Hi folks, the mrs bought a crank sensor bracket for a yb off eBay but what came attached to it wasn't a yb crank sensor, it had an alloy adaptor bolted to it with an e30 etc bmw crank sensor, im just intrigued at what it was used for, im presuming an aftermarket management maybe but maybe folks on here could shed some light

This is it



This is how it fits

 

It is as you say, a crank sensor adapted to fit.

It may work fine with the standard Cossie management, or it may be better suited to a different ecu.

 

Looks like a cossie and sensor to me. I wonder if it's been used as a speed sensor.

 

I thought it looked like an abs sensor but it has a rectangular 3 pin plug and the part number is e30 crank sensor

 

Fook knows then.
