VS M4.4 tuning dead? Start again here?

[GranTouringRacing]

Rkam,

I have everything working for 4.3 now and was able to get full eeprom reads using your program which is awesome.

I totally cannot get the 4.4 to read although it does write on everything.

If i was able to read the eeprom on them somehow that would be awesome as i don't want to start pulling chips out to read eeproms but i do have a couple of ECU's i do need to know what was on them first before tuning.

I'm no where near as technical as you and some things you say do confuse me slightly lol, but if you can suggest anything that can get this to read the 4.4 eeprom on Volvo Diag that would be awesome?

It's worth noting however, that Motronic Suite doesn't actually support 4.4 communication and reading, i assume it once worked on VolvoDiag because it definately seems like it's a rejection of the ecu to read, i wondered if it was an IMMO issue but i flashed a 4.4 with IMMO off bin and it still doesn't work!

If i ran this program in the car would that make a difference as at the moment i am just doing it all on the bench?

Also it took about half an hour to read a 4.3 with your program yet it was about 3 hours with the same ECU on MS to do the same thing, the only thing i can read the eeproms on is a hex editor, loading the read EEPROM back onto MS doesn't show any maps, but i'm not hugely familiar with MS yet to see if i need to do something else?

Thank you again, i appreciate all your work and effort!

Scott.

Motronicsuite is made by Dilemma.
I've helped him with information on K-line communication and M.4x hardware.
Dilemma helped me a lot with Volvodiag which is C++ based on a program Omegadiag.
My own tools was before this written in Visual Basic.
Although I was able to implement Volvo protocols in the C++ program, I quickly got into trouble dealing with Windows GUI stuff.
Therefore I have kept the buttons that doesn't work on Volvo in case I need them for something else.
Replacing the program code I can manage, but adding a button is much more difficult for me.

Lately I have been using Tiny C Compiler for command line tools with DiCE.

Communication in Motronicsuite seems to be more difficult to make and keep running.
Motronicsuite is programmed in C Sharp, while Volvodiag is in C++.
Maybe C# is more affected by Windows functions stealing time.

Does your M4.4 fail to communicate on both old KWP and new D2 protocol?

Have you flashed a file with modified datalogging?

If you can send me the M4.3 file, I can take a look. But I dont have any good description or way of naming the maps correctly. I'm no tuner.

Hi,

So Miraculously it all seems to have started working now?

I am finding that when i load the read files though they do not show up any data on either TunerPro nor Motronic Suite and all data is 0.000, although looks like a full binary file in a hex viewer?

I have asked a few UK tuners that seem to think that this only gets the data off one off the memory banks, does it pull it all?

Thank you,
Scott.

If you selected 27C256 in the first window, you only got the first 32kB.
I was not able to make that box change when selecting ECU.

On M4.4 you only get the last 64kB when running in normal mode.

Hello everybody!
If there are programmers or people here who understand how to edit XDF files correctly, then it would be good to add a function for selecting the fan response temperature in motronic 4.4. Because due to the high fan response temperature (105 degrees Celsius), there are many problems in hot countries. The cooling system often fails. I replaced the thermostat and put an additional sensor to the temperature that would turn on the radiator fan already at 90 degrees and turn it up to 82. But it doesn't always work correctly. I would like to add this function directly to the firmware. So that you can change the temperature of the fan operation. I think it would help a lot...

There was a 'fan control" XDF uploaded at one point on the M4.4 Wiki or the VS thread ("REV6-RadFan-Control.xdf"). I don't know if it worked or not.

I was looking for such an XDF, but I didn't find it. Do you still have the link or the file itself?

I have it. Send me a message with an email and I'll forward it to you. No guarantees on how well, or if, it works though.

[Josya]

Thanks! I somehow miraculously found this file via a link to dropbox, which was cached by Google. I will try to flash it...

[Chuck W]

OK. I figured it was floating around out there someplace still.

It was put together for use with the "standard" 607/608 bins from the Wiki.

Post back up with results.
