Connecting the ECU

Communication Cable

The Emtron proprietary communication cable translates standard high speed Ethernet to a Lemo connector that feeds directly into the ECU header.  

The pin configuration for the Lemo receiver is as follows.  

SL series 

Green/White         –         B31 (TX+)

Green                 –         B32 (TX-)

Orange/White        –         B33 (RX+)

Orange        –         B34 (RX-)

KV series 

Green/White         –         D23 (TX+)

Green           –         D24 (TX-)

Orange/White        –         D25 (RX+)

Orange         –          D26 (RX-)

IP Config

The Emtune software will communicate to the ECU over a static IP address.  

Set your IP and subnet to the following on the Ethernet port you will be using on your PC. 

IP                             : 192.168.1.50

Subnet                 : 255.255.255.0

With successful connection, the Emtune Welcome screen will display “ECU DETECTED” in blue in the bottom left corner as can be observed in the background in the above example.
