Business class cars of the 90s are very popular in the market. They cost the same as modern budget models and even cheaper, significantly surpassing them in performance. One of these models is the BMW-E34. Tuning it is discussed below.

General Features

This vehicle is the third generation german model business class 5 Series. It was in production from 1988 to 1996. During the release, the model has undergone two restyling: in 1992 and 1994. The cost of such cars starts from about 100 thousand rubles and can reach up to 1 million (for a car with low mileage). Most of the options fit into the price range from 100 to 300 thousand.

Tuning Features

The model has a sporty image, due to the settings. Such a car is usually purchased by young users, so its tuning is very widespread. On the other hand, as is clear from the cost of the car, its owners do not have extra in cash, so many of them carry out both repair and tuning of the E34 with their own hands.

In addition, it should be understood that the most common initial versions on the market are not really fast. By dynamic characteristics they are in line with modern budget models, but give that impression thanks to the settings. Really fast modifications of the M5, which are extremely difficult to find. In view of this, most modifications are very difficult to turn into sports cars. In addition, due to the weight and size, most models of this class are rarely used in motorsport, like the E34. Sometimes a car is found in drifting, and then not often. In other disciplines, there are very few such machines, as most athletes prefer the lighter and more compact 3 Series.

For the role comfortable car E34 is even less suitable to improve it in this direction, due to the tight rear seat and stiff suspension. Therefore, most often the car is turned into a fast and versatile city car.

Body

The E34 is available in sedan and station wagon body styles. The simplest way updating the appearance of the car - repainting. due to age paintwork is likely to be defective and likely to be non-original. Moreover, most cars have pockets of corrosion, if not eliminated, and other defects. All this is removed in the course of these works. You can do the tuning "BMW-E34" with your own hands by renting for this body elements(they are painted separately). All defects present are cleaned and treated with putty. Finally, having closed the unpainted fragments, a paint and varnish material is applied in two or three layers.

Body kits on such machines are rare. Usually limited to light body tuning such as replacing optics, mirrors, tinting "BMW-E34". Doing it yourself is relatively easy. New headlights should be adjusted. Tinting is usually carried out by two people. Moreover, this does not require specialized equipment, and it is quite possible to get by with improvised tools.

Engine

The car was equipped with a very wide range of engines, including 14 petrol and 3 diesel options. The most common modifications on the market are 520i and 525i with M20 and M25 engines. Chip tuning E34 pure form rarely used. This is due to the fact that only diesel engines were equipped with turbocharging, and all gasoline engines were atmospheric, and the increase in power with such a modification on them is not so great.

Traditionally, there are light improvements such as replacing the intake and exhaust. You can further improve performance by modifying the cylinder head. Very often used boring and camshafts. All these modifications are relatively simple. Further tuning, which involves intervention in the bottom of the engine or the installation of a boost, is more complicated, especially for a beginner in this business.

An exception is the installation of a compressor, which does not require intervention in the cylinder block. In this case, with a significant bore, it may need to be replaced. Chip tuning is used at the end to tune the modified E34 engine. Motor tuning is usually combined with overhaul. Before this, a person who does not have experience and knowledge should carefully study the theoretical materials or contact specialists.

Transmission

The car was equipped with four transmission options: 5-speed automatic and manual, 6-speed manual transmission and 4-speed automatic transmission. Most versions are rear-wheel drive, although there were also all-wheel drive modifications. The transmission is rarely interfered with, since standard gearboxes are characterized by good performance. Usually, only with serious tuning they increase grip, change gear ratios and differential.

Chassis

Both car suspensions are independent. Their settings are focused on handling, so the car has a sporty character. In view of this, many are satisfied with him driving performance, that's why undercarriage rarely modified. The easiest way to tune for those who lack standard handling is to install on the E34. Tuning of this type can also be done independently. It is relatively simple: the car is lifted and changed standard racks for new ones. You can change the springs and dampers separately. However, in this case, you will have to pick them up to each other, so screw suspension easier to use. You can also customize it yourself.

