Electrical

"Plug and Play" by definition. No cut wires.

Background

By the 996 generation Porsche was owned by VW and shared engineering and a parts bin alongside Audi. One major benefit to this shared engineering is the electrical systems, and their compatibility. Both the M96/M97 and the Audi 2.7t use Bosch ME7. This means the 2.7t engine and car can seamlessly integrate with some ingenuity and micro-controlling!

One key difference between the two brands is that the Audi's ECU (engine management) is built directly into the engine harness. On the Porsche the DME (engine/body management) is incorporated into the body harness.

Engine Management, Custom DME Hardware, Direct Plug in Harness

In our design, engine management is handled natively by the 2.7t ECU. These ECU's are fully programmable and support: map switching, launch control, 2 step, and no lift shift.
The marriage between engine and chassis happens at the Porsche DME; it gets replaced by our DME.
The RennDME handles the drivetrain logic, DAC/ADC/CANBUS and re-engineers part of the cars electrical system to support the 2.7/4.2 engine needs. It mechanically fits in the same location as the Porsche DME, utilizes the same connectors, and mounts using the same screws.
To integrate the engine harness with the chassis we convert the Audi engine harness connectors to the Porsche style round connectors. The Audi ECU mounts on our bracket and sits atop of the intake manifold.
Finally the engine harness plugs in at the factory Porsche connector station. Everything is retained with our design; tachometer, oil pressure gauge, accelerator pedal, logic based fan control, Air conditioning, ABS, and even cruise control, all without having to cut a single wire on your chassis.
