What firmware to install on Priora 16 valves

Chip tuning of Lada Priora is a change in the software (chip, firmware) of the electronic engine control unit to increase power, reduce fuel consumption, eliminate failures, and ensure stable operation of the engine control system.

Lada Priora cars with control units M73, M74, Bosch 7.9.7 and Bosch 17.9.7 are available for flashing. For tuning we use software from leading Russian developers: Paulus chip, ADACT, Ledokol.

The proposed chip tuning software is intended for use on ordinary (non-sports) cars without the goal of obtaining maximum power and torque, without reducing the service life of the units.

You'll get a well-balanced increase in power and torque not only at high rpm under full load, but also in the low and mid-range, without increasing emissions.

After installing the modified software, improved driving characteristics can satisfy even the most demanding car owners.

The firmware is focused on comfort in driving: elimination of factory software errors, elasticity, reliable starting at any temperature, no dips and twitching, freezing of speed, elimination of sluggish acceleration dynamics, excessive fuel consumption. When the air conditioner is turned on, the loss of engine power is significantly reduced.

In addition, it is possible to eliminate errors due to non-functioning oxygen sensors (lambda probe), remove the software catalytic converter (catalyst), and also reflash the Lada Priora to Euro 2 or Euro 0.

The appearance of error codes P0130, P0131, P0132, P0133, P0134 and other errors associated with a faulty lambda probe, catalyst errors P0420, P0421, 0422, P0423, P0124, P0430 can be eliminated forever with the help of reprogramming and without compromising the driving characteristics of components and units. The warranty for the operation of the modified software extends to the entire service life of the vehicle, that is, indefinitely. Working time 1 hour. For each car, a certificate is issued with a unique authentication code, which can be verified on the software developer’s website.

In addition, for the Lada Priora it is possible to disable any errors, remove the adsorber, remove the immobilizer, adjust the temperature of the fan, disable misfires, disable the brake and clutch pedal sensors, adjust the idle speed, change the cut-off speed, disable the rough road sensors, the camshaft sensor.

Chip tuning of Lada Priora – is it worth doing?

Lada Priora is a worthy representative of the Russian automobile industry. It is on a par with foreign-made “classmates”, but compares favorably with them due to its attractive price. The operation of the Priora engine is controlled by an on-board computer, or ECU. He manages the fuel supply system and ensures the synchronous operation of all units.

Every car has hidden capabilities. Chip tuning allows you to take advantage of this potential. Reprogramming is carried out through the OBD diagnostic port. By adjusting the engine control program, you can change the air-fuel mixture supply mode, ignition timing and other engine operating characteristics.

What is an electronic control unit (ECU) chip?

Everyone knows that chip in translation means “slice”. It is no less widely known that electronic chips are information storage facilities for computer systems. Likewise in a car, a chip is a microcircuit that contains the “firmware”, “operating system” of the ECU.

How does this happen

This system is based on reading sensor readings. Schematically, the principle of operation of an engine with an ECM (Electronic Engine Control System) looks like this.

1. Signal receipt from various sensors.
2. Processing of received data in a microcircuit, chip, ECU.
3. Switching on of actuators according to the provided tables.

The operation of the sensors is based on various principles, but the essence is the same, a change in voltage during any action. Thus, the crankshaft position sensor changes the voltage at the moment when a gap appears in front of it in the toothed rim of the pulley. A change in voltage at this moment lets the computer know that the crankshaft is rotating and it’s time to supply a spark and fuel. The throttle position sensor (TPS) shows the degree of throttle opening by changing the resistance. In this case, the ECU, in accordance with the attached tables, regulates the opening time of the injectors. That is, it increases or decreases the fuel supply. All this is done by the same Chip.

The first cars with an ECM and replacing their firmware

At first, the USSR auto industry collaborated with the American one. This was in the 80s. The ECUs installed on the first versions of “injection” cars were of the corresponding brand - GM. Then a domestic analogue was created - “January 4”. In general, the order of release of ECUs with firmware for domestic cars was as follows.

• GM VAZ (January 4th analogue)
• Bosch 1.5.4 (January 5.1)
• Bosch 7.9.7 (January 7.2, M73 Euro3)
• Bosch 17.9.7 (M74) Euro-4, E-gas.

