please, I beg you help, all my nerves are gone,

I bought the viburnum after a full inspection of everything that was possible, the brains were left, it turned out that they were flooded and completely burned in the center, I’m looking around St. Petersburg for new or used brains, but I realized that not all will fit

model 2011 8 cells 1.6 E-Gas

God bless you all, this forum is my last hope until I pour gasoline on it and set it on fire

Only family members use E-Gas. Firmware version may vary. But it should only be for E-Gas. The issue price is much less than the cost of the new Kalina. The main thing is to immediately remove the right one under the passenger’s feet and replace the heater radiator. It's very hemorrhagic there. But that is another topic. Good luck to you. It’s better to go to the specialists if you don’t want to continue to get bad impressions. For Kalina, this malfunction is unfortunately a normal occurrence if the brains are not put aside in time.

buy a disassembled kit of the entire injector system with a scythe and block, sensors, ignition switch, immobil., and a regular gas pedal. From any front-wheel drive VAZ fuel-injected car. This is a last resort option

To be honest, over 20 years, AvtoVAZ in the injector has succeeded a little in the novelty of usefulness and the old version will not be worse.

thanks for the answer, I was thinking about converting the injector to a cable but I like e-gas) and I know about the disease of viburnum with a heater radiator, but I thought this wouldn’t happen to me (thanks for the answer, if any firmware fits better, and even for e-gas I found it from trinashka, but I read the forums and they say it will still act up (

Engine control unit 11183-1411020-52 (for Kalina the last digits are -52. For Samara -02. For Grants -62). For Kalina there are several calibrations (firmwares) I444CB02, I444CC03, I444CD04, I444CE06, I444CE07, I444CE08 and I444CI07. Operation of the controller 11183-1411020-52 requires the use of a frequency mass air flow sensor 1118-1130010-00 and a new electronic throttle pipe.

buy a disassembled kit of the entire injector system with a scythe and block, sensors, ignition switch, immobil., and a regular gas pedal. From any front-wheel drive VAZ fuel-injected car. This is an option as a last resort. Honestly, over 20 years, AvtoVAZ in the injector has succeeded a little in the novelty of usefulness and the old version will not be worse.

Then it’s easier to splash gasoline.

After trying to fasten a regular gas pedal with a cable.

Currently, in cars of the Granta, Kalina-2, Priora families, control units of the ME17.9.7 BOSCH and M74 brands are used.

In 100% of cases, Prioras have a BOSCH controller programmed to control the dashboard via the CAN bus. The M74, which is now installed in Grant cars (version 11186-1411020-12), has the same property.

Speaking of the configuration with the 21127 engine, behind the glove compartment of the Kalina-2 you can find a control unit called “M74”. It should be noted that the ME17.9.7 and M74 blocks are built on different hardware platforms. In this connection, the software in them is different and incompatible, although it performs the same functions. Simply replacing the controller by installing a BOSCH unit instead of M74 (M74CAN) will not work. Improvement will be required not only at the “software” level.

Location

The ECU on the Lada Kalina is located under the center console of the car. You can see it by removing the side cover of the front passenger's footwell air duct. The block is attached to a bolted connection and securely fixed in its place. The connectors of the unit are also tightly inserted into their place and secured with a special lock, which prevents the connector from spontaneously disconnecting from the ECU.

It is quite difficult to call this location of the engine control unit successful, since it is located exactly under the heater radiator and if there are leaks in the heater radiator, the coolant gets directly onto the engine block, which causes irreversible consequences and, of course, a breakdown or short circuit.

In some cases, there is a coolant leak at the ECU, it can be repaired, but most often it is necessary to replace the unit.

Diagnosing the block

After dismantling the liquid-filled module, we inspect it. To do this, take a screwdriver with a star tip and unscrew the 4 small screws. Next, we slowly remove the control board, with which we also perform a thorough visual inspection.

The most common reason for device failure in such a situation is a burnt-out output key of the Lada Kalina ignition coil control circuit. Repair won't help here. After such a malfunction occurs, the engine begins to function on only two cylinders, and in some situations it is not able to start at all. This is where qualified service will come to the rescue. Specialists will dismantle the damaged component, wash and dry it.

The second common cause is burnout of the board itself. This fact is revealed quite simply. There will be a characteristic darkening of the surface of the board, which will eliminate all doubts.

Will repairing the ECU help in this case? The answer can only be heard in a specialized workshop. From experience, we note that the probability of help from repairs tends to zero. Will need replacement.

