PS10: INJ Flow

Injector Flow Override. PS10 may be used to fire each injector for a specific period of time thereby comparing injector flow. The following conditions must be met to override the injectors:

If the above conditions are not met, fuel injector override will be suspended until these conditions are met at which time the override will resume with injector No. 8.

When PS10 is first selected, the display will alternate between "--" for one second and "08" for five seconds ("08" signifying injector No. 8). Once PS10 is selected, the COOLER button is used to select the injector to be tested and the WARMER button is used to fire the selected injector.

Pressing the COOLER button will decrement the display and the injector number selected for testing from No. 8 through No. 1 and back to No. 8 again (injector number corresponds to cylinder number). Pressing the WARMER button fires the selected injector. While the injector is fired, "99" will be displayed. PS10 will only allow each injector to be fired once between engine runs to avoid flooding.
