This M112 engine will it work normally with these errors?
Depends on how you define "normal" :). The ECU, after the battery connection, with its adaptation data erased, will start in default mode and check all the relevant sensors over some driving cycles to set up adaptation data. When you start the engine, it will start in open loop mode, meaning, not checking most of the sensors (MAF, O2 sensors and so on), so it runs in this mode, based on throttle angle position to calculate fuel injector timing. When the sensors are ready, it goes into closed loop mode to adjust air/fuel ratio precisely. So, if your car is stuck in the open loop mode, and thinks it is perpetually idling (P/N setting), the fuel consumption will not be good.

It would be interesting to know how this julie emulator works, and how it communicates with the ECU. At the end of start sequence, the ECU updates the authorization code to be loaded into the key, and maybe the emulator is not acknowledging it.

For what's it worth, I remember that Hifu manufactured reluctor rings for his conversion to make it work.
3 years on the project and still going? Unfortunately that how it often goes.
Although with Coronavirus restrictions people are forced to have more time at home.
Good luck to have it finish.

In May 2017, I started working in Sweden, I returned to Poland 3 months ago. And I continue building "project".

Without immobilizer emulator, the car did not start, I think that the DAS and EZS problem is caused by the lack of CAN connection to the ignition switch. What do I need to connect so that the motor controller sees that I am not holding the brake and is in position D? maybe I can remove the automatic transmission? this is a 1997 engine driver

I think the only people who might can help you with software issues are Deplore and Hifu.
You took the project that require high end hacking skills beside mechanical skills. Talk APT29 level hacking. ;)
Good luck.

I thought you had an M112 with its controller. In the USA, the 1997 model has M104 engine and its controller of course. In any case, the brake pedal information and the gear information is passed to the ECU via the CAN bus. The brake pedal monitoring comes from the Traction module, and the gear information comes from the TCM that you t have neither.

I actually have one or two julie emulator on hand. It's basically a tiny PCB with four wires soldered onto the ECU -- power, GND, CAN L and CAN H.

You virginize the ECU so its blank, and then with emulator soldered on, you use SDS to "marry" the ECU to the car.

In this case the julie emulator monitors the CANBUS and then intercepts the data packets that is meant for EIS/EZS and feeds its own.

So by marrying the blank ECU with emulator, the emulator supplies its own ID (since it intercepts the EIS packets) and thus the ECU is married to the emulator ID, not the EIS ID.

Therefore when you turn the ignition to pos III, the start signal is sent via CAN to ECU, ECU checks the DAS by querying the EIS for the ID....but emulator again captures the packet and feeds its own ID, then ECU sees everything is all good, then starts the engine.

Basically in this case you take out the EIS out of the equation completely. Amusingly enough, in order to install the emulator you need to have a functioning EIS and key to begin with.

Therein lies the problem. Without a EIS that is communicating properly with the ECU, the julie emulator will not work properly. Once the SDS marries the ECU to the emulator, THEN you can take off the EIS and do whatever the hell you want to do.

Yeah, I watched a video on installation. But the drive authorization is done when the key is in position 2 (run) When the key is turned to position 3 (start) an the EIS raises the terminal 50 (start) signal to the ECU. It is actually a wire from the EIS to the ECU (the purple wire). I think the guy in the video is just turning the terminal 15 off and on to the ECU to signal ignition off and on. I did not see any EIS or key used though in the process.

I did exactly the same as in the movie. I sent the ECU to a company that specializes in this. next was personalization.
without HTTTrack personalization, the engine did not start,

I believe you can get a W210 with M112 with a manual transmission (at least in Europe). Isn't it possible to tell the controller, you have manual transmission ?

my w210 originally has an automatic gearbox, I installed a manual gearbox from w202 2.4 v6 , and I don't know if it is possible to code a manual gearbox ??

someone once said that you can not code controller in the m112 engine from 1997 - you can only code the ECU from 2000 up

Hi, change of plans, I got angry and the engine is already scrapped. I put OM606 with mechanical injection pump, i wanted to mount in my w123 but well ....
I need rear sump oil for this engine, from which engine model the oil sump will fit well ??? And what with the oil pump ?
I find this W211 3.2CDI R6 6480140302 ?

Sad to hear it, but it happened before that after 3 years the owners had to scrape the project.
Ironically you did reverse what Hifu did.
He started with mechanical W124 and put digital engine and transmission in it.
But than Hifu is exception and to date the only 1 who reported success on this scale.
Couple more guys in UK updated the engines to top dozens who failed.

but there is one more option,

I just talked with my friend, he says that he will can change informations about the gearbox in ECU and make a manual gearbox.

Will this change improve anything?
Did the EZS DAS errors kill it all?

Coding it for manual will not fix the DAS start error.... You need to fix the Julie emulator first, when the car can start reliably, then you can code for manual.

I thought the car starts and runs. No ?

It would have been easier if you started with an ECU from a compatible car with manual transmission. If your car starts and runs, DAS does not come into the picture after that.

The engine start normaly, i have only errors when i make diagnose.
When i will make coding a manual transmission it will be ok ?
(power and fuel consumption ?)


these errors will remain,
EIS, DAS, ABS, ESP, INSTRIMENT CLUSTER, CAN connection, OIL SENSOR

I believe it will, as the engine provides minimum of torque when it thinks it is idling.

The EIS code will remain and will not matter. The ECU, after the car starts, it will send new key code to the EIS and waits for EIS acknowledgement. If not received. It will generate a fault code.

Once you have the changes for manual transmission, you can scan and check what codes are still there and what new codes come up. Make sure it can be reversed to how it is now, if things do not work better.

Suppose: I will have manual gearboxes in the controller.

With DAS error, EzS error, ABS / ESP/ASR error, P0500 and INSTRUMENT CLUSTER communication failure

Will the engine run normally? normal fuel consumption? normal power?

Now the car starts fine every time even though it shows DAS / EZS error

If the change information about gearbox in ECU will not change much because of these errors in the example above, then I throw the engine in the trash.
I am asking because I want to be 100% sure that it will work well, if not, it's a waste of money, I prefer to invest in a different engine.

Without ESP, that might get dicey. ECU usually gives full power when it detects that the car is in motion....and it knows that from ESP module.

What is your current symptoms that you have with the car as it is?
