CONNECTING THE SECONDARY INDUCTIVE PICKUP
The secondary inductive pickup cannot be in contact with, or its connecting wire be
crossing other engine electrical wires or stray electrical interference may result.
1 Clip the secondary inductive pickup around one spark plug wire.
2 Route the inductive pickup cable to the RPM port on the DynoWare RT module
making sure the cable is clear of devices that produce electronic noise (spark plug
wires, coil wire, coil etc.).
Note: Inductive pickup placement is important. Position the inductive pickup so
that it is not making contact with any other spark plug wires. Separate the spark
plug wire from the spark plug wire bundle for proper operation.
Note: You must ground the vehicle to the dyno for the electronics to function
properly. Refer to “Grounding the Vehicle” on page 4-9.
