Fabspeed DME Chip Upgrade for Porsche 911 Carrera 3.2 (1984–1989)

Match a replacement DME chip to the Carrera 3.2’s controller, market specification, fuel and engine modifications. This is an air-cooled chip application rather than an OBD-II handheld tune for later 911s. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.

Technical Details

• Manufacturer product reference: FS.POR.911.DME.
• Supports matching US catalyst-spec and Euro/ROW Carrera 3.2 configurations.
• US default calibration uses 91-or-higher octane fuel; request 93 specification if needed.
• Euro/ROW default is 95 RON; request 98 RON if appropriate.
• 1987 cars require checking whether the DME uses a 24-pin or 28-pin chip.
• Confirm DME/chip identity and programming before ordering.
• Published test used an 1987 car with a pre-muffler; it is not an untouched-engine guarantee.

Use restrictions

The calibration must retain required emissions controls. Fabspeed excludes requests to disable emissions equipment or its monitoring.
