DME Replace

[chris97boxster]

I looked in the parts catalog
has to be a 97 DME for a MY 97 (model year)
98 - 00 have a different number

And yes that would be cool if u stumbled across
an S motor in a 97
then again that would be a different DME

So its not an S, ok, it was probably a Typo, but I am definately looking at a DME that is 1997 model specific, or an entire new engine with DME, how much am I looking at for either? Used of course haha, Im just a concrete finisher, not made of money.

The '97 DME is a weird situation. Unlike the 98-99 5.2.2 DME, it is not reprogrammable, as Porsche didn't record any immobilizer or programming codes for these cars. Thus if either the immob. or the dme need replacement on a '97 car, they must both be replaced.

That said, the DME can be replaced with any other 5.2.2 DME from a '98-99 986 or 996 and simply reprogrammed with the correct maps if necessary (ie you buy a 996 5.2.2 DME instead of a Boxster one). Your best bet would probably be to obtain a matching pair from a wrecker as the price of the 5.2.2 DME new from Porsche has gone through the roof. If you buy a used DME separately the codes can be obtained to reprogram it to a non matching immob. (ie if you buy a new immob from Porsche) based upon the VIN number but obtaining the codes can range from easy to impossible depending on the situation.

Perfect. Thanks for all the information. Now the guy before me got Porsche to put in a new Immobilizer, and also a new Key. So I have a line on a DME from a 1998 Porsche, would I be able to match it up to that brand new immobilizer that they put in? Or do they have to be part of a set from the 98, because I imagine they replaced it with a 1997 immobilizer, but if its brand new, it should be able to be programmed I think, or no.
I just don't want to buy another computer and find out it won't work. The98 is also an automatic, and mine is a standard.
Anyways thanks for all the help so far, hopefully I can be cruising in this thing by summertime.
