Update your failure-prone 30+ year old factory Bosch DME with this modern direct-fit replacement!

The Focus 9 Technology SPORT DME is an upgrade for the factory BOSCH ML3.1 Motronic computer. Unlike universal aftermarket computers, installation is simple and requires no additional sensors, tuning or other modifications. While it looks different internally, it functions identical to the original Bosch DME in every way right down to the FQS switch. This is because the SPORT DME reuses four key microchips from your original DME which preserve the core functionality of the original Bosch DME. In this way, all performance chips, MAF kits or other upgrades made for the factory DME are compatible. By reverse-engineering the factory Bosch DME, we updated the electronics around these chips using 21st century electronics and design practices. This, in effect, is the equivalent of removing the brains from your old tired DME and giving it a brand-new body. In doing so, we corrected fundamental issues that plagued 944 owner for decades.

Built with chip swapping and universal fitment in mind, the new “SPORT” DME offers the following additional new features in comparison to the original “Standard” F9T DME.

Center Point Lid Mount

No more bending and braking tabs to open the DME cover when swapping performance chips. Our Center point mounting system opens the DME easily in seconds with just a Philips screwdriver.

24pin/28pin Chip Select Switch

You no longer have to choose between 24 or 28 pin compatibility. Simply insert which ever chip you like, then set the selection switch mode.

Naturally-Aspirated/Turbo Select Switch

A 944 and 951 DME in the same product! Simply insert the desired chip, then set the NA/Turbo switch to the corresponding mode. For the Turbo 944, this switch has the added benefit of diagnosing a failed KLR no-start issue. Just set the ignition mode to “NA” to bypass the KLR ignition knock control. If the engine starts, then the KLR is your issue.

*** Do not operate a 944 Turbo in NA mode because the knock and detonation protections are disabled. This feature is for testing purpose only with absolutely no boost pressure applied to the engine at any time.

OBD Module Ready

This DME is designed to accept the F9T OBD+ Upgrade module. It has provisions built into the circuit board that support mounting and sensor connections. More information about upgrading to all On-Board Diagnostics can be found using the link below:
