The dual sensor unit, no pulley is for people who might be upgrading from another crank sensor kit, and have a trigger installed. So long as the trigger wheel diameter is between 127mm and 132mm in diameter, then our kit can most likely be used with the existing trigger wheel.
Dual sensor
Trigger every 720 degrees (compression stroke)
36 tooth trigger wheel
Dual sensor – This unit has the same sensor as the in the body as the single sensor, but a second sensor that points at the trigger disc mounted to the Adapt Motorsport crank pulley. As standard, this is a 36-1 pulley, meaning that it has 36 teeth, minus 1 missing tooth. This allows the ECU to know what the crankshaft position is at all times and in combination with the internal sensor, whether it is on the compression or exhaust stroke in its 720 degree cycle. This system provides a complete engine position sensing kit. If you have an existing 36t trigger disc, it is possible to use our sensor kit on this, provided that the teeth are designed for a hall sensor, and not a magnetic sensor, and the outside diameter of the teeth is between 127 and
130mm. Please contact us for clarification
Why do you need this system and what are crankshaft/camshaft position sensors?
When converting classic Porsches to modern electronic fuel injection, the engine control unit (ECU) needs to know exactly where the crankshaft and camshafts are in there 4 stroke cycle and how fast they are spinning. This allows the ECU to correctly time each spark and fuel injector opening time and duration. The first 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 a 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 centre (TDC), it does not know if it is on the compression or exhaust stroke. This is where the second 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.
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.
Sync 2 Kit Includes:
Main body assembly
ZF Hall effect sensors x 2
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)
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 2.7lre, 3.0ltr and with the turbo distributor gears.
Please Note
2.7 engines may need to trim some of the crank case near the crank pulley to prevent interference.
