Tell me about replacing the Bosch ecu for January... the price is Bosch 1411020-70... is it interchangeable with January 5.1?
or what needs to be changed or redone? Google is already thinking something, but I’m only getting more confused

For example, we take block 2112-1411020-41, flash it like January 5.1.1 without DC (lambda), let’s say with this firmware J5V07J28 (2112-1411020-71) or for example this J5V13L05 (2111-1411020-71) and everything works without any changes in wiring! Attention, new blocks are produced with a HIP9011 knock sensor chip; in such blocks the firmware begins with the letter A. (Looks like this: A5V05N35). There is nothing terrible about this, only the firmware must be appropriate. There is specially developed software for changing any firmware for HIP9011! Hope I helped. Good luck.

thank you) I understand there won’t be any problems... I’m replacing it simply because it will be necessary to flash it for certain hardware... and January is generally from the rally eight, so sew it any way... the main thing is the wiring and sensors...)

Wires and sensors are complete nonsense! Everything is done at once!

In short, everything fits? stuck the brain in, flashed it and went? so I understand?

I installed for myself what was on hand January 5.1.3 2104-1411020-01, but I soldered the HIP9010 chip into it, this is the detonation channel and several more piping elements, as well as phase sensor control elements (for phased injection), that is, now my unit is hardware compatible with January 5.1 2112-1411020-41 and January 5.1 2111-1411020-61 and can be installed instead of any January fifth series with the appropriate firmware! This unit controls the Euro 2 2112 engine with firmware J5V05N35. Something like that.

And the block January 5.1.1 2111-1411020-71 will install without any modifications at all! It has simultaneous injection and controls the injectors via the Oxygen Sensor heater switch! - well, I don’t have an oxygen sensor... and in the rally eight, where I’m going to get the brain from, it’s unlikely to have one... by the way, the brain is January 5.1.1, in my opinion... but what they did with it next, I have no idea... what program is there... I just know that to sew it in Togliatti we went to some fierce master...

By the way, if I suddenly write or write some nonsense... it’s just that the concepts of “I” and any “electronics” are probably not compatible concepts)))

ugh) figured it out) thanks again)

In short, they brought the block... January 5.1 2111-1411020-61 code for j5v03h21... but I remind you that it was stitched, it was on the rally 8... now you can’t tell me what I need to install it...

where to put it, what kind of engine, what is in the engine (pistons, connecting rods, knee, what camshaft and receiver)

Are you going to change the wiring? Or will you install it on the system you already have?

in short, the engine is 2111... the engine has a full 10-volt bottom (elbow, connecting rod, piston), everything will be covered by the 16v head... in general, the point is, I'm changing my Bosch for this January, so that there will be an opportunity to flash it online... so I'm interested in what's on The wiring needs to be redone... or what sensors should be replaced... in the future I might build a turbo, so I’m also interested in how to install the DTV and DTV...

Then you definitely need to knead the wiring. and on the 10th bottom you can’t put 16 valves on just like that. The pistons either need to be modified or changed, and there is a difference with the cylinder head bolts, they need to be shortened and holes picked out in the head.

Yes, this is not a problem) I’m just a wooden person when it comes to electrics... can you tell me where to find the information, where to connect what? Or is it easier to buy wiring?

it's not the same for everybody! I would improve the existing one. only in addition to the wires and chips for the sensors, you also need to add “lyre” type contacts to the ECU connector.

Those can be replaced instead of Bosch MP7.0 meringue alterations? do you need lambda?

Damn, please tell me! brains January 5,1,1 2111-1411020-71 Is it really possible to connect a phase sensor without major changes in the wiring and do a phased injection or the next one or whatever it’s called =) but without an oxygen sensor! is this real?

If it is possible to reflash, then Y5.1 or VS5.1, January is more common (there are more firmwares), in VS the electronics work a little more interesting (with it the power is slightly shorter, higher, with other identical components). The injection does not have to be done simultaneously; it can be done in pairs-parallel with the firmware.

This wiring can be changed. If you understand it yourself, it’s easier, but you can go to a good electrician.

Dear customers, in order to avoid errors when sending an electronic engine control unit (ECU, ECM, controller), in the “Comment” line indicate your car model, year of manufacture and number of valves, engine size.

The Electronic Engine Control Unit (ECU) is the “computer” that controls the entire vehicle system. The ECU affects both the operation of an individual sensor and the entire vehicle. Therefore, the electronic engine control unit is very important in a modern car.

The ECU is most often replaced by the following terms: Electronic engine control system (ECM), controller, brains, firmware. Therefore, if you hear one of these terms, then know that we are talking about the “brains”, the main processor of your car. In other words, ECM, ECU, CONTROLLER are one and the same.

Controller 2111-1411020-70 belongs to the M1.5.4 BOSCH class, installed on VAZ cars from 2000 to 2006. This unit belongs to the environmental standard P-83, i.e. , without oxygen sensor and adsorber (catalyst). Engine 8 valves, volume 1.5 liters. Has a standard 55-pin connector.

