In the SAFC, the input airflow signal is converted into an air volume value and this value is corrected by the air correction factor.
As an output signal, the corrected air volume value is converted back into an airflow signal and then this signal is output to the elec- tronic control unit ECU. It can also be set according to the throttle opening level. Final number Correction area increase amount. Correction engine RPM. Correction area Decrease amount Throttle opening The graph, at selection, is dis- played as a highlight display.

The actual display is shown in the lower left figure. The screen is scrolled by pressing the left or right part of the center switch. If either the upper part or the lower part of the center switch is pressed during the ordinary display, this display is changed into a reduced display as shown in the lower right figure.
In this case, all setting graphs are displayed on a single screen. The reduced display can be changed into the ordinary display by pressing either the upper part or the lower part of the center switch.

Select [TH-Point] in the setting menu. Select Select Go back. When the rotary switch is turned clockwise, the numeric value is increased.
Select [Ne-Point] in the setting menu. The same can be said for the other revolution points,. The selected item is displayed as a reversing display. When the rotary switch is turned clockwise, the cursor is moved upward. When this switch is turned counterclockwise, the cursor is moved downward 2 Set the engine RPM Select an engine revolution point and press the right part of the center switch to set the engine RPM.
When the upper or lower part of the center switch is pressed or the rotary switch is turned counterclockwise or clockwise, the numeric value is increased or decreased. In this case, engine stall can be prevented by using the deceleration air upper limit setting.
With the deceleration air upper limit setting, an upper limit is given to the airflow output voltage at the engine RPM set at Ne01 and Ne02 Ne01 and Ne02 of Ne-Point below the Thr throttle opening.
Select [Dec. When the rotary switch is turned clockwise, the cursor is moved up ward. Explanation of Function This unit takes the input air flow sensor signal and modifies the signal to show volumes of air which can be controlled by adjusting the RPM Specific Adjustment Volume on the front of the unit. The unit then translates the newly adjusted air volume amount to the corresponding air flow sensor signal and sends the information to the engine control unit.
Because the engine control unit calculates optimum fuel amounts according to air flow signal input, the air flow volume and fuel amounts will remain almost perfectly proportional. With the S-AFC, the air flow signal may be adjusted according to specific RPM ranges by using the 5 adjusting volumes on the front of the unit.
Adjusting each of the volume knobs on the front of the unit will allow setting of the RPM ranges. When the volumes are set in the positions below. Infiniti Q45 Type Select 6. Logout [ google [bot] ].