A little about firmware

If you still decide to upgrade the ECU yourself, use only high-quality firmware. According to reviews from car enthusiasts, Paulus firmware is a good option, as they “correctly” change the settings of the electronic unit. Moreover, they should be downloaded from official sites, and not from third parties. Because you can run into a fake and spoil the characteristics of the car.

Therefore, be extremely careful when choosing new software, since the cost of an error is very high and there is a risk of damaging your car with low-quality software.

How to flash Bosch ECU 7.9.7+

Here I will tell you how you can flash the ECU of a VAZ 21703 Lada Priora, since I myself decided not to pay anyone money and do it myself, everything worked out and works great, and those who say and scare you that nothing will work out for you simply they want to get money out of you!

I won’t lie, you will still have to spend around 1000 rubles. to purchase an adapter and firmware, but it’s worth it, after that you can upload any firmware to your taste and do it to your friends for a small fee and get the money back, and drink beer.

How to do chip tuning yourself

As already mentioned, the best option for tuning is to contact a car service center. There, specialists will be able to accurately change important settings of your ECU without damaging the operation of other vehicle systems.

Flashing the VAZ 2114 ECU

If you really want, you can try to flash the firmware yourself - to do this you will need to connect the PC to the ECU via a programmer and set the required settings in the working window of the screen (on different machines, electronic units can be programmed using different programs, each of which has its own operating features; according to For this reason, it won’t be possible to give any specific advice here on how to flash a VAZ 2114 step by step).

The only thing you should remember when performing independent chip tuning is the relationship between all operating parameters of the engine. So, by increasing its power to the maximum possible value, we will get a significant increase in fuel consumption, and along with it - increased toxicity.

It should be said once again that if you are completely ignorant of programming and have only basic PC knowledge, then doing chip tuning yourself is absolutely not worth it. After all, the result obtained can be not only zero, but also negative.

Rules for handling the motor after flashing

Chip tuning, carried out by a highly qualified specialist, really improves the performance of a naturally aspirated engine: it increases its power, increases throttle response, which is especially important in overtaking mode, and reduces fuel consumption. When overtaking, the maneuver time is reduced, you have to press the gas pedal less when driving without acceleration, and change gear less often when using a manual transmission. Otherwise, driving a chip-tuned car is no different from driving a regular car.

Individual modification of the engine, performed professionally and using modern equipment, has a positive effect on the functioning of the engine. Chip tuning allows you to make the operation of the power unit more flexible and dynamic. At the same time, it is also necessary to take into account the negative consequences of such alterations: the service life of the catalyst is significantly reduced and the engine service life is reduced.

• Engine protection on Priora
• Installation: additional door seals Priora
• Installing an air conditioner on a Lada Priora
• New firmware for VAZ 2114
• Wheel rims for Lada Priora

Main stages of chip tuning

Before you begin upgrading the engine, you must bring it into a condition that meets factory specifications. Otherwise, the cost of chip tuning and the setup itself will be pointless. The reprogramming procedure does not depend on the make of the car or the number of camshafts with 8-valve or 16-valve mechanisms. Chip tuning of the Priora engine consists of four stages:

1. Reading the standard program in the ECU - this procedure is carried out through the OBD diagnostic connector.
2. Editing a downloaded program.
3. Uploading the edited, firmware program back to the controller.
4. Checking the operation of all vehicle components on a special stand equipped with instrumentation and mechanical rollers, or in the field.

If the program needs to be modified, it is adjusted and uploaded back to the ECU. The described procedure is repeated until the desired result is achieved. You can do the firmware of the program yourself if you have knowledge in the field of computer programming and special equipment.

Tuning package STAGE-2 for 16V VAZ 2110-2112, Kalina, Priora

Tuning package Stage-2

will noticeably change the character and behavior of your car.
The result of installing this kit will be an increase in power by 30-35%
with minimal intervention in the engine itself, which will not affect its service life in any way. The advantage of such a modification is a tangible improvement in the dynamic characteristics of the car while maintaining its factory integrity.

The main elements used in the modification are camshafts with a modified cam profile, a modified intake receiver and a tuned exhaust system. Increasing cylinder filling is achieved by increasing valve lift and reducing intake resistance. Also, the correct exhaust for rapid removal of exhaust gases is also important. The included fully direct-flow Stinger exhaust system provides excellent cylinder cleaning and a thoroughbred, sporty sound. The muffler used in its composition without an attachment has a low noise level, which will not cause inconvenience to either you or your downstream neighbors.

