EICS combines key components – ignition system (powered by FW Murphy’s IntelliSpark® ignition technology), air/fuel control, speed governing, interface and diagnostics, sensors, harnesses, catalyst and engine control unit (ECU) – in one package, saving you money and man-hours associated with the installation and setup of separate engine components.

The EICS has been pre-configured for your convenience, ensuring your engine will run at optimum performance without the need for manual field adjustments. Its D-EPR valve accommodates wide variations in fuel composition and speed/load ranges, maintaining efficiency with load following technology for even the toughest gas lift applications.

In addition, the EICS eliminates the need for pretest site visits by maintaining emissions – saving you time and money. With EICS you can be certain your site will pass required testing, like Quad J testing, without the need for pretesting to get dialed in.


  • Integrated system = simplified installation compared to separate components
  • Integrated approach makes more advanced diagnostics possible
  • No more setup of generic boxes – EICS is engine specific
  • No more dialing in – it’s pre-calibrated
  • Optimization of your engine’s performance
  • Maintains emissions compliance between testing – no tweaking necessary
  • Eliminates magneto failures and premature spark plug changes
  • Reduces engine failure diagnostic time
  • Reduces costs associated with the engine’s operation
