Chip tuning ME17.9.7 without opening (Priora, Kalina, Niva, UAZ) Suvorov (Tula, Kaluga)

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.

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.

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 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.

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.

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.

Brother Priora has it. 2010 M7.9.7+ V174DT05. Full luxury. Ran 3000 km. Passed 1 MOT. There are no comments on the car. Now we want to upload some commercial firmware. Requirements: 1. To be as insensitive as possible to the inclusion of the air conditioner and be normally adapted to it (timely switching on of two fans, probably slightly increased idle speed, so that they do not float under load, well, etc.) 2. I would like to get maximum power from the engine from bottom to top, because brother is a racing enthusiast. 3. I understand that the consumption will be greatly increased during extreme driving, but what will it be like with a normal calm driving style? Much more than the factory one? 4. We are not going to remove the catalytic collector, I don’t think we will gain much from this in power, and in general we won’t interfere with the engine and gearbox. We don’t need any increased throttles either. As it was from the factory, let it remain so, so that when for maintenance drive, you could download the serial program and calmly undergo maintenance.

Firmware order:

1. Copy the firmware files (Chain.bin, chain.lst, NK.bin, TINYNK.bin) to the root of the SD card.
2. Remove the flash drive from the USB port.
3. Insert the SD card into the MMC.
4. Restart the radio (for Lada Kalina 2/Priora - hold down the power button for 15 seconds, for Lada Granta hold down the volume button for 15 seconds).
5. During the download, an update will occur, after which the radio will boot into desktop mode.
6. Without rebooting the radio, go to the screen calibration mode (Start/Settings/Control Panel/Stilus/ to the Calibration/Recalibrate tab), then press the screen during the countdown.
7. Reboot the MMS with the SD card inserted.
8. The firmware of the radio is complete, the SD card can be removed.

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.

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.

For this we need:

Universal adapter KL-Line BM9213 USB MASTER KIT for tuning a car with an injection engine, you will not chip the carburetor with it,

You can read more about it and how to purchase it here. For the adapter you will need a virtual COM port driver for Win XP, Vista can be downloaded here, you can also use another adapter VAG COM USB KKL v409.1 which you can buy from our partners, this is the same KK-Line adapter only in a housing and for ridiculous money.

Next, to flash the chip firmware, we will need ChipLoader 1.96, you can also use the newer version of ChipLoader 1.97.7, but the previous one also works stably, so I don’t see the need to use the new one.

in the Help > Help tab you will find the User Guide, also go to the settings and uncheck all the boxes as shown in the figure above. In order for the block to start sewing, it needs to be modified according to the instructions in the User's Manual, everything is described in detail there.

You will also need firmware, if you just want to try chipping, then first you can try the free Tuned VAZ firmware, but I would advise you to immediately flash the normal VAZ Commercial firmware, the difference is significant.

Also, many beginners wonder why ChipLoader gives an error after selecting a 260 kB firmware?

The answer is simple, ChipLoader supports firmware only in full-size format, i.e. “Decrypt” size is 832 KB (851,968 bytes) to decrypt the firmware we need the SMS Enigma new v 1.10 program

First, you need to remove the ECU to read the inscription on the sticker, then you need to determine its type, you can do this here, my sticker looked like this:

I have identified my unit as Bosch 7.9.7+; in order to program it, it needs to be modified; it is written how to do this here

Next we need to assemble a simple circuit, I made it simply from thick wires so that they could fit onto the ECU pins.

I took the 12 volt power supply from 8 1.5V batteries, you can use a power supply, but only a stabilized one, do not use pulsed ones from the computer from the one from which you will be sewing, units from Sega Dandy consoles and other Chinese equipment are not suitable, it is better to take power from batteries straight from the car, and sew on a laptop without connecting to the network, or use an uninterruptible power supply in case the power suddenly goes out
