3. Only after unplugging the ignition module and removing the fuses, load the M130 Package.

Note: Lambda measurements require a MoTeC Lambda-To-CAN (LTC) device and Bosch LSU4.9 Lambda Sensor. Before installing the LTC, it MUST be pre- configured to 500kbit/sec CAN bus speed.

Unused provided plugs

1. DTM4 connector Lambda for connection to the optional LTC.

2. DTM2 connector Power Retain used to maintain ECU power wile programming.
   Note A bridging connector can be made to join terminal 1 and 2 of the DTM2 for the Power Retain function.

DSP Knock Control Update for Revision B Adaptor Looms.

The April 2013 firmware update provides for on-board DSP Knock Control out of the box.

Earlier kits using the Revision B Adaptor Loom (March 2012) can be modified to utilise this
feature.

If the April 2013 (or later) M130 firmware is installed on these earlier kits, the following
modifications must be made to avoid possible engine damage:

1. Install the April 2013 M130 firmware and obtain a new licence (issued at no charge).
2. Replace the “Knock” connector plug (DTM2 Male) with a DTM4 pin male plug, with the grey wire inserted into the pin 2 position, as shown in the image.

Alternately, make a jumper cable to connect pin 2 of the “Knock” connector (DTM2 Male) to pin 2 of the “Knock SKM” connector (DTM4 Female)
