INSTRUCTIONS
Before You Order: Identify Your EPROM Chip
Your replacement DME must be configured for the correct EPROM software or memory type.
The Porsche 911 Carrera 3.2 DME uses a removable EPROM chip that contains the engine management software. Over the years, some vehicles may have had their original factory chips replaced with aftermarket performance chips.
We have found that incorrect software configurations can cause drivability issues, particularly during cold starts and idle.
To ensure we supply the correct replacement DME, please inspect the EPROM chip inside your original unit before placing your order.
How to Identify Your EPROM
The DME is located under the driver's seat.
Carefully remove the cover to locate the EPROM chip on the circuit board.
Check the label on the EPROM and determine which of the following applies to your vehicle.
Original Factory EPROM
If your DME still has its original factory EPROM, read the software number printed on the chip's label.
Select the matching factory EPROM number from the available options when placing your order.
Your replacement DME will arrive with the corresponding factory software already installed and ready for use.
Aftermarket Performance Chip
If your original DME has an aftermarket performance chip, follow the steps below to identify it.
Carefully lift the label to reveal the part number printed on the EPROM.
Once you have identified the EPROM type, select the matching option when ordering.
We will supply your replacement DME configured to accept the selected memory type.
What You Will Receive
Your replacement DME will include a factory software chip already installed, allowing you to operate your vehicle using factory software.
The DME will also be configured so that you or your technician can replace the supplied factory chip with your existing compatible performance chip.
IMPORTANT: Performance Chip Installation
We do not supply, transfer, or install aftermarket performance chips.
If you wish to retain your existing performance software, you or your technician must remove the performance chip from your original DME and install it in the replacement unit.
Selecting either performance option only determines the memory configuration of your new DME. It does not include a performance chip or performance software.
If you are unsure which chip you have, please contact us before ordering.
