Why do you need this system and what is a trigger or ref/sync? 

When converting classic Porsches to modern electronic fuel injection, the engine control unit (ECU) needs to know exactly where the crankshaft is in its 4 stroke cycle and how fast it is spinning.  This allows the ECU to correctly time each spark and fuel injector opening time and duration.  One sensor is pointed at the crankshaft pulley and measures a pulse for every tooth.  There is one missing tooth, and from this the ECU can work out what the crankshaft position is relative to this missing tooth.  The time between pulses gives the engine speed and rate of change.  But, there is one problem, the engine spins two complete revolutions to complete its 4 stroke cycle.  So whilst with this one sensor, the ECU knows where it is relative to top dead center, it does not know if it is on the compression or exhaust stroke.  This is where the reference sensor comes in.  This sensor is installed in the body our module, and measures a single tooth.  As this is installed in the distributor hole, this is geared to run at half engine speed, so will produce a pulse once every 720 degrees.  With these two sensors, the ECU knows the exact position the engine is in its 4 stroke cycle.  And now, we can run accurate sequential injection and ignition.

Our kit uses high speed digital hall effect sensors for a digital output to the engine control unit, these are best run at 8V, most modern ECU's have an 8V output dedicated for crankshaft sensors, but can also run at 5-12V.

Machined aluminium housing and anodised finish, complete with maintenance free bronze bush and sealed for life roller bearing.  These sensors are quite adjustable so are often able to be used with existing crank pully and trigger wheel setups from other quality vendors.

Our systems are available in 3 configurations.

  • A complete engine position trigger kit, with crankshaft pulley and 36-1 trigger wheel, or
  • A trigger kit with two sensors and no crankshaft pulley or trigger wheel, which may fit other aftermarket crank pullies, or
  • A trigger kit with internal single sensor for crankshaft reference position for those that already have a crank sensor on the flywheel to measure crankshaft position wish to run sequential ignition/injection. It behaves similar to a "Cam Sensor" in that it produces 1 pulse every 2 engine revolutions.

This kit replaces the distributor, so requires either coil on plug, or other single coil lead per cylinder where the ECU determines ignition events.

Kit Includes:

Sync 1 Sensor

  • Main 1 sensor body assembly
  • 1 x ZF Hall effect sensors, single tooth for engine cycle sensing
  • Wiring and connectors, with pins and connectors for connecting to your wiring loom.
  • For use when you already have some other crankshaft position sensing either on the flywheel or pulley and just need to add an engine cycle/sync sensor to complete your sequential system.

Sync 2 Sensor

  • Main 2 sensor body assembly
  • 2 x ZF Hall effect sensors
  • Wiring and connectors, with pins and connectors for connecting to your wiring loom.
  • For use with other crank trigger systems.
  • (We can not guarantee that that this system will fit every crank/trigger system, however it can be easily modified to suit most systems)

Sync 2 Sensor + 127mm Crank Pulley + 36-1 Trigger

  • Main 2 sensor body assembly
  • 2 x ZF Hall effect sensors
  • Wiring and connectors, with pins and connectors for connecting to your wiring loom.
  • 127mm Crank Pulley and Trigger Disc to suit parallel end crankshafts.

Sync 2 Sensor + 127/90mm AC Crank Pulley + 36-1 Trigger

  • Main 2 sensor body assembly
  • 2 x ZF Hall effect sensors
  • Wiring and connectors, with pins and connectors for connecting to your wiring loom.
  • 127/90mm Crank Pulley and Trigger Disc to suit parallel end crankshafts, suits early AC cars.

Sync 2 Sensor + V Rib Belt Conversion Kit

  • Main 2 sensor body assembly
  • 2 x ZF Hall effect sensors
  • Wiring and connectors, with pins and connectors for connecting to your wiring loom.
  • V Rib Crank Pulley and Trigger Disc to suit parallel end crankshafts.
  • V Rib Fan Pulley
  • Eccentric Idler Pulley Kit
  • V Rib Belt
  • Check out the product listing for the V rib conversion kit for more details, this kit requires a 3.2 engine console to clear crank pulley.

This replacement kit fits to the OEM distributor location using your own factory distributor gear. Simply remove the factory distributor gear from your install the gear, wire to your ECU, fine tune the sensor air gap to the crank trigger disc, setup the reference position in the ECU and you have all the sensing you need for the latest sequential fuel and ignition systems.  This kit works on the 2.7, 3.0, 3.2 and with the turbo distributor gears.

This kit does not work on 964/993 3.6 cases, however we offer a separate cam sensor for 964/993 3.6 cases.