All versions equipped disc brakes, and starting with the 525i model - front ventilated. Their functionality is also good. Modify brake system possible, for example, by using components from more powerful versions E34 or other generations and models.

Most versions were equipped with 15-inch wheels. Naturally, all machines have custom tires, and on many - and disks. By choosing wheels according to parameters such as width, diameter, weight, profile and tire quality, you can significantly change the behavior of the car.

Interior

E34 has a very cramped cabin for this segment. Nevertheless, it has good ergonomics and high-quality materials. The level of equipment also corresponds to the business class of that time. At the same time, for the initial versions, it is traditionally very scarce. One of the most common options for modifying the E34 interior is tuning audio components. In the simplest version, many people can do such work on their own.

In addition, due to age, finishing materials may be worn out, and therefore they will need to be replaced or re-upholstered. And if it is extremely simple to replace some interior parts, then special skills are required for hauling. In addition, to carry out such tuning saloon bmw E34, requires specialized equipment.

EZ4 - legendary BMW model, mass-produced in the period 88-97. In its years, the E34 was distinguished by powerful technical specifications, comfortable interior and reference design for BMW. The car has not lost its relevance in our days - this is one of the most popular BMW versions on the secondary market, enjoying the well-deserved love of many motorists.
The legend of our time!

This article presents. We will consider chip tuning of the engine, replacement of factory components and independent modernization of the car's optics.

Chip tuning BMW E34

tuning BMW engine can be performed in two directions - mechanical or software upgrade. If you wish to old model BMW has become a car in terms of power and acceleration characteristics is not inferior to modern vehicles, we recommend combining chipovka and forcing the engine.

Mechanical modernization of diesel and gasoline engines boils down to one goal - to get the maximum possible torque and make changes to the factory gear ratios. This can be achieved in the following ways:

1. Installation sports camshaft- it will provide high valve lift, as a result of which more fuel will be supplied to the combustion chambers fuel mixture, which will increase the throttle response of the engine at low revs;
2. Replacing the standard filter with a null filter (filter zero resistance) - will reduce the loss of engine power due to air flow resistance at the inlet to the valve (gives a power increase of 3-5%);
3. Cylinder boring (requires replacement of the crank mechanism) - increases the nominal volume of the engine and maximum power;
4. By installing a turbine or compressor - due to forced air injection, the amount of fuel mixture supplied to the cylinders during the opening of the throttle valve increases, and the rate of ejection from the combustion chamber increases.

Cars everyone loves!

Upon completion of the mechanical forcing of the engine, it makes sense to resort to chipping the motor. Chip tuning for the BMW E34 consists in changing the algorithms embedded in the engine control unit by the manufacturer, in other words, flashing the "brains" of the car.

There are two ways to perform chip tuning on a BMW E34 - using a computer program to configure the factory ECU (we recommend contacting a specialized car dealership, reflashing the control unit yourself according to instructions from the Internet is a risky exercise) or purchase a ready-made modified chip and install it instead of the old one.

Petrol and diesel bmw engines E34s are chipped using different software. For gasoline engines, the Le Benzin # 1 program is used, for diesel engines - Le Digi TDI - this software is paid, there is no free access to it on the Internet.

Flashing brains increases the power of gasoline engines by 15-20 Horse power, diesel - for 20-30 horses, the following parameters are also subject to regulation:

• Maximum engine speed;
• Air discharge pressure (in the presence of a turbine);
• Ignition advance angle;
• Range of gear ratios (on automatic transmissions);
• The amount of temporary fuel injection.

Chipovka by replacing the factory ECU chip with a modified microcircuit with manufacturer-preset settings is done by hand. Chips are mainly installed on tuned BMWs V-Tech Power Box (price 250 euros), "Finnish" series boards0-261 (50 euros) andSpeed Tuning Black Storm(100 euro).

BMW is always in fashion!

Replacement of the factory chip is implemented in accordance with the following algorithm:

1. From engine compartment the factory ECU unit is dismantled;
2. The block is disassembled, removed plastic casing and remove the cap from the chip.
3. The factory board is dismantled;
4. The purchased chip is installed in the landing slot;
5. The block is assembled and installed in its original place.

