Early 944 Sport DME
It has always bothered me that I could not accept an early style Bosch DME (ML2) as a core for my late model (ML3) DMEs, and this is what I came up with. While it looks very different from my current Sport DME products, it is actually nearly identical. On the electronics side, the main difference is I designed a new flywheel sensor circuit to replace the S100 flywheel sensor chip that is not present in the early ML2 DME. For the enclosure, I am using an off-the-shelf extruded aluminum body and custom 3D printed adapter for the 35pin system connector. It is specifically designed to be a direct-fit replacement that will mount in the early 944 factory location without modification. That said, it is still a late model ML3 DME, so you must update the AFM to Bosch 0 280 202 064 or upgrade to a Lindsey Racing MAF kit. The only parts needed out of the ML2 DME are the Injector Driver microchip and the spring clip that retains the 35pin System connector. Everything else in this DME is brand new!
The above picture shows what the circuit board looks like. All electronic parts are brand new except for the injection driver microchip that must be reused from the early 944 core DME..
The side-by-side picture above shows the outline of the new DME compared to the the original Bosch ML2 944 DME. the Mounting holes near the connector are designed to be in the exact same postion as the original. The F9T DME is also 1.3lbs (590g) lighter than the original Bosch DME.
The 3D printed adapter perfectly mates to the factory 35pin system connector. The spring clip retainer is the only other recused part from the original ML2 DME core.
The F9T DME is designed to match the outline of the early 944 ML2 DME, however it is slightly taller.
Shown above is the back of the F9T “Early” 944 Sport DME. All F9T DMEs are faithfully based on the factory Bosch ML3 design and therefore have an FQS (Fuel Quality Switch) just like the Bosch equivalent.
