I looked up 3 Boxster parts numbers and the were the same as 3 996 parts numbers. Guess the only difference is when it comes time to program it to a specific model.
I heard that the DME can only be reprogrammed once is this true? Also what computers at minimum are needed to make the car run.

Yes the boxster and 996 models that use the same DME can be remapped to run the other vehicle, as long as you have the DME and immobilizer codes from the donor dme and the vehicle in which it is to be installed.

The DME and the driveblock (alarm) computer must be matched or the car will not run. If you don't have the DME you need at a minimum the immobilizer code from your car to program into the new dme so the car will run. If you buy a used dme you will need the immobilizer and dme codes from the dme you purchase in order to program it to match your car so it will all work. This programming can be done with the PST2 or the new PIWIS tool.

Getting a sinking feeling here <_< my donor project is missing most relays, computers and the one under the drivers seat on floorboard is trashed, where is the immobiliser located or do you know where can get a drawing of the locations of the components. Lets assume mine is stripped, what would I need to get it running if I went to a salvage yard I would assume that it would all match and would I need the keys also?. Any help is deffinetly needed here. Edited by Mother

This is also what Peter Smith told me. If you get a used DME from a Boxster with a matching part number then you overwrite the Boxster program with the 996 program. But you also need the immobilizer code from the donor Boxster. I believe you get this from PCNA using the VIN from the donor. Peter has done this in the past with a PST2. He mentioned there might be some issue using the PIWIS to do this, but I forget.

Would tuners like EVO have this info for this project since my car needs to be tuned for my my custom SC install? Note my above post showing my delemia most if not all my electronics is missing I can replace the relays but if I went to a wrecking yard what is the minimum for me to get it running regarding the computers and keys, then get it to a tuner for my engine work. I hope this clear for the ones that wish to help with my project.

Yes the alarm (imobiliser) is under the seat. Your best bet is to go to a wrecker and get a matched DME/alarm set from the donor car, that way you can get all the codes (alarm, DME, learning codes for keys, transponder codes etc) based upon the donor vin and transplant all of this into your project car.

Thanks for the help, The black box in picture of the drivers seat is this the alarm? And where is the immobiliser located relative to the pictures also you mentioned the learning codes for keys, would I need the matching car (ignition) keys or can I use mine or are you talking about a different set of keys? . It would be nice to have a layout of the components but I can not locate one in my manual.

The alarm box is also the immobilizer. If you have the original keys and the proper codes you could program the old keys to match the new immobilser if you need one. If you just need a DME buy a new DME and have it matched to the old immobiliser. Based upon the state of the car, I would suggest you get the factory manuals and give them a read.

So I understand this, so I get the codes from who? or is that something that is already in the DME etc that are matched. Also is it a problem to get someone to program it, someone in the pheonix are would be nice or who would you suggest. As long as I know it can be programmed I would feel safe in purchasing the items.

The codes are obtained from the dealer based upon the VIN. If you buy the controllers used makes sure they come with the codes as most dealers won't give you the codes without proof of ownership of the car they came from. What year is your car. Depending on the year,I may be able to program it for you.

Mine is a 2000, 996 C2 manual DME is 996 618 605 00 alarm is 996 618 260 07. I ordered the Boxster S that had the exact PN#'s along with the key set and lock and the door look. Porsche said they had no problem doing it if I had the Vin# of the Boxster which they are sending me. If you can do it you are welcome to try it would be interesting. When programming it does it need to be hooked up to the DME/Alarm direct or throught a ODBC port. I should have the parts this week.