For example, we give the overclocking characteristics of the 535i engine with the factory and chipped ECU firmware.

Complete replacement of the main parts (engine, body, interior, optics)

The old BMW model, along with functional tuning of the engine, also needs operational improvement. These improvements are carried out in two directions - modifying the exterior of the car (body) and altering the interior.

A powerful car should have a catchy, aggressive appearance, which can be obtained by replacing factory components with sports counterparts. Tuning spare parts for BMW E34 are presented in car dealerships in an extensive assortment, select the parts you are interested in and proceed with your own modernization of the car.

E34 is rational to start with the installation of body kits. Complete the machine with the following items:

• Side sills;
• Spoiler;
• Aerodynamic bumpers.

Confidence in the future and on the road!!!

The body kit for the BMW E34 can be purchased as a kit, which includes the above parts, or you can buy each element separately. If you want to make a car in, we recommend using computer programs for, allowing you to independently design a body kit and see how it looks on a car. With the received drawing, contact the tuning studio, where the part of interest to you will be made of fiberglass.

Alloy wheels for BMW E34 predetermine the appearance of the car. In order to improve the controllability of the machine at speed, it makes sense to install discs under low profile tires and complete them with the appropriate tires. Tuning BMW E34 525 is performed using discs sized 15*7 and offset 20 mm., bolt pattern - 5*120. To install large wheels on the BMW E34, you will need to redo the wheel arches.

The exhaust system of the BMW E34 is also subject to change. By setting exhaust pipe with double forking and a testpipe, you will get an increase in engine efficiency, due to the efficient removal of exhaust gases, and a distinctive sporty exhaust sound that draws attention to your vehicle.

The standard optics on the BMW E34 changes to xenon headlights. Xenon differs from factory optics in its powerful luminous flux and low power consumption. Headlights for BMW E34, in order to give the car an aggressive appearance, it makes sense to toned to match the body color and complete with cilia.

To complement the effect allows LED lights bottom of the car. It is carried out by means of a strip of LEDs placed in a protective plastic tube. The tube is fixed along the perimeter of the bottom of the car using drywall hangers and self-tapping screws, and is connected to the car's on-board electrical network.

Salon BMW E34 - series, last car which left the assembly line 20 years ago, requires a comprehensive rework. It is rational to start BMW E34 with factory upholstery on the ceiling, floor and car seats.

For tightening, we recommend using genuine leather - you will spend a large amount on the purchase of material, in comparison with artificial substitutes, but subsequently deprive yourself of the need to re-tighten, since the skin is highly wear-resistant, and aesthetically attractive leather interior on high.

Be the center of attention!

Performing tuning Salon BMW E34 combine leather upholstery with carbon look on dash and dashboard. Vinyl, in addition to the decorative component, protects plastic surfaces from scratches and mechanical damage.

Tuning the BMW interior, if a power increase was previously performed power unit must be accompanied by soundproofing. You will need a compartment on the engine side with the use of a vibration-insulating material with a foil layer (Vibroplast, Bimast) and a polyurethane sound insulator (Shumoff, Splen).

Upgrading the motor requires replacing the factory brakes with reinforced ones - this is a safety issue that cannot be compromised. We recommend using ATE Power Disc ventilated discs, the cost of such a spare part for a BMW E34 is $ 400 (for full set), but the efficiency and durability of these discs justifies every ruble spent on them.

Self tuning optics

We bring to your attention instructions for converting the headlights into optics stylized as Hella Black headlights, the cost of which is $ 600.

You will need:

• sealant;
• Black matte paint;
• Sheet aluminum 1 mm thick;
• Building hair dryer and tools for dismantling headlights.