Sometimes there is a situation related to minor damage to the ECU circuit. In this case, the owner can get away with little expense. To “reanimate” the module, you will need to perform a number of repair procedures, namely:

• wipe the device with a dry cloth;
• apply repeated washing with WD-40 and blow with a stream of compressed air;
• rinse again, but with alcohol and also blow with an air stream;
• Dry (thoroughly) for at least 2 hours.

Some Lada Kalina owners believe that replacing the ECU is a faster and more cost-effective process compared to washing and drying. Experience has shown that the situation is the opposite. Here the determining role is given to the price factor. The new ECU will require considerable financial resources from the owner of LADA Kalina. The situation is aggravated by the undesirability of installing used “brains”. Often, a used version of the unit will be cheaper, but there is a likely risk of it not working.

What kind of ECUs are there on Kalina?

Below is a table with engine controllers that were installed on the Lada Kalina.

Installing the controller

1) For the LADA PRIORA family , attach the bracket to the controller and secure it with screws. Screw tightening torque 1.2…1.6 Nm (Phillips screwdriver, Phillips head, torque screwdriver). Install the controller on the car and secure it with nuts. The tightening torque of the nuts is 1.9…4.5 Nm (spanner 8, interchangeable head “8”, torque wrench).

For the LADA KALINA family , attach the bracket to the controller and secure it with screws. Screw tightening torque 1.2…1.6 Nm (Phillips screwdriver, Phillips head, torque screwdriver). Install the controller on the car and secure it with a screw. The tightening torque of the screw is 1.7…3.5 Nm (Phillips screwdriver, Phillips head, torque screwdriver).

For the LADA 4x4 family , install the controller on the car and secure it with nuts. The tightening torque of the nuts is 1.9…4.5 Nm (spanner “8”, interchangeable head “8”, torque wrench).

2) Connect the wiring harness connectors to the controller.

3) Install the instrument panel console screen into place (using a Phillips screwdriver). For the LADA 4x4 family, install the left front upholstery.

4) Connect the wire to the negative terminal of the battery (spanner “10”).

Why doesn't the ECU work?

ECU chip filled with antifreeze

Quite often problems occur that the engine control unit stops working; to find out the reason for the failure of the ECU, you need to inspect it:

1. Check to see if the connector has come loose from the unit; this happens quite often after installing a radio, or replacing a heater radiator, etc.
2. Check for ground on the block. Sometimes it happens that after some work, a person forgets to fasten the mass necessary for the operation of the unit.
3. Check for signs of coolant leakage on the engine block.

If such problems are not found, it is necessary to dismantle the engine block and troubleshoot, repair or replace it.

Controller functions

Location of the controller in the interior of cars of the LADA PRIОRA family: 1 - controller

The controller controls actuators such as the fuel injectors, electric throttle body, ignition coil, oxygen sensor heater, canister purge valve and various relays.

The unit controls the switching on and off of the main relay (ignition relay), through which power supply voltage from the battery is supplied to the system elements (except for the electric fuel pump, electric fan, control unit and APS status indicator). The controller turns on the main relay when the ignition is turned on. When the ignition is turned off, the controller delays turning off the main relay for the time necessary to prepare for the next turn on (completion of calculations, setting the throttle valve to the position prior to starting the engine).

When the ignition is turned on, the ECU, in addition to performing the functions mentioned above, exchanges information with the car's anti-theft system (if the immobilizer is turned on). If the exchange determines that access to the vehicle is permitted, the unit continues to perform engine control functions. Otherwise, engine operation is blocked.

The controller also performs a system diagnostic function. It detects the presence of malfunctions in system elements, turns on the alarm and stores codes in its memory that indicate the nature of the malfunction and help the mechanic carry out repairs.

During operation and maintenance of the vehicle, disassembling the controller is prohibited.

To monitor the voltage of the controller output signals, a digital voltmeter with an internal resistance of at least 10 MOhm is required.

To prevent damage to the controller when disconnecting the wire from the negative terminal of the battery or the wiring harness from the controller, the ignition must be turned off.

Replacing the ECU

Replacing the engine controller on Kalina is quite simple according to the instructions presented below.

• Remove the negative terminal from the battery;
• Unscrew the cover of the side air duct of the front passenger's feet;
• Disconnect the connectors from the controller;
• Unscrew the screw securing the ECU on the left;
• We take out the controller by pulling it towards ourselves, as if on a sled;
• Unscrew the controller from the pad;
• Installation is carried out in the reverse order;

Removing the controller

To quickly remove the electronic control unit, follow these steps:

Location of the controller in the interior of the LADA KALINA car

1. Turn off the ignition.
2. Disconnect the wire from the negative terminal of the battery (spanner “10”).
3. Unscrew the fastening screws and remove the right screen of the instrument panel console (using a Phillips screwdriver). For the LADA 4x4 family, remove the left front upholstery.
4. Disconnect the wiring harness connectors from the controller.
5. For the LADA PRIORA family , unscrew the two nuts securing the controller and remove the controller assembly with bracket from the car (wrench “8”). Unscrew the four screws and disconnect the bracket from the controller (using a Phillips screwdriver).

