The VAC S14 Crank Trigger Kit is the best choice for running an aftermarket engine management system on your BMW...
The VAC Motorsport trigger wheel 'clamps' onto the back of the factory S14 crank damper providing one of three (or custom ordered) trigger wheel outputs compatible with any conceivable ECU setup.
This fashion of mounting has proven itself on street and race engines and does not require pressing, drilling, or tapping of any kind. This ensures that you have a problem free install and that the trigger wheel will not vibrate itself out of true or warp the damper while installing like other trigger wheel setups.
Striving for the ultimate in reliability and quality, a aerospace-grade sensor is used in place of
all to common Delco or BMW sensor others have tried.
This ultra high-grade sensor was found to be infallible even under the strenuous heat and vibration S14s put on their accessory, this cemented itself as a standard part of the kit
and a favorite of our customers. (this small company is actually a suppler to
NASA, hence why the sensor is so good and the kit a little more costly than what
you would expect, but we feel its worth it)
Our kit is complete with our CNC aluminum adjustable sensor bracket. This bracket mounts directly to the block, and allows precise adjustment for the sensor so even the most particular ECUs get the trigger signal they are looking for.
Whether you are "doing-it-yourself" or a professional racer this kit allows easy reliable attachment of a trigger wheel of choice plus included precision sensor and bracket.
As one customer put it, our kit is "Simple, rugged, foolproof."
Kit is supplied with:
- VAC Crank Trigger Wheel (60 -2, 36 -2, or 12 evenly-spaced)
- VAC Adapter Ring
- Aerospace Grade Magnetic Crank Sensor
- VAC CNC Aluminum Mounting Brackets
- Hardware
*36-2 is typically the most popular wheel for the S14 with most ECUs. This is the recommended wheel for the KMS kit as well*
VAC Tech Notes:
Both VAC and now MoTec recommend 12 evenly-spaced for MoTec ECU installs on S14s. It is also imperative to mark the location of the set screws on the crank pulley, spot drill them, and then retain the screws with blue loctite.
