Hardware installation

To guarantee that the system functions properly, it is of utmost importance to adhere to the
instructions given below.

5.1

Fitting the ECU

It is important that the ECU should be fitted in a dry and not too hot place.

5.2

Connecting the communication cable

Attached to the included wiring loom of your KMS IB/IA23 system is a serial port. You can use this
communication for you desktop/laptop and make a connection with the KMS Ignition software.

Warning:

Be sure what kind of ignition coil you have. Is this a coil without
amplifier, use the thicker wires of the ECU. If you have a coil with
amplifier it’s important to use the thinner connector wires.
