NOTE:  The communication channel built into series 114 ignitions is not required for  most common setup and tuning functions.  Operators are encouraged to address those needs with the simple configuration tools outlined in the manual before considering this utility (via EICAD or other third party tools).   “Keep it simple” is a long-standing aviation principal.

Contact E-MAG if you need a copy of our EICAD interface.  It’s a PC (serial port) based demonstration program only – not intended as a permanent built-in feature and has not undergone testing or upkeep for it to serve such purpose.  Documentation and support will be sparse.

• A Configuration Resource
  • Tach signal can be set for one or two pulses per revolution.
• An Operational Resource
  • Advance Shift is a control that shifts the ignition’s advance curve up and down (within preset limits).  (NOTE: Negative Advance Shift values will not display accurately – avoid using negative values or call if you need assistance.)  You can:
    • Monitor the current Advance Shift and the current (moment to moment) firing angle (degrees BTDC).
    • Change the Advance Shift setting while the engine running in order to dial in your preferred setting.
    • Store your preferred Advance Shift setting.  Storing a setting will overwrite and replace the factory default Advance Shift.
  • Status and Reporting
    • Firing angle.
    • RPM – This is a serial based signal, separate and apart from the tach output that is available on the connector plug.
    • Ignition firmware version.
    • RPM Limit- Your max rpm safety limit.  Above this rpm the ignition will suspend firing plugs.
    • Maximum Advance. A ceiling you set that will cap the maximum advance firing angle, no matter what value may be used for Advance Shift.
• Installation
  • Requires USB to serial adapter-not provided and hand wiring to ignition control plug.
  • Connect your ignition to the serial port of your lap top or other serial device (three wires: transmit, receive, and ground) to E-MAG’s control plug. A connection diagram (see below) appears when you click the “Connection Info” button on the EICAD screen.

Note: 

1. The data leads (terminals 2 and 3) need to be shielded.  This shielding can also serve as the ground connection between the ignition (terminal 1) and the serial connector (terminal5).

2. The ignition needs to be powered (12 volt) ON in order for EICAD to interact. You may need to select the appropriate COM port on the EICAD screen, depending on which version of EICAD you are using.
