Suggestion
Both DME's run Motronic 7.2 but since the displacement is different, you'll need to change the maps.

Suggestion
When you say that it doesn't run, do you mean that it "cranks, but does not start", or do you mean that it doesn't "crank at all"?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I bought an unrunning Boxster and tried to fix it myself. I gave up and took it to a Porsche shop. The shop is not a Porsche dealer, but are well known, and don't have the tools to unite the CPU (DME) with the immobilizer. I didn't ask, but can we just send the two boxes to a dealer shop, or does the dealer shop need the car to recode. Also I'm in Des Moines, Iowa, so any known certified shops in this area that can do this work. I'm thinking Woodhouse in Omaha.
Can you be a little more specific as to what is going on with your Boxster?
Does your Boxster have a complete Immobilizer and ECU Set with at least 1 Remote?
When you say that it doesn't run, do you mean that it "cranks, but does not start", or do you mean that it doesn't "crank at all"?
I'll be able to explain to you what you will need to get the car running.
The car is being worked on by the Woodhouse Porsche Dealer in Omaha. I'm from Des Moines, Iowa, and had it at a popular shop. They told me the car turns over, but doesn't start. That the ECU DMI needs to be programmed with the immobilizer, and they don't have the programming tools. They recommended that I go to a Porsche dealer for this programming. So I sent it to Woodhouse in Omaha. It will probably cost a fortune but hopefully they can fix it.
Programming is a very loose term, and if that is all you need to "start your car", then you shouldn't have to "pay a fortune" maybe only $300.
All they would do is get the codes from Porsche to "link" the Immobilizer and DME.
Good Luck.
Please update when this matter is resolved. We like to know what you paid as it seems the pricing is all over the place, especially when only Porsche has the codes and you are at the mercy of the dealership.
Thanks for joining in on this conversation. Several of us probably have questions about this topic.
For example, original poster did not answer if he had the complete set. However, I do, BUT, isn't there always a BUT? My set was pulled from a running 2002 S 3.2L that was wrecked. I'd like to use the set in a 2001 base 2.7L. My understanding is that the DME (CPU) will need to be reflashed to work with the 2.7L. Correct? It is also my understanding that one would need the PST2 or PIWIS to do the reflash. Is that also your understanding? I thought I read somewhere that there was a third part source for equipment that could reflash a DME. OR... from your user name, it appears that you might also do this kind of work.
What can you say to these questions?
Thanks,
Joe
$300
is
a fortune just to press some keys on a test set to re-align some electrons. This really should cost no more than $75. My indy will do it for regular customers at no charge.
Yes. Both DME's run Motronic 7.2 but since the displacement is different, you'll need to change the maps.
Yes, a PST2 or PIWIS is needed. Some indy's and 3rd parties can do this also like Softronic.
I have reflashed 7.8 DMEs as recently as last month and as I said above a PST-2 with the latest version of software only asks what model of Porsche it is and what part of the world the car is being used. It does not ask for the displacement.
I'm not an engine swap expert but I am a Motronic fuel injection/control system junkie. As such, I can't say that I have a PST2 (wish I did!), but here is a reference (of many that can be found on the interwebs) about swapping the 2.7 and 3.2 with DME 7.2. If this info is incorrect, I apologize.
You can swap in any replacement engine of the same displacement from 2000-02 without having to remap the DME. (for example, a 2001 3.2L Boxster with a blown motor can accept a 2002 3.2L engine with no remapping needed).
Go to this link, then scroll down to "Boxster 2001 (2.7L & 3.2 S)";

The Porsche Dealer is finished. The car runs good. It cost 450 for a new security unit that is under the passenger seat, and 200 to install. Plus 190 for a key fob and 60 to program it. The dealer tried to sell me a bunch of stuff. I did have them change the oil and inspec it. That ran 250. Now my engine light is on, my air bag light is on. They said it will cost about 300 to have them fix the air bag light. They don't know why the check engine light is on.
If they can't shut the airbag light off and can't read the cel, then they are morons.
They need to shut off the airbag light and check the cel
for free.
