MOTRONIC 4.3 Volvo T5/R binary files

[Turbo77]

No prob mate. There's still heaps of work to do on MotronicSuite of course and if more info become available i'll help out in any way i can. It is just a little hard for me to work this out on my own as i don't have anything that smells like Motronic at this point (except for the bin files )

Would a damos-file and bin for a v70r with Motronic 4.4 help?

[Dilemma]

A little probably yes. The main problem is that the damos file does describe where which map is and probably even names it but it does not decribe how to extract ALL maps programatically from the file. This is what i'd prefer to do but i wonder if it can be done

[Frpe82]

You both have PM's.

Hi Dilemma,


I've got a question (being new to all this). I have an old 850T and looking at the boostmap (with the sacaling suggested by your software) it looks kind of odd I think. Top row (at maximum load) has the following requested boost levels (decimal style).

110 120 122 122 122 122 124 128 130 136 143 155 152 144 136 127

...which (I guess) corresponds to 0.28 bar of boost at about 4 krpm for instance in your Motronic Suite. That's however much lower than the actual boost and taking into concideration what the wastegate actuator gives as basic boost pressure, all values below 140 (decimal) seems to be "a bit off" to say the least...
Shouldn't there be some sort of factor here as well or is/are there another map(s) present to ad on top of these values?



Any input is greatly appreciated,

Warmest regards Fredrik

Hello there can you help me i have find all the maps that i need for my volvo but cant find where can i removed the boost limit that is about 1.2 bar can you tell how to and where is the adress

THank you

Hi everybody,

first of all I would like to say that I am really impressed by what you people are doing here. Very nice work! And thanks a lot for sharing all this with everybody out there.
The Trionic tools make me want to buy another Saab!

I would like to ask a few questions.
So far, it is possible to identify quite a few maps and modify them. As I understood, there is no injector constant or anything similar within the Motronic code. If I wanted to use different injectors or a different AMM size, I would have to rescale the whole map(s). Is that right? What about the load axis in this case? Can this stay the same? One thing I do not quite understand is that the load axis is supposed to be based in injector energizing time or something similar. Therefore it should have to be scaled when changing to different flow injectors.
If there is no injector constant, the load scaling should be different for 850T5R and 850R, as those cars have different flow rate injectors. Or am I missing something? The maps seem similar for T5R and 850R maps (VE map), so the scaling factor must be included somewere, already.
What do I have to do for example to use the RICA 850 T5R map in an 850 R?

What about the rev limit? Has anyone found out where this might be, as this is usually raised within modified files.
And what do I have to do in order not to hit the fuel cut when I increase the air mass flow by increased boost levels?

Best regards,

Tadek

Hi!
Does the 850R use a different MAF sensor than the T5/T5r? If so, could it be that the injector constant is fixed in the MAF sensor that is programmed for certain injector flow.
I know that the older FORD EEC-IV ECU cars had different MAF sensors for different injector sizes. It' meant, if you wanted bigger injectors on your car (1.6 ZETEC), you could swap bigger injectors and MAF from another EEC-IV car (2.0 ZETEC) and the engine would run normal and not overfuel.

One question I had is if anyone has figured out how to Disable the ECU looking for the Automatic TCU. Converted a car from Auto to 5spd and the there is a check engine light because its looking for the trans controller.

Might work if ya find an ECU for manual tranny, same generation of course, or the suitable bin.

All the Volvo range from 850 to V70 MY1999 used the same MAF. Volvos MAF was sufficient for most tuning mods. Ford save money anywhere they can thus using different MAFs on their crappy cars.

[rawill]

I know I am probably in the wrong place - could mods please shift this to the right place.

I am wondering where I can find out which if any out which if any Volvos have T5 ecus.

I am wondering about getting a Volvo, but because I have learned to use T5 suite it would be nice if some Volvos had the same ecu.

[Dilemma]

None i'm afraid ... T5 (Trionic 5) was only on saabs.
Volvo had Motronic (Bosch).

New question..........

I am currently working on finding the maps in my M4.4 file for my 850 AWD. As has been said before on here the second half is a copy of the first half of the file, but as I've been trying to find the maps I have found that some of the maps aren't duplicated in the second half.

Anyone know a reason for this?

RPM and speed limiters are duplicated for example, but the turbo map isn't. Or am I just missing it?

[rkam]

Please upload the file.

[bomb192uk]

Have checked with all my other M4.4 files and they are the same, where the duplicate maps should be the code is just a load of 02 hex

Have found a number of maps and support points (boost, engine timing, rpm scales, etc) in my awd file by cross referencing from a V70R bin and damos file I found. Seems to all make sense so far.

I have been studying T5 standard and tuned files to see which maps are changed (only since last night) and have found some engine timing changes, boost map (obviously) and speed limiter, but have much more to look at.

Anyway, see attached file. The 850 AWD ecu was the first incarnation of the M4.4 and is different to 4.4 ecus in the V70 models (not sure why exactly, must be some different hardware) and thus a later 4.4 ecu can't be used in an 850 AWD.

The A16 line is connected to pin5 of the B57568 chip on the back side of the circuit board.
I have not found any info on this chip, but it seems that when pin 2 is high, pin5 is high, and opposite.
Pin2 can be traced to P5.7 of the CPU.

P5.7 thereby controls address line 16 of the FLASH.

P5.7 is closely related to the status of RAM_25.5

In damos file RAM25 is only described as flagbyte FLAG1

The missing maps might give us some clues on when and how often the upper/lower 64k banks are used.
It could be several times per revolution.

Please help tuner, Now i used rica 304hp binary for my volvo 850R and boost about 1-1.06 bar only (first gear peak boost 1 bar only , 2nd 1.06 only. I need more boost(I'm expect about 1.2 -1.3, If you have other bin file (rica310hp or more) please send it to me please. Thank you very much friend.
Best Regards

You do not want to go there, your rods come to say hello.

If you really want (and you Really know what you are doing), you can found all the needed info here in this forum to make it boost that much, no one should make that kind of file for you.

That "rica 304hp" wont give you 304hp, most likely around 280, depending what dyno you use, there is no such thing as "rica 310hp", hardware wont support that much horsepower.

i have tryed the rica bin and my car dosent start... it dosent work for me on my 96 850 t5 automatic
