Traction control using factory 2 wire abs sensors

Postby Ms36262cobaltLS » Fri Apr 01, 2016 10:28 pm

Ok I have a 06 cobalt with a ms3x ecu I'm trying to look into traction control I have factory 2 wire abs sensors I was thinking using the rear wheels for a VSS signal and using the front hubs for wheel slip but as far as I know it's AC and the ecu can only read DC I need some ideas and information to what I can do I have herd maybe trying to run a HAll sensor for wheel speed but not entirely certain how I would mock up a wheel hub trigger wheel for the sensor I'm trying to build a good drag setup car so traction control, rolling anti lag and eventually I need to figure a way to do boost by gear and build something to tell ecu what gear car is in

Google LM2917 which is a frequency to voltage converter chip. This will take your AC signal and convert it to a DC voltage proportional to your wheel speed.
Download the application notes as they have some good circuit examples.

For MS3, just get some VR conditioners like the dual VR board sold by JBPerf.com.