The sequence of actions is as follows:

1. We dismantle the front optics of the high and low beam, remove the chrome rings from the headlights;
2. We heat it with a hairdryer (temperature 600 degrees) until the sealant melts, pry the glasses with a sharp object and take them out;
3. We print a blank for crosses on the printer, apply paper to sheet metal and cut out the details along the contour;
4. We paint blanks, chrome rings and headlight reflectors with black matte paint;
5. We assemble the headlights, for sealant (we recommend using a black composition);

As a result of several hours of work, you will receive optics that are visually indistinguishable from the original $500 headlights.

tuning rear lights do-it-yourself, aimed at darkening the optics, thanks to rectangular shape lanterns can be done by tinting film. Tinting requires the preliminary dismantling of the optics from the car.

You will need materials:

• tint film;
• Building hair dryer;
• Soft rubber spatula;
• soap solution;
• Stationery knife.

WATCH THE VIDEO INSTRUCTIONS

Taillight tuning is performed according to the following algorithm:

1. from the car, clean and degrease the surface, wait for drying;
2. We apply the film to the optics and mark the workpiece along the contour of the headlights with a marker with a margin of 2-3 cm on each side;
3. Cut the film to size
4. We spray a soapy solution on the surface of the headlight, remove it from the film protective layer and attach the workpiece to the optics. With a rubber spatula we expel water from under the material (movements from the center to the edges);
5. To smooth out the wrinkles that have arisen, we heat the surface of the film with building glue and straighten the irregularities with a spatula;
6. The edges of the film are wrapped on the side ends of the headlights, leveled and cut off along the extreme contour;
7. Tinted lights are kept for 4-5 hours at room temperature and installed on the car.

Do you know how popular german car produced from 1987 to 1996? BMW E34 - the model can be called a classic German car industry. How do you turn a classic into a modern car? Of course, with the help of tuning. Therefore, the topic of our publication is BMW tuning E34.

We will not dwell on the options for external and internal tuning- there are a lot of them. We still can’t describe everything, and it makes no sense. Here you need imagination, and there are many tools on the market to make it a reality.

The article will touch upon the tuning of the main BMW unit E34 - engine. So, today you will learn:

• several ways to increase the power of the motor;
• chip tuning programs recommended by German specialists, with a brief description.

How to increase power

To increase engine power, you will need to increase the torque and change the gear ratios in the transmission.

1. If the engine is not turbocharged, then there are two ways to achieve the described result:

a) Replace the factory crankshaft with a similar one, but with an increased eccentricity (degree of deviation from the circle).

Firstly, crankshafts with an increased degree of deviation for the BMW E34 are not mass-produced - you will have to look for companies that manufacture shafts to order. You understand that things to order are much more expensive.

Problem #3 is the need to install shorter cranks. This is not advisable for two reasons:

• they are less durable;
• their installation leads to an increase in mechanical losses, and hence to a decrease in efficiency.

b) Bore the cylinders in order to increase their diameter, respectively, and volume.

Naturally, in this case, one cannot do without replacing the entire cylinder-piston group. But it is much easier - it is enough to purchase a crankshaft with piston diameters that will be equal to the diameter of the bored cylinders.

2. If your BMW E34 is equipped with a turbocharged engine, then it is better to resort to flashing the ECU to increase power.

Below you will learn about two programs developed by BMW specifically for the E34. They can be used on both turbine and atmospheric engines.

Chip tuning BMW E34 - LE BENZIN1

Designed for models marked i:

• 518 - power increases by 10 hp
• 520 - 15 hp
• 525 without Vanos(variable valve timing system) - 15 hp
• 525 with Vanos- 16 hp
• 535 - from 211 hp increases to 231 hp
• 540 - 18 hp

Chip tuning BMW E34 - LE DIGI-TDI

Designed for diesel units:

• 524TD- power increases by 24 hp, torque - by 42 units, speed - by 13 units.
• 525TD- everything is similar to the previous option, only the speed will increase by 10 units.
• 525 TDS- by 27 hp, torque - by 70 units, speed - by 8 units.

You can buy such programs in online stores. If you can’t find it in local, look in German - in this case, the cost of delivery will need to be added to the existing cost.

On this, let me bow and go in search of other materials of interest to you.
