7. MSD Interface

Racelogic multiple spark discharge (MSD) traction control works with the crank signal

feeding the MSD unit. Usually there will be two wires from the crank sensor to the

MSD unit, one will be connected to GND and the other will carry the crank signal,

See Diagram 14.

Diagram 14 – Signals To An MSD Unit

7.1 Connecting the MSD Cut

The signal wire feeding the MSD unit should be cut and the Traction Control Ignition

cut interface should be connected as in Diagram 15.

We highly recommend that the traction control should be interfaced with the car using

connectors so that the car can easily be returned to run as standard. This can be

done using a ‘bullet’ type connector.

• Cut the signal wire on the crank sensor at a convenient position.

• Remake the connection with connectors.

• Connect the appropriate connector to the traction control wiring to connect the

traction control.

7.2 RPM

The RPM signal will be taken from inside the MSD, so no extra connections will need

to be made.

NOTE - The cylinders value in the traction control may need to adjusted to get the

correct value.
