ComSync EFI – One box does it all!

The ComSyncEFI system is unique in that it offers complete engine management in one system.  It includes electronic fuel injection, ignition control, 8 wide band O2 sensors and complete data logging.  The ComSyncEFI system has the ability to prevent burnt pistons by sensing the exhaust gas temps and if a cylinder burns hot it will automatically richen that hole, but if it senses a higher than normal EGT for six engine cycles it turns the fuel and spark off for that cylinder.

  • Assured high quality and dependability
  • Engineered to high standards
  • Tested under extreme conditions