Once the installation of all components of the package is complete, the engine control unit is configured online.

What is included in the Stage-2 tuning package:

1. Camshafts “TEAM80” or “STI”;

2. Camshaft pulleys are adjustable;

4. Throttle pipe 54 mm;

5. Direct-flow exhaust system “STINGER” (4-2-1 manifold, resonator, muffler without nozzle);

6. Gaskets and fasteners necessary for installation of the above parts;

8. Programmable controller (used);

9. Configuring the engine control unit in real time via ShDC (Online).

The Stage-2 tuning package is used for the following cars:

VAZ 2110, 2111, 2112, VAZ 1117, 1118, 1119 (Lada-Kalina), VAZ 2170, 2171, 2172 (Lada-Priora) with a 16-valve engine with a mechanical accelerator drive.

It is also possible to use the package for 16-valve cars VAZ 2108, 2109, 21099, VAZ 2113, 2114, 2115, but with an increase in cost. This is due to the need to modify the radiator frame, which prevents installation of the receiver, or to install a more expensive receiver that does not require modification of the frame.

3 A little about the benefits of tuning for the Lada Priora

With the help of tuning, as already mentioned, you can improve a number of indicators of the Lada Priora, among them:

• Engine starting is easier even at very low temperatures;
• Driving a car on different types of roads becomes more comfortable and easier;
• A noticeable reduction in vehicle fuel consumption (by 5–15%);
• Improving the quality of acceleration dynamics and increasing the power of a gasoline engine by 8–12%.

The factory firmware of the Priors lacks some qualities or is mutually exclusive. A unique do-it-yourself setting allows you to achieve the desired desired result. If the chip contains a fresh program, then accordingly more algorithms for interacting engine characteristics appear. For example, while driving, it becomes possible to switch control modes, that is, use a propulsion system with the characteristics of a sports mode or an economy mode.

Competent tuning of a Lada car requires choosing the right program that will most accurately reflect the owner’s wishes for improvements and suit the engine system. The consequences of pumping the control unit through the chip largely depend on the quality of the firmware and the professionalism of the setup by a specialist.

What is firmware for Euro 2?

Euro toxicity standards were introduced more than 30 years ago, back in 1988. The regulation controls the requirements for the amount of carbon monoxide, nitrogen and other toxic substances emitted by cars into the atmosphere.

The composition and level of harmful components that make up the exhaust are controlled by law. Driving in cars where these requirements are not met is prohibited.

The original standard was called Euro 0. Every few years, the requirements become stricter and the regulations are adjusted. Today, in 2020, Euro 6 is already in force in the European Union. Our country lags behind Europe by 5-7 years, and therefore, for now, requires cars to comply with the Euro 5 class.

This means that it is impossible to introduce a car with a lower eco-standard into our country. Likewise, selling it abroad will also not work. However, if you once managed to enter and register such a car, you can drive without any problems. Also, you can “roll back” to the Euro 2 firmware; the documents will still show the version assigned to the car upon initial import.

What does firmware for Euro 2 provide, besides the obvious increase in the amount of toxic emissions into the environment? Why harm nature, contribute to the daily gray smog over megacities and the unpredictable process of global warming?

Below we will definitely present the pros and cons of Euro 2 firmware, and now we will announce some numbers. The limit values ​​of exhaust pollutants for Euro 5 are as follows:

• 0.05 g/km to hydrocarbons;
• 0.8 g/km to carbon dioxide;
• 0.06 g/km to nitrogen oxides;
• 5 mg/km to particulate emissions.

Now look at the Euro 2 emissions standards:

• 0.29 g/km to hydrocarbons (almost 6 times higher);
• 2.2 g/km to carbon dioxide (almost 3 times higher);
• There are generally no standards for nitric oxide;
• 70% higher than the fifth environmental class.

Gasoline and diesel engines pollute the environment, this is an indisputable fact.

8. The firmware of the radio is complete, the SD card can be removed.

Engine Features 126

The development of the 21126 internal combustion engine was carried out in parallel with the VAZ-21124 internal combustion engine. With different working volumes of the models, a large number of coincidences were noted for the incoming systems and nodes. The main task before the creators of the 21126 engine was to obtain the most durable mechanism, characterized by a long service life.

The elements of the connecting rod and piston group were developed by Federal Mogul. The company's engineering team created a design that compares favorably in weight (30% lighter) with a similar kit installed on the 2110 machine.