Product features: Electronic engine control unit (catalog designation “BOSCH”, 0 261 206 683, 8701 0755 M1V13S64 or M 1 V 13 T 64 Russia), using various signals from engine sensors, controls the composition and amount of fuel supplied to the engine.

serzhkorzh › Blog › Compatibility of VAZ ECUs of different types

Each type of injection is equipped with its own ECU, software and wiring. Hardware compatibility means the ability of ECUs to replace each other.

Simultaneous injection. Bosch M1.5.4 1411020-70 January 5.1.1 1411020-71 VS 5.1 1411020-72

Within this group there is an old modification of the Bosch M1.5.4 1411020 block. It has a different type of knock sensor - resonant and is interchangeable with the ECU of this group only together with a knock sensor. Usually this unit is replaced with a more modern one with a new knock sensor.

In pairs - parallel injectionBosch M1.5.4 1411020-60 January 5.1 1411020-61 VS 5.1 1411020-62

These two Euro II systems, with DC and adsorber, are hardware compatible and can interchange each other.

A special case here is the ECM group for “classics”. They differ from the “parent” ECMs; they do not use a knock sensor and, accordingly, elements of the DD channels are not installed in the ECUs themselves. Bosch M1.5.4 2104-1411020 January 5.1.3 1411020-01 VS 5.1 1411020-02

Phased injection. Bosch M1.5.4 1411020-40 January 5.1 1411020-41 VS 5.1 1411020-42

All three ECUs in 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 that meets Russia-83 toxicity standards, without DC and adsorber - January 5.1.2 1411020-71

The options you considered for mutual replacement of ECUs are presented from the manufacturer’s perspective.

From the standpoint of software and tuning (chip tuning), the replacement possibilities are somewhat wider. But there are corresponding restrictions. Let's look at the options for interchangeability using the example of the most common type - January 5.x.x. The interchangeability of the “VS” and “Bosch M1.5.4” ECUs is carried out according to a similar algorithm.

All ECUs (within their own type) are built on a single platform and differ mainly in the switching of injectors and DC heater. 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, differing only in the firmware, this means that, for example, by writing the firmware from 2111-61 into the 2112-41 block, it can be installed instead of 2111-61 and vice versa. Further:

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 that the DC is turned off), but 2112-41 or 2111-61 block will work perfectly instead of 2112- 71 with the corresponding software (2112-71), with one caveat: the harnesses for 2112-1411020-71 of different years of manufacture may vary. More precisely, there are “new” harnesses in which the 1st injector (pin 23) is connected in the connector to the recirculation valve (pin 17) and then goes to the 1st injector. As a result, when the ignition is turned on, the 1st injector is constantly open. When replacing, it is necessary to check this circuit and, if 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 microcircuits to the block, turn January 5.1.1 (or 5.1.2) into January 5.1. January 5.1.1 lacks a couple of microcircuits, one of which is the injector driver, the second works with the adsorber, recirculation valve and exhaust pipe length. The injectors in January 5.1.1 (as in any other simultaneous injection system) are controlled through (!) the oxygen sensor heater channel. This means that any block with DC support (2112-41 or 2111-61) with software for 5.1.1-71 will work in place of 5.1.1-71. There is no such compatibility with January 5.1.2, because this ECU does not have control elements for the DC heater, which is used in simultaneous injection 5.1.1-71 as an injector driver.

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

In practice, any unit can be installed on a car with the wiring alteration or replacement corresponding to this unit and the corresponding software. But you need to remember one nuance - ECUs have different drivers for the Phase Sensor (PS) channel; they may have different requirements for the polarity of this sensor. Therefore, if, for example, Bosch M1.5.4 refuses to start instead of January 5.1, you just need to swap the wires suitable for the DF.

It should be borne in mind that 2112-41 and 2112-71 blocks with the same markings may have hardware differences. It is very easy to distinguish them - the new hardware implementation leaves the factory with “J” series software (or newer). These block options differ in the injector driver microcircuit used. The old unit has SIEMES TLE5216, the new one has MOTOROLA MC33385. They also differ (among other things) in the driver diagnostic reading diagram. Therefore, on new units with old software or vice versa, driver diagnostic errors may occur, for example, the notorious breakage of the 3rd injector.

Among other things, due to the discontinuation of the HIP9010 chip (detonation channel processor), since 2006, HIP9011 is installed in the ECU supplied as spare parts, which differs in the SPI programming procedure, and, naturally, the software has been changed, which is easy to distinguish by the software marking - using the letter A instead of J in the firmware name. For example A5V05N35. “Old” firmware in such ECUs “does not see” detonation and can only be used after a small software edit using a special utility from SMS - Software.

Within the Bosch M1.5.4 group, 2112-1411020-40 and 2111-1411020-60 are completely identical and interchangeable, the only difference is in the software.

ECU VS5.1 manufactured by Itelma is functionally an analogue of January 5, that is, it performs the same functions, is compatible in wiring (that is, for example, VS5.1 with firmware V5V05N35 can be installed instead of any January 5.1 2112-1411020-41 or instead of Bosch M1.5.4 2112-1411020-40).

ECU diagnostics

ECU diagnostics involves reading errors recorded in the controller’s memory. Reading is performed using special equipment: PC, cable, etc. via diagnostic K-line. You can also get by with an on-board computer that has the function of reading ECM errors.
