Let it come and we will digg into your files together

 

File+photo

 

Well, without a proper damos file, it´ll be some hard work but as long as a you´re willing we may find the neccessary maps.
I´ll show you how to work around.

Bosch ecus are much easier in identifying maps compared to Siemens, so i´ll give you a short introduction:

By having a quick look at the 32kb file, we can pretty easily identify a map between 0x1AE0 and 0x1B50. Even if we don´t know what that map is used for, we can find the exact size of the map and the axis values directly in front of the map. The bigger the map, the easier to identify.

Lets have a look at that map...

We know the exact size in x and y values is somewhere in front of the map and even the axis values. By looking at the decimal values in front of the map, we can find a "11" and a "10",

followed by some constantly raising values.


The "11" tells us the size of the map in y-direction and the "10" is the size in x-direction. The values between the map and the size-descriptors are then the entries at the individual axis. The y-axis is getting these entries:

and the x-axis is getting the following entries:

So the final map will look something like this:

Note: I already multiplied the common factor for rpm (32) to the y-axis. By having a look at the values, i tend to think it is something which works with partial load.

This way one needs to work through the file to get some decent looking maps which can later be checked for usability :eeps:

It will take you some time to mess through the file

 

WOOOOW! DANIEL YOU ARE THE BEST! so this map, for some ecutuning program, 11x10 is flowmeter. for calculate "load"

 

NOW, i write all map that i try and i know
spark timing 25BA/2844 (firts at normal condition, the second is at max load)
Injection 106E
lambda 146E (if play in winols proprietes, i know a way to see the lamda multiplier)
1E2A and other 4... Injection??? i can't try well...
flowmeter/load 1AF3
22A8 idk but it is secure a map of injiection sistem.
2533 possible knock sensor?
RPM limit: impossible to find!

 

These are the maps i found so far by having a short look at the file and using the method described above.

 

Wow Daniel! You open to me new world! So tomorrow i found all maps, so we proceded to learn how it do. A good work maybe is modify only axis ... What do you think?

 

Actual status with ols file attached

First of, you need all the factors and multipliers to make sense of each value (axis and map itself).

 

Daniel how we can find factors and multipliers??? If you want , i Can write alla sensor that the car has.
In. the proprietes of 0146e map, Please Wright in factor 128, precision 2 and click on reciprocal. You Can see lambda multiplier! On This map, i use the method of ms41.1 that is similar ECU. So go on x axis of lambda map(load) set in data source 1,2,3 in factor write 8,4 in offset 8, the dame in y axis(rpm) But factor 400 and offset 500

 

Could you take a screenshot how it should look like?

 

look

 

Well... how many lambda maps have you seen with entries of 0.96 to 1.05? Full load lambda is much more ~0.85, rather then 0.96.

Why did you choose axis description 1,2,3,4 rather then what the file itself tells us?

I really don´t trust that map description :eeps:

 

i don't think, that exist a "full load lamda map" because in certain cases, the lambda go in open loop, and this map go right only, when you drive slowly or comfortably. listen my "brain way" : SECURE map, is only this: 25ba\2844. because i test it on my car step by step. if we look at axis( this map use rpm\load), we make a series of valor,013--->150 and 025--->208. in other maps, we get same valor, like 013--->150 ( i think these are the steps of rpm) and 025--->~180 (i think this is load) what do you think?

 

I think without a Damos its all mess

The problem is, we need to find referencies for load and rpm points. I know BMW uses 32 as factor for rpm at the Siemens ecu. I don´t know if that exact same factor is used at Bosch ecus, too.

MS41 seems to be from Siemens, too?! So that would be no real help.

You may need to find out which processor the ecu is using and start disassembling with IDA Pro. As i´m definately not an expert at IDA, the work is pretty much all up to you. :eeps:

As alternative, you could try to purchase a Damos from Olsx.be, just tell them you don´t use WinOLS, rather then ASAP2Demo. Full damos file is 300€

 

OK daniel... Please don't give up This project!
The processor is ZC439505MFT20 Motorola, what is ida? lol
Ms41 got same thinghs and it Can be read with same protocol on eobd. This bms, if i remember right, on the box is write "BOSCH" But on internal board i read "siemens". How it possible?

We are going into impossibile. Do you know other way to solve our problems? It is really hard to read this processor. I see olsx. But i don't understand right how they work. I don't see a catalogue with damos.

 

You don´t see unless you have a valid ols customer number Write them an email and ask as politely as possible if they have a damos file for your ecu and if they would sell even if you don´t have and need winols, you are working with ASAP2Demo!

 

Now i try. In the same time, i got news!!! For an espert, Bosch of this Years use 40 for axis moltiplicator.

 

40 as factor for what? rpm?

(edit) looking much better try to find other factors and multipliers as well

 

i needddd heeeeeelp! XD now i'm finding rave limit, also it is 6375. Do you have ani idea to find it?

 

Unless you don´t know the other factors and multipliers don´t hesitate to find the rpm limiter. There is so much work to do before even thinking about raising the rev limit.

 

No reply from olsx
I'm searching rev limit. It is 6375, if we use the "Bosch" usually calculation, we have to do: 6375x6/0,75. We got 51000, and i have to find This value in 16 bit lo/hi.
A part This, do you have other tips? I know that bms is a m5.2 similar to 740i. And i got a file and a damos for This ECU. If i look on This, i Can see a lot of similar things. I'm disperate, no one Here in Italy can REALLY help me.

 

8minites ago i got email from olsx:
"Hello,


I've not damos for this kind of car, but i can provide you a perfect tuning file.

Keep me informed.

Best regard,


robix"
OK, My car is going right with my map also. But i need more for adapt kompressor!

 

Any idea?
