Hall or Magnet for traction control

Post by mark220475 »

Hello all

I am after some information on using the traction control function on the S100 ECU.

I am putting a V8 into a MX5, the MX5 has ABS on all four wheel using magnet sensors.

I would like to use the traction control function on the S100 ECU. Do I have to install four hall affect sensors with sensor rings or can I tee off the ABS magnet sensors and feed the signal into the ECU.

I do understand that a magnet sensor out puts a positive sign wave and that a Hall effect sensor outputs a square wave sign. But does the ECU require the square wave or will it work on of sign wave?

Cheers

Hi Mark

You need a square wave from a Hall effect sensor.
There is a converter made by Siemens that I used on my car:

Whether or not you can split the orginals, I don't know.

Often tying multiple devices onto a VR sensor....especially ABS...the ABS computer will not be happy.

Although the little Siemens piece Vauxhall use, may well be insignificant enough that the ABS might not notice.

ABS rings also tend to have a lot of teeth.....so check there are not too may to give a functional output for the DTA
