3.4 Dme

Ladies and Gentlemen,

A long story short,

I have a MY1997 Boxter, I fitted a MY2000 996 3.4 , engine, but ran the car with the standard 2.5 DME, obviousy with reduced power.

There were some "clever" people and I think they blew my 2.5 DME.
I eventually got the car running again with the 3.4 DME(MY 2000), the 996 Security module, and the 996 FOB transponder pil in my key that I purchased with the engine.
The car goes like crazy now and the power is amazing, but, because of the MY 2000 996 security module, a few things do not work.
(obviously the 996 did not have a cabriolet top or remote boot and the frequency of the remote key is different to the security module's frequency?
The security module is from a US car and my car is European/South African..)

The soft top, the remote for the doors and the boot does not open with the remote on the key.

We do not have people in South Africa that can do programming of the DME except for Porsche South Africa,
and they want to replace both the DME and the security module with new ones, charging me a 1/4 of the cars value.

Does any body know where I could possiby buy another DME programmed with my original programming codes?,
or sell me another DME/Security module FOB key combination?

(I do have my car's programming codes for both the security module and the DME)


Regards
Pieter

All you need are new remote heads for your keys that match the frequency of your alarm computer and then have someone program them for you.

Hi Paul,


Thanks for the reply.

Is the alarm unit not part of the security module?
The security module also control the soft top, does'nt it?
If the 996 did not have a cabriolet then that output to the Boxters soft top is obviously not programmed into the security module?

Do you perhaps know of anybody that could supply me with the equipment?

Regards
Pieter

Yes the alarm system and the security module are the same thing, the unit is under the left seat.

The remote control does not operate the top at least on a US car.

No programming of the DME or alarm system is needed for the top to operate using the switch on the dash with the parking brake on and the latch released.

Hope this helps, if you were here with the proper codes and the proper remotes for your keys with the barcode tags, I could do this in a few minutes.

Does the parking brake dash light come on when you pull up the parking brake lever?
If not you may have a bad microswitch. Not uncommon problem. About US$5 at suncoast: http://www.****************************************************.com/product/99661311201.html?Category_Code=POTEBXCM

pieter -

you may have even more power available if you haven't hooked up the VarioRAM yet. the 3.4L intake has a resonance flap that opens up around 4k RPMs. it doesn't exist on the 2.5L. your new DME can control this flap; it will add low end torque.
