Bosch 0261203069 XDF needed. E31 Euro 850CSi.

Post by omegaman »

Hi Guys,

I'm doing a little experiment with my 850CSi and need an XDF for the DME's.

I have read the original file from one of the DME's, it's available here:

https://dl.dropbox.com/u/76310913/850cs ... dleECU.bin

In Hex the file shows similar strings to the standard 850 bin but the 352 XDF doesn't match up.

I have the paid version of Tunerpro, I'd like to learn how to create the XDF for my car as I feel that would help me understand the DME operation. There seems to be very little in the way of info online for producing XDF's.

Any help would be much appreciated.

Thanks for looking :)

Rare DME and not much Info on the EML unit's. The software in this DME is a little more complicated but not hard for me to tune

Ok I now have an XDF for my DME's I can start work on my car.

Does anyone have any experiance using 2 Ostrich 2's at the same time? 1 for each DME. Would EmUtility be the best way to go ? Or would using 2 computers be better ?

Has anyone attempted BMW V12 setup with Emulators in the past?

I have to install 2 Innovate MTX units first so it will be a week or so before I have time to install the emulators.

I've been spending some time looking at the code for these DME's.

I found the 2 eproms has different Checksums, this was down to the DME ID section found at $

DME1 / DME2
1E20: 33 34
1E21: 37 36
1E22: 32 31
1E24: 30 31
1E25: 39 34

5 difference(s) found.

It was the details printed on the white sticker on front of the DME case. 372.09* on DME1 and 461.14 on DME2. Other than that the files were identical as would be expected.

I should have the emulators up and running in the car this Sunday which will help confirm maps and help add more to my XDF.

Hi I am interested in the 850csi xdf file. Have been trying to find the s70 xdf but no luck. Can anyone convert s70 bin to xdf? I can provide the bin file.
Thanks.
