Hi everybody,
I'm working on the mounting of my wheel speed sensor and target and have some questions
Can you confirm what is the best expected signal for accuracy between 1,2 and 3 ? and the best ratio traveled distance / tooth (or frequency) for launch control's PID according to your experience ?
Thanks for your help.

Re: Wheel speed signal and target shape
1 is best.
2 should be fine.
3 is most likely to cause issues, but it depends on actual duty percentage.
All 3 should work unless you make the tooth or gap too small to be read by the sensor.

Re: Wheel speed signal and target shape
It will be first in this case.
With a 16 teeh target it give me a sensor frequency from 0 to 175 Hz for first gear top speed. Is it fine for the launch control loop ?
thanks

Yes, that will be fine.

Re: Wheel speed signal and target shape
16 pulses per revolution is a pretty good resolution. I only have 6 which means the wheel has moved almost 300mm between pulses; It does work but more pulses would be better.

Thanks
I need to make some drawings now

Re: Wheel speed signal and target shape
I'm using twenty pulses/revolution, with front targets mounted inside the brake bells.

Nice idea. Thanks for sharing.
No problem with the brake disc temperature and the sensor ?

Re: Wheel speed signal and target shape
This is good info. I plan to get ABS struts from a newer model of my car and use that.
