- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
Adapt Motorsport Sync 2 ignition reference and synchronisation sensor kit for Porsche 911 Carrera 3.2 models from 1984–89. This version includes a 127/133mm air-conditioning crankshaft pulley and 36-1 trigger disc for engines using the larger 3.2 AC pulley diameter.
Fits
- Porsche 911 Carrera 3.2 1984–86
- Porsche 911 Carrera 3.2 G50 1987–89
Visually confirm the crankshaft pulley and air-conditioning drive arrangement fitted to the engine. Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The kit provides a compatible engine control unit with crankshaft speed, crank position and engine-cycle synchronisation signals. One Hall-effect sensor monitors the teeth and missing-tooth reference of the 36-1 crank trigger, while the second reads a single tooth within the distributor-location module.
Because the module is driven at half engine speed, its reference sensor generates one pulse for every two crankshaft revolutions. The ECU can therefore distinguish between the compression and exhaust strokes, providing the position information required for sequential fuel injection and electronically controlled ignition.
Functions
- Measures crankshaft speed and angular position
- Supplies a missing-tooth crank reference from the 36-1 trigger disc
- Generates one engine-cycle synchronisation pulse every 720 degrees
- Allows a compatible ECU to identify the compression stroke
- Supports sequential fuel-injection and ignition strategies
- Fits in the original distributor mounting location
Technical Details
- Sync 2 body assembly with two ZF digital Hall-effect sensors
- 127/133mm AC crankshaft pulley and 36-1 trigger disc
- Pulley designed for parallel-end crankshafts
- Recommended sensor supply: 8V; supported range: 5–12V
- Machined aluminium housing with anodised finish, maintenance-free bronze bush and sealed roller bearing
- Wiring, terminals and connectors for integration with the engine wiring loom
Installation Requirements
The sensor body replaces the original distributor and reuses the factory distributor gear removed from the existing unit. Installation requires connection to a compatible ECU, adjustment of the sensor air gap at the crank trigger and configuration of the reference position within the ECU software.
As the distributor no longer routes the ignition spark, the engine must use coil-on-plug ignition or another individual coil-and-lead arrangement controlled by the ECU. The manufacturer states that this kit is not compatible with Porsche 964 or 993 3.6 engine cases, which require a separate sensor solution.
Why Replacement Matters
A sequential engine-management conversion requires reliable crankshaft and cycle-position information before the ECU can correctly schedule individual injection and ignition events. This kit combines both signals in one distributor-location assembly and includes the larger AC pulley required by 1984-onwards Carrera 3.2 installations.
FAQs
- Does the kit provide crank and synchronisation signals?
Yes. One sensor reads the 36-1 crank trigger, while the second generates an engine-cycle reference once every two crankshaft revolutions. - Can the original distributor ignition remain fitted?
No. The module occupies the distributor location, so ignition events must be controlled by a compatible ECU using coil-on-plug or another per-cylinder coil arrangement. - Is this the correct AC pulley for an early 2.7 or 3.0 engine?
No. This 127/133mm version is intended for 1984-onwards 3.2 engines with the larger air-conditioning pulley diameter. - Does the kit include wiring connectors?
Yes. Wiring, terminals and connectors for connection to the engine wiring loom are included.
