Injector rails

Rail switching mode

Specifies the mode for switching injector rails

You have to use relays for controlling the fuel rails supply. Relays are controlled with "Rail1" and "Rail2" output modes.

Off

Injector rails do not switch

Gas/petrol auto switching

Enables auto-switch mode. Start on petrol, then switch automatically to gas. If gas tank is empty - switch back to petrol.

External switch can be used to force operation on petrol.

External LED can display current operating state.

  • Petrol - Calibrations Set #1
  • Gas - Calibrations Set #2

By outputs Rail1/Rail2

Rail switching rules are set in output settings.

  • Rail1 uses injector parameters from Calibrations Set #1
  • Rail2 uses injector parameters from Calibrations Set #2

With calibrations

Rails are switched together with the calibration sets

  • Rail1 uses injector parameters from Calibrations Set #1
  • Rail2 uses injector parameters from Calibrations Set #2

Second row of injectors on INJ5-8

EMS-2 on 2-4-cylinder engines allows you to connect a second row of injectors (or gas injectors) to four free outputs INJ5-INJ8.

Gas/petrol changeover

This is where the gas/petrol auto switching settings are adjusted

The start takes place on petrol, when the specified temperature is reached, the gas valve turns on, and in a couple of seconds the engine switches to gas.

When the gas pressure drops significantly, the engine switches to petrol.
