173DME with real Dinan chip

[ianxflo]

probably a noob question, but if I have a 524 dme in my 1991 325i sedan, can I swap a 173 dme in? Or do I have to stick with the same dme number?

I just searched, and got this result

Finally, if you've tried all of the approaches outlined above, and your DME unit still doesn't work, then you will probably have to replace it. A little known secret is that many of the DME units are exactly the same across different automotive manufacturers. The only thing that is different is the programming chip contained within the unit. If the DME unit is the same version of Motronic, has the same connector on the unit, and has a removable chip, then chances are it can be a good replacement for your failed unit. This means that a $10 DME from a Volkswagen in a junk yard may work in place of the $650 one that a BMW used parts dealer wants to sell you. A few customers have experimented with this by swapping BMW DME computers with the ones used on the Porsche 944 and 911, and they have experienced good results. Some units won't work (it's a matter of trial and error), but many will. The main thing to remember is that you have to have the same software version of Motronic, the connector must be the same, and you must swap the chip from your DME to the new one.

Although I haven't done enough testing to generate a table of replacement units that will work, here's a table that shows most of the models, engines, and DME versions for BMWs:
