Which Ecu Is Better Bosch Or January

All three ECUs of this table are Euro II systems, with DC, adsorber and phase sensor (or camshaft sensor) and are completely interchangeable with each other.

Within this group, there is an ECM under the toxicity standards of Russia. 83, without DC and adsorber. January 5. 1. 2 1411020. 71

Your options for the mutual replacement of the computer are presented from the position of the manufacturer.

From the perspective of software and tuning (chip tuning), the possibility of replacement is somewhat wider. But there are corresponding limitations. Consider the options for interchangeability on the example of the most common type. January 5.x.x. The interchangeability of the ECU "VS" and "Bosch M 1. 5. 4" is made according to a similar algorithm.

All ECUs (inside their type) are built on a single platform and differ mainly in the switching of nozzles and a heater of a recreation center. For example:

January 5. 1 2112. 1411020. 41. phased injection, oxygen sensor
January 5. 1 2111. 1411020. 61. in pairs. parallel injection, oxygen sensor

These two modifications are completely identical in hardware, they differ only in firmware, which means that, for example, having written firmware from 2111. 61 in blocks 2112. 41, it can be installed instead of 2111. 61 and vice versa. Further:

January 5. 1. 2 2112. 1411020. 71. phased injection, without oxygen sensor

This modification is distinguished by the absence of DC control elements on the base board and cannot be installed instead of 2112. 41 or 2112. 61 blocks (or rather, it can, but with the condition of disconnecting the DC), but 2112. 41 or 2111. 61 blocks will work fine instead of 2112. 71 with the appropriate software (2112. 71), with one caveat: harnesses for 2112. 1411020. 71 different years of manufacture may vary. Rather, there are “new” harnesses in which the 1st nozzle (pin 23) is connected to the recirculation valve (pin 17) in the connector and then goes to the 1st nozzle. As a result, when the ignition is turned on, the 1st nozzle is constantly open. When replacing, it is necessary to check this circuit and if it is present, break it.

January 5. 1. 1 2111. 1411020. 71. simultaneous injection, without oxygen sensor

This modification has hardware differences, although a craftsman with a soldering iron in his hands can quite easily, by adding the missing chips to the block, turn January 5. 1. 1 (or 5. 1. 2) into January 5. 1. In January 5. 1. 1 there is not enough pair of microcircuits, one of which is a nozzle driver, the second works with an adsorber, a recirculation valve and the length of the exhaust pipe. Injectors in January 5. 1. 1 (as in any other simultaneous injection system) are controlled through (!) The channel of the oxygen sensor heater. This means that any unit with DC support (2112. 41 or 2111. 61) with software for 5. 1. 1. 71 will work in place 5. 1. 1. 71. From January 5. 1. 2 there is no such compatibility , because in this ECU there are no controls for the heater of the DC used in the simultaneous injection of 5. 1. 1. 71 as a nozzle driver.

Naturally, the software of the unit should correspond to the type of injection and the wiring used.

In fact, on the car, you can install any unit with a wiring alteration corresponding to this unit or its replacement and the corresponding software. But you need to remember one caveat. ECUs differ in different drivers on the DPKV channel, they can have different requirements for the signal polarity of this sensor. Therefore, if, for example, Bosch M 1. 5. 4 refuses to start instead of January 5. 1. you just need to swap the wires suitable for the DPKV.

It should be borne in mind that 2112. 41 and 2112. 71 units with the same marking can have hardware differences. It is very simple to distinguish them. a new hardware implementation leaves the factory with software of the “J” series (or newer). These block options are distinguished by the injector driver chip used. In the old block is SIEMES TLE 5216, in the new. MOTOROLA MC 33385. They differ (among other things) and the diagram of reading driver diagnostics. Therefore, on new blocks with old software or vice versa, driver diagnostics errors may occur, for example, the notorious break of the 3rd nozzle.

Among other things, in connection with the discontinuation of the HIP 9010 chip (detonation channel processor), since 2006, computers supplied with spare parts have installed HIP 9011, which differs in the SPI programming procedure, and, of course, the software that can be easily distinguished by marking is changed Software. the use of the letter A instead of J in the name of the firmware. For example, A 5 V 05 N 35. The "old" firmware in such ECUs "do not see" detonation and can be applied only after a small software editing special utility from SMS. Software.

