How can we use the Traction Control Features of the MoTeC?
There are several ways to utilize Traction Control. Ultimately we need at least 2 inputs for wheel speed connected to the ECU. We can either run these 2 inputs directly to the 2 digital inputs the ECU has or we can use a Traction Control Multiplexer (M TCMUX). The TC MUX allows up to 4 wheel speed channels to be sent to the ECU using only 1 ECU input channel. This allows better sensing signals and allows the additional switched input to the ECU to be used for a separate function as desired. The TC MUX requires 8 V and 0 V supply from the ECU and its output is connected to the ECU’s Digital Input 1 or 2. Then the Hall Effect Sensors can be connected to the TC MUX directly and they can measure wheel speed or shaft speed. The Sensors do not require a magnet to trigger so they can be easily adapted to read the bolts holding a sprocket or a brake rotor. For the best results especially at low speeds, a minimum of 12 teeth per revolution is desired.
