What model are you using as a head unit? LCX-111C?

Which model of the LowranceNet do you have? 1st generation has Blue connectors, 2nd generation has red connectors..

Also Do you have the correct Evinrude cable?

From Lowrance's website..

Evinrude E-TEC Engines are configured by connecting a computer to the engine through a serial port and running a configuration program on the computer that sets up the engine. They cannot be configured by Lowrance gauges or head units.