Bosch

Inside the Bosch M group 1. 5. 4 2112. 1411020. 40 and 2111. 1411020. 60 are completely identical and interchangeable, the only difference is in the software.

But the ECU for simultaneous injection (2111. 1411020. 70) has a hardware difference in the control circuit of the heater (40th and 60th blocks), which is used as a nozzle driver in the 70th block, a diode is installed that keeps the nozzles in open state more Estimated time and two zener diodes are missing. That is, in this case, the diode need to remove and solder the two missing zener diodes. Naturally, this applies only to the case when Bosch. 40 (60) is installed instead of. 70 with the corresponding firmware. (Respect to Sergey Peretokin, who understood this problem and sent this material and scheme.)

VS 5. 1

ECU VS 5. 1 manufactured by Itelma is functionally analogous to January 5, that is, it performs the same functions, is compatible with wiring (that is, for example, VS 5. 1 with firmware V 5 V 05 N 35 can be installed instead of any January 5. 1 2112. 1411020. 41 or instead of Bosch M 1. 5. 4 2112. 1411020. 40).

These ECUs are also found with various hardware implementation. In 2003, NPO Itelma completely modified its lineup. But, unlike other systems, software for "new" and "old" blocks completely incompatible, that is, the "new" software only works in the new block, the "old" only in the old ones. The algorithms and approach in terms of chip tuning is completely similar January 5.x.x

"New" modification VS 5. 1 1411020. 72 (simultaneous injection) with firmware V 5 V 13 K 03 installed on the VAZ conveyor since September 2003. This software is incompatible with earlier versions (V 5 V 13 I 02, V 5 V 13 J 02).

"New" modification VS 5. 1 1411020. 62 (pairwise-parallel injection) with firmware V 5 V 13 L 25 has been installed on the VAZ conveyor since December 2003. This software is not compatible with earlier versions (V 5 V 13 K 22).

"New" modification VS 5. 1 1411020. 42 (phased injection) with firmware V 5 V 05 M 30 installed on the VAZ conveyor since December 2003. This software is not compatible with earlier versions (V 5 V 05 K 17, V 5 V 05 L 19).

That is, roughly, there are two groups of blocks. Based on the ID of the firmware indicated on the nameplate and / or the date of manufacture of the unit, it is easy to understand that there “flash”

© SPY. The compatibility of these blocks is how confusing, let’s try to figure this out thoroughly.

On all controllers of the new hardware implementation, the nozzle control is output to the usual outputs of the controller for Euro-2 (pairwise parallel and phased injection), that is, 16, 23, 34 and 35.

This is true for the controllers. 42. 62 (- 72!), But the controller. 72 differs from. 42 and. 62 in the absence of a key that controls the heater DC (marked with a “2” in the photo) and the presence of four jumpers installed in places marked with a number “1”, that is, he has outputs to the nozzles except for those described above, also at pins 15 and 33, respectively, in pairwise connection.

In other words, the controllers are completely interchangeable despite the installed software with some clarifications. The controller. 72 with the program V 5 V 13 L 05, for example, will work on the machine on which the controller. 41. 61. 71 stood before without altering the wiring, but. a controller, for example. 42 with the V 5 V 05 L 05 program embedded in it will work in a car where the controller previously stood with simultaneous injection in the case of installing four jumpers and removing the DK heater key, or without alterations completely instead of. 41. 61. 42. 62.

Example: The controller is 72, the M 30 program with the DF turned off (although you can turn off only the DF health check) and the DK turned off as you perverted :)) will work absolutely on any VAZ model, except for MP 7 and Bosch 797.

Another example: Controller. 72, program L 05, will work everywhere without reworking wiring.