For the LADA KALINA family , unscrew the screw securing the controller and remove the controller assembly with bracket from the car (a Phillips screwdriver). Unscrew the four screws and disconnect the bracket from the controller (using a Phillips screwdriver).

For the LADA 4x4 family, unscrew the four nuts and remove the controller (wrench “8”).

If the controller malfunctions, a “clean” controller must be used for replacement.

Chip tuning of the multimedia system

If we talk about the firmware of all electronic systems of the Lada Kalina, then we should not forget about multimedia, which can also be subject to tuning. The Lada Kalina MMC firmware is updated to change the appearance of the menu and expand its capabilities. It differs from working with an engine in that it can be done independently at home.

In this case, you will need an SDHC memory card and special software on your computer, which must be transferred to this flash drive in unzipped form. Then, following the instructions for flashing the MMC (usually they come with the program), perform all the necessary steps in sequence.

What can be obtained as a result of modernization:

• faster responses to commands when pressing buttons, and with touch screens - clearer hits;
• installation of a Bluetooth communication system, which makes it possible to play music not only using a USB port;
• improved performance of USB storage devices—fast search and high-quality playback of recordings;
• embedding a navigation system, if one is not included in the kit. MMS Lada Kalina is adapted for navigation installation.

It is important that all changes made by software settings to the operation of the engine and MMC microcircuits can be easily canceled. To cancel engine firmware during operation, specialists save all initial parameters in a special reserve

If necessary, if the client is not satisfied with the result of the modernization, everything can be returned to its place in the same short time.

Quality assurance

The operation of the Lada Kalina engine is controlled by an on-board computer, which, in accordance with sensor readings, selects the optimal mode depending on what program is included in it. The program itself is developed by the manufacturer. In the case of Kalina, the third version of the firmware has now been released, which significantly added dynamics and reduced engine power losses during operation of the air conditioner.

However, connoisseurs prefer Lada Kalina firmware from third-party software manufacturers, the so-called Lada Kalina engine firmware. At the same time, it becomes possible to significantly improve the characteristics of the car without physically replacing parts and at the same time invest at a minimum cost.

The main difference between the tuning firmware is an increase in vehicle dynamics at low speeds, while reducing fuel consumption. This is especially noticeable when driving on the highway. In addition, chip tuning of Lada Kalina 8 valves optimizes engine performance at high speeds.

Once the Kalina 1.6 8kl firmware is installed on your car, you will be able to experience the following improvements:

• The car instantly responds to pressing the gas pedal and feels more confident at low speeds.
• The speed can be easily accelerated by jumping through gears, for example, 1-3-5 gears.
• Driving around the city can be easily done in 3rd or 4th gear.
• On the highway, fifth gear becomes relevant at not too high speeds (80 mph).
• A working air conditioner practically does not reduce engine power.
• Engine idling becomes smoother and quieter.

Today, the most current firmware can be considered chip tuning Lada Kalina 1.4 and chip tuning Lada Kalina 1.6 8kl, which most fully optimize engine performance. It is worth noting that Kalina 2 firmware will not solve all the problems of the car, especially if it is no longer new. But still, for a fairly small amount you can revive the engine of your steel friend, breathing new life into it and thoroughly adding agility.

Conclusion

As can be seen from the article, the Lada Kalina ECU is located in an accessible place. The only and serious problem remains that an accidental spill of water can lead to tragic consequences, namely the purchase of a new spare part. The cost of the part is about 4000-5000 rubles.

Everything is shown in quite detail. As a newbie in this business, everything is clear and understandable to me. Now I'll try to figure out my technique myself.

Chip tuning to reduce fuel consumption is not really chip tuning. The chip is just a chip, like a USB connection, and everything on the chip has one firmware or another. And there is no chip there, there are controllers and there is no chip there. Rewritable controllers. They chip differently. A chip is something that cannot be faked; it is something that stays with you and is not sold or distributed. The chip necessarily contains data about the owner of the car and other parameters. Give him a fulcrum and let him move this car? The chip is not a support, but it has more meaning than a support. It protects the pupil of the driver's eye.

It’s all described in a hand-cooked way. In Kalina everything is completely different. You explained the cars in the description and write that they are easy. Did the woman rewrite something for you?
