My hall effect sensor is bunk. My car came with a racepak which was getting driveshaft RPM with a clamp on the driveshaft (with a magnet) and a hall effect sensor on a bracket. The racepak takes standard square wave input. Any links to cheap weather proof sensors that "should" work? I already tried wiring up an NB transmission sensor but it's some odd sort of inverted pluse wave and dosen't work. I only need the sensor not the clamp for the driveshaft since I have that already.

 

I'm not sure if something like this should work?

Try DIYautotune's hall effect sensor. Inexpensive. They have a threaded one too which makes brackets simple.

 

Thanks... I don't know why I didn't think to check there!