Another example: Controller. 42, program L 05, will work instead of. 72 if you solder the heating key for the recreation center (2 in the photo) (although you can not solder it, just cut the track from the key to the terminals of the computer) and solder the four jumpers (1 on the picture) …

Quite a wild example: Controller. 72, program M 30 or L 25 with the DK heater working condition control disabled and the extended time allotted for the readiness of the DK (the heater does not heat up), turn off errors about the DK malfunction, it will work on the wiring (configuration) Euro– 2, only the exhaust gases will not be sensed very soon until the DC is heated by the exhaust gases. (the author checked the last example for a long time, since then they may not solder parts through the channel of the DC)

BOSCH MP 7. 0 H

The topic of replacing MP 7. 0 blocks with January, Bosch or VS is quite popular right now. Such a replacement requires re-crossing (re-switching) of the wiring. Naturally, since the wiring needs to be redone, you can decide for yourself what type of injection you will do it for.

Crossing options you can see here and here.

Crossover as a tuning method is primarily associated with the complexity of understanding and tuning the software algorithms of these systems, but the situation is gradually improving :). This type of computer is the most “sparing” for the user. There are frequent cases when the system maintained a satisfactory condition in the event of a malfunction of half the sensors.

Blocks MP 7 are almost identical to each other, but there are options for Euro-III, which supports the management of two heaters. Accordingly, in Euro-II systems, these elements are simply not soldered.

Bosch M 7. 9.7

As mentioned above. Bosch M 7. 9. 7 was installed in series on a part of the engines of the "tenth" family of 1.5 liters. and is installed on 1, 6 liters. in the configurations 8 V (21114) and 16 V (21124), Guelder-rose 1, 6 8 V (11183) and on the Niva-Chevrolet 1, 7 l. 8 V (21214). All systems meet the requirements of Euro 2 / Euro 3, all with phased injection. Structurally, the computer is made for a different type of wiring, has an 81-pin connector.

The software for this ECM was developed by BOSCH specialists with further adaptation by VAZ specialists. The software of this ECU is an engine model with a minimum set of “external” calibrations. At present, there are no opportunities to control the complete set and self-training of the unit. But work is underway in this direction and the chip. tuning of these systems can already be done quite successfully using software from SMS-Software.

Since August 2005, a new hardware implementation of these blocks has appeared, without an external flash, with memory built into the processor (symbol M 7. 9. 7). The old and new type ECUs are fully interchangeable functionally. But the firmware for the "old" and "new" implementations are incompatible and non-interchangeable, because they are designed for different types of processors. The firmware even has a different size. 512 K for M 7. 9. 7 and 832 K for M 7. 9. 7

January 7. 2

January 7. 2 ECU structurally executed on a different type of wiring, similar to Bosch M 797 (), has 81. pin connector and is produced at two different manufactures. Itelma (The first element in the firmware designation is the letter “I” and the prefix 32 or 82 in the marking ECU) and Avtel (The first element in the firmware designation is the letter “A” and the prefix 31/81). These control units are absolutely interchangeable in firmware and wiring, that is, 31 units are identical to 32, and 81 are identical to 82. Units for 8 V and 16 V are incompatible, because in 8 V there are no control keys for 2 ignition coils. January 7. 2 is compatible for wiring with Bosch M 7. 9. 7, that is, they can be exchanged for each other (of course, correspondingly equipment (8 or 16 cells) and with its own software).

The software of these ECUs is a logical continuation of the January 5 family, i.e., it works practically according to the same algorithms. Accordingly, it is possible to implement the function “simplification” inaccessible for Bosch M 7. 9. 7 to the standards of Russia-83, exceptions from feedback calculations for DC. January 7. 2 is fully compatible with Bosch M 7. 9. 7 (M 7. 9. 7) wiring and can be interchanged based on engine parameters.

There is also an ECM variant based on January 7. 2 for the “classics”, without the detonation channel and for “Kalina”. The variant for Kalina (11183) differs in hardware by the drivers for controlling the adsorber valve and gasoline pump, therefore it should be used only with Kalin firmware.

Almost all cars from the end of 2005 are equipped with January 7. 2 and Bosch M 7. 9. 7. systems. All other systems are discontinued and are not delivered to the conveyor.

M 7.3

The people often call it January 7. 3. This is not true. This ECU is produced and installed on the VAZ conveyor for cars of the third environmental class, produced after November 2007.

