Hey guys,

I just recently picked up a Burn 2 and was able to read a couple OE chips. One from an E34 540i Auto, the other an E32 740i Auto. Both with chip numbers 1 267 358 720, 1 744 050. They are subtly different from each other and drastically different then the 357689 404 tune on the TunerPro site.

Hope it can help anyone else out there. Cheers -Mykk

Also, here is the XDF I've made for the 404. It's far from complete, but I made it by pulling apart the hexcode and using the readily known axis identifiers. It also has automatic checksum correction, just remember to save your bin before loading it to your emulator or burning a chip for the checksum correction to take effect.

Again, it's not perfect and it's not yet finished. The temperature factor & offset have sent me through a loop so for now temp axis are improperly labelled. But it's far better then the 404 XDF available for download on the site.

Here is another E34 540i Auto 404DME that came in. Production 6/1994. Chip # 1 744 050, 1 267 358 720.

It is slightly different then the previously posted E34 540i and E32 740i tunes.

Here's a 12/1995 E38 740il, 484DME chip numbers, 1 744 605, 1 265 358 772. This is an EWS file. It will not work with the existing XDF, I believe this this to be a DME for the non-vanos M62B44. I'll spend some time with it in order to make an XDF.

EDIT: Midas' XDFcreator has recognized several maps in the 484 .bin. I'll spend some time with it and see what I can recognize and what not. I already see Idle, PT, WOT Fueling and also Idle, PT, WOT ignition. From what I can tell, despite the data side of the .bin being drastically different and all the MAP addresses are moved around the tables themselves are very similar to the 404 tunes.

Here's a quick 484 .xdf with the maps identified by pulling apart the hex code. The axis are unlabelled since that is the most time consuming part of the process. Checksum correction is in this xdf. If someone can find it useful and build upon it, that would be cool.

If and when I find out how to disable EWS in the tune I'll update it to the .xdf

Hi, could you please check XDF link ? It's the same link for .bin file as in previous post. Thanks
