VG30DE(TT) Crank Trigger & Cam Sync for ATI Dampers

A VG’s Ignition timing accuracy can be erratic with the stock CAS due to timing belt stretch and inherent harmonics that occur between the crankshaft and camshafts. Moving the critical trigger points to the crankshaft completely eliminates these problems and ensures the ignition timing programmed into your ECU is exactly what is delivered to the spark plugs.

Crank Trigger Wheel

What’s the difference between 12 and 36 tooth? Click here to learn about crank trigger tooth count.

• available in 12+1 tooth* or 36-1+1 tooth** configurations
• 100% CNC machined for the highest accuracy of tooth edge and location
• electroless nickel plated for corrosion protection
• designed to bolt-on to either ATI^® Race or Street type dampers*** for the VG30DE(TT), NO MODIFICATION TO THE DAMPER IS NECESSARY

*12+1 tooth crank trigger wheels will work with any aftermarket ECU, but in particular, a 12 tooth crank trigger is the only crank trigger that will work with a Haltech Platinum Pro^® Plug-In ECU for the Z32 (PN: HT-055107).

**36-1+1 tooth crank trigger wheels can be used on AEM S1, S2, and Infinity^®, Haltech Elite^® or similar higher-capability ECUs.

***The ATI^® VG30DE(TT) Race and Street dampers feature different bolt patterns, PS pulleys, and PS pulley locating hub diameters. But BDE trigger wheels can accomadate either damper by simply flipping the trigger wheel to the side appropriately labeled.

Why make it only work with the ATI^® Dampers?

The ATI^® design sets the bar for torsional dampers that all others only dream to achieve – It just makes sense to design a VG crank trigger to work with the best damper available for the VG platform.

Power Steering Pulley

The original ATI^® PS pulleys cannot be used or modified to work with the BDE crank trigger wheel, but BDE has you covered – we have designed optional replacement PS pulleys which retain the correct belt alignment. Some additional features are:

• Choose from 3 rib or 4 rib configurations to work with your PS pump pulley.
• Both pulley’s diameter is the same as stock PS belt and work with a 365mm length.
• multiple bolt patterns to allow use on Race damper or Street damper
• works with existing ATI^® PS pulley bolts
• No crank trigger?… No problem, use BDE-320 to adapt either BDE-317 or BDE-318 to your ATI damper.

Cam Sync and Mechanical Fuel Pump Mount

A cam sync reference signal is required for coil on plug and sequential injection to inform the ECU that the engine is approaching TDC for the compression stroke. The BDE cam sync system uses the same type Hall Effect sensor as the BDE crank trigger plus the option to mount and drive a mechanical fuel pump (3/8″ hex drive) is built-in and ready to use whenever you are. The BDE cam sync hub is electroless nickel plated for corrosion protection and balanced to offset the weight of the trigger tooth.

Hall Effect Sensors

• Stainless steel body with M12x1.0 threads
• Deutsch connectors are installed, ready to plug in and go
• pull-up resistor is built-in to the sensor (if your ECU is equipped with internal pull-up resistors, turn them off with the software)
• Both BDE crank trigger and cam sync Hall Effect sensors are identical and interchangeable
