggered when power is simultaneously supplied to the plus and minus contacts. A relay is an excellent “lifesaver” when installing additional equipment. An automotive relay is a special type of remote control of a switch. Using a magnetic drive, it controls electrical circuits from a distant point.
It controls electrical components such as fuel pumps, air conditioning motors and radiator fans. Relays use flexible mechanical contacts that effectively block current in the circuit they serve. Fortunately, it is easy to test a car relay and troubleshoot any problem.
Using a Relay: A relay allows you to use a small current to control a large current. Typically, the relay coil has a relatively high resistance and only requires a small electrical current to turn on the contacts. The contacts are designed to carry much more current than necessary. This means that you can use a relay if you need to make/open a path where there is relatively high current and only a small current can be supplied to the control circuit. In a car, the ignition key cannot pass a significant amount of current without being damaged. If the starter is engaged while the ignition is on, it can be instantly destroyed, so this is where a relay (also known as a solenoid) comes to the rescue. It acts as a buffer between the ignition switch and the starter. In older Ford cars, for example, the solenoid was mounted on the fender. On other vehicles the solenoid was mounted on the starter. A relay is also used to isolate two circuits. If you need to control a very high voltage circuit with a 12 volt controller, you can use a relay. Since the relay coil is generally isolated from the contacts, there is complete isolation between the "input" and "output" portions of the relay.
If the engine operates at low shaft speeds, then the voltage at the generator terminals is significantly less compared to the battery. In this case, the current that enters the parallel winding creates a very weak magnetic field, which is not enough to overcome the tension of the spring and attract the armature to the core. In this case, the contacts remain open. An increase in engine shaft speed increases the voltage at the generator terminals. If the excess voltage at the generator terminals exceeds the battery voltage, the magnetic field increases, which causes spring resistance, as a result of which the contacts can close. The entire generator load current passes through the winding, which is connected in series. When the network is powered by a generator, current flows through two windings in the direction of coincidence of the magnetic fields, which increases the force of attraction of the armature by the core. Relays are located everywhere: under the hood of the car, behind the seats, on the steering wheel, around the engine compartment and distribution block, and even in trunk. Relays act as switches that allow interruption of current to the fuel pump, radiator fan, intake throttle, air conditioning and many other circuits. They are very reliable, but continuous operation can cause their coils to break or burn out their contacts. The relay performs a common and important function during vehicle operation. The serviceability of the car relay can be checked at special terminals in a car service center.

How to start a cold engine: useful tips Video instructions with tips for car drivers in cold weather can be found in this article.
Winter brings additional problems to motorists. And they are connected not only with the need to replace tires and other things, but also with the fact that at low temperatures it becomes difficult to start your car. Show in full... The cold weather is beginning to set in and gain strength, and at the same time the number of motorists in yards and garages who are trying to revive their iron friend is increasing.
In such a situation, you need to know how to start a cold engine. At the very least, such knowledge will help save a lot of time and also save your nerves. And in the morning before the start of the working day, this is never superfluous.
Technical features
If you leave the car outside and the cold promises to be severe, then it is better to remove the battery and take it with you. You can name what you need to pay attention to first:
Before you go
Those who nevertheless studied at a driving school and remember the teachings of the teachers know what to do before driving a car. This is especially true for our domestic models, which do not have an abundance of sensors and a computer that monitors all indicators.
Check the levels of working fluids, oil, coolant in the radiator, even in the washer - these minor checks will give you the opportunity to never find out how a car radiator is repaired, and you will not be repairing the car yourself, much less find out how much a major repair costs jammed engine.

Also, look under the car more often, since most breakdowns begin with minor leaks, which an attentive owner will definitely notice in time.
Driving technique
Gear shifting and clutch operation are those nuances that are definitely worth paying attention to, since the ability to change gears in time and smoothly release the clutch greatly affects ride comfort.
VAZ 2114 clutch design
In order to notice in time that a car is behaving somehow wrong, it is not necessary to thoroughly know its design, but every driver simply must know how a car’s clutch works. VAZ cars mostly have a permanently closed clutch, which means that when you press the pedal, you release the pressure and driven discs from the frictional engagement.
Clutch pedal operation
Among the nuances of operation, it is worth noting that if the clutch is not fully released, trying to pull the car up a steep climb, it is easy to burn the friction linings on the driven disk. This will entail forced repair of the clutch unit. So if you want your clutch to work happily for a long time, try to keep it less fully depressed or released, of course, without sacrificing ride comfort.