Blocks are produced by two Russian manufacturers. Itelma and Avtel. The software for front-wheel drive VAZs of the 308 (1, 6, 16 V) and 317 (1, 6 8 V) series is not compatible with these manufacturers. Although the blocks are identical in hardware, the software uses the capabilities of the processor in different ways and you need to upload the software only in accordance with the block manufacturer. in the “Itelm” ECU only the “Itelm” software (I 308., I 317.), in the Autel ECU, only Avtelovsky (A 308., A 317.). The software for the “classic” is getting easier. the same software can be used to program the computer of any manufacturer (A 327. or I 327.).

Since the controller M 7. 3 is almost identical in hardware January 7. 2, then, with some limitations, M 7. 3 can be redone to work with software I 7. 2

M 7.4

The first M 74 ECUs for Samara vehicles (models 2113, 2114, 2115) had different hardware versions, respectively, and the firmware in them was non-interchangeable.

These three firmware not allowed change among themselves:

I 414 DA 01 (11183. 1411020.02)
I 414 DB 02 (11183. 1411020.02)
I 414 DC 03 (11183. 1411020.02)

That is, you can write in them only "native" software, or on the basis of more recent, universal (see below).

Later, AvtoVAZ released the so-called “universal firmware” I 414 DE 06 (11183. 1411020.02), which takes into account all the hardware differences and which works instead of any of the above in any previous hardware ECU. In firmware I 414 DE 06, a factory defect in air calculation was also detected, which caused the electric inductor to go into an accident.

The latest firmware from this series I 414 DE 07 (11183. 1411020. 02) eliminates the problem of the throttle going into an accident by narrowing the throttle monitoring range. We use it instead of all the above firmware.

Separately, it should be noted ECU with firmware I 414 DD 04 (11183. 1411020.02). Tuning into this block only needs to be done on the basis of “native” software, earlier or later software will not work correctly, when programming with any other software the CE lamp will light up (hardware difference. connecting to another processor port), while there are no memory no errors.

With firmware M 74 for Kalina cars, the situation is similar, the first firmware of this series were not interchangeable with each other.

I 444 CB 02 (11183. 1411020.52)
I 444 CC 03 (11183. 1411020.52)

Then came the “universal” firmware I 444 CE 06 (11183. 1411020. 52), there was also a factory defect and it was fixed by the next serial version I 444 CE 07 (11183. 1411020. 52), which, in turn, was present defect with “speed overrun” with the air conditioner turned on and coasting.

The problem is fixed in the next serial version I 444 CE 08 (11183. 1411020.52), which can replace all of the listed software.

Also separately noted ECU with firmware I 444 Cd 04 (11183. 1411020. 52), I 484 GU 17 (11186. 1411020.22), I 484 GKA 1 (11186. 1411020.23). In these blocks, it is desirable to do tuning only on the basis of "native" software. When recording other software, regardless of the type of hardware, the ignition key resistors burn out. Be careful.

Starting with software version xxxxx I xx (e.g. I 444 C I 07) instead of an external EEPROM chip, the computer uses an internal FLASH processor to store data. Naturally, you need to change only to this or earlier software. When working with EEPROM ECUs, always select the appropriate location for the data storage area. The “Combiloader” programmer, when working with the FLASH controller, the area (0 xC 0000. 0 xD 0000) allocated for use as an internal EEPROM is not read or written regardless of the type of EEPROM selected. In serial versions of software designed for computers with external EEPROM, this area is not used.

Currently (end of 2015), the M 74 project is developing very rapidly, serial firmware comes out with frightening regularity. They eliminate the noticed bugs, introduce new ones. In short, the process is underway. There are three types of hardware implementation of the controller board, and even under the same number 11186. 1411020. 22 different versions of 4. 1 x and 6.3 x are produced, which, of course, are incompatible with each other. M 74 is that ECU in which, if there is no reliable information, it is better to fill in tuning based on "native" software.

Despite the seeming complexity and complexity of this material. in fact, everything is very simple and after some time it becomes completely obvious, you just need to understand the commonality of the computer, software and wiring to it. That is, the interchangeability of the ECU is decided by three criteria: a) Compatibility according to toxicity standards b) Compatibility for wiring (connection) c) Software compatibility.
