Good day,
An FC3S RX-7 that has the ABS removed but still has all four wheel speed sensors, they are a Passive - Inductive type sensor.
I I understand this as the teeth pass the sensor the sensor generates an Alternating Current (AC) Sine Wave.
In this case I will be using an EMTRON Shadow 8 to connect these to in order to enable launch control, and traction control, and maybe even Cruise Control.
I Know that DI 1-4 have the built in Oscilloscope, so my plan was to connect those for each wheel speed sensor, the other lead of the sensor should be connected to ground, but not sensor ground (Ref)? This way I can use the Oscilloscope to tune the signal as required.
As for the setup of the actual sensor in EMTRON -
Sensor Type: Magnetic
Active Edge: Both (because a sine wave is both above and below datum?)
Pull Up: none
Scalar: Number of teeth / wheel diameter (of the tone wheel?)
Channel Assignment: which wheel the sensor is on.
I have done quite a bit of research on this, and the best I can come up with was this;
EMTRON Magnetic-Resistive Sensor WiringWhich was helpful, but did not answer the questions highlighted here.
Any clarification of red text or anything that I may have incorrect would be greatly appreciated, Thanks!