In terms of external parameters, the engines of variants 124 and 126 are very similar, but there are certain differences between them. What is the difference between a 124 engine and a 126:

Reviews about chip tuning VAZ (LADA) Priora

Do you also have something to say?

The salary arrived and what did you do right away? Of course I got it! The car has become like another) It drives differently, more dynamically. The traction is very good from the bottom. Pickup from 3000 thousand/rev is instantaneous. And up to 3000 thousand/rpm it runs smoothly and pulls well. Consumption should decrease. But I haven't measured it yet. The cutoff was shifted to something like 7000. The catalyst was turned off. While the firmware is being rolled out. We sewed it with ADACT firmware for 95 gasoline. It is more dynamic than the 92 and the consumption should be even less))

I sewed a Priorica 16kl with a replacement ecu for January 7.2. This is where it got really cool. I took measurements at 9.6s and it was 11.2s. I went with a sports grant to the body and left her, that’s basically all. As for the specialist, I can say that he is a professional in his field. Anyone from Bryansk, guys, go to Alexander for firmware, you won’t regret it, it’s worth the money and you will enjoy further use.

The word “chip” has long been firmly established in the colloquial speech of our motorists. However, few people know what this process is in reality. Why is it called that, and is it worth doing it on your car? In particular, at Priora. Therefore, it is worth explaining this issue in detail. With a short excursion into the history of “injection” cars.

Modern methods of ECU firmware and equipment for this

After this, Bosch again took a step towards simplification. The new Bosch 7.9.7 block is already flashed by removing just one microresistance. Well, Russian developers have again created a good analogue (January 7.2), which in general can be stitched without “surgical intervention”. And then M73 for Priora. But it already contains the firmware. Same resistance as Bosch. However, it is just as easily removable.

What equipment is used to change the Priora firmware?

There are now many devices on sale that are designed to connect an ECU with a personal computer. These are adapters that transcode data from the “brains” of the Priora into an understandable PC interface. The most popular devices are the following.

• Adapter from Scanmatic.
• Block programmers from NPP NTS.
• Firmware downloaders from SMS.

All of them come with instructions for use and a set of cords with connectors for connecting to different computers.

Firmware

Only a programmer who has full knowledge of the structure of a car with an ECM can create firmware for the Priora ECU from scratch. Therefore, all auto electricians involved in chip tuning use ready-made modules. You can find them on specialized websites and download from there.

Firmware classification

The programs installed on the Priora computer are quite unified. That is, the middle option in the sets of tables for engine operation was selected. And buyers have different driving styles. They have their own ideas about fuel economy and other parameters. Conventionally, types of firmware can be divided into three categories.

The features of these programs can be determined by their name. Moreover, each of the categories also has dozens of different modifications, and are selected individually for each driver. By the way, it is possible to install two options simultaneously on one Priora, with a switch button.

The Economy category also includes firmware adapted for gas equipment, which has become popular recently.

Firmware of the first samples

What makes owners change, do chip tuning, “Priors”? Since the mid-2000s, the Euro-3 standard has been firmly established in production. This is a dual oxygen sensor system. The second one is located after the exhaust catalyst, or particulate filter. The thing is that due to the quality of the fuel, this sensor and the catalyst itself often fail. The control unit reacts to this by sharply reducing the fuel supply. Driving turns into sheer torture. And replacing them is expensive. Therefore, the main goal of Priora chip tuning is to install firmware with Euro-2 parameters.

Tuning the Priora 126 engine for 20-30 thousand rubles

In the comments they asked a question about Priora. What can be done for 20-30 thousand rubles. with a motor to make it go better.

Let's first consider the situation for 30,000, and then the minimum for 20,000.

For 30,000 you can bore the channels, throw in the shafts , change the throttle valve, injectors and calibrate the engine.
Now let’s look at how much each position costs. First, let's go over the material. 16-valve shafts cost from 6500 and above. I would eventually install some turbo shafts. Because the engine will spin no more than 7000, the engine is quite low and in the future it will seem to you that the increase is not enough, you will get tuning disease and will continue to charge the engine. In order to have the most important foundation for development, you buy turbo shafts, say 9.6, and 10.1 for the intake and exhaust. In principle, a small overlap is very good for a low-end motor. They cost approximately 6800 from the manufacturer. By the exhaust. Install a spider that simply replaces the catalyst. It costs around 1500 rubles. Source
