These trims can be used to correct a surging idle that results from mechanical loads being switched on.
Note: These settings are only available when using traditional fuel equation mode.
Air Con Trim is amount of time in milliseconds added to the injector pulse width when the Air Conditioning clutch is engaged and Idle Speed Control is Active, if Idle Speed Control is turned off then the engine speed must be below 2000rpm for this trim to be active.
Drive Trim is amount of time in milliseconds added to the injector pulse width when the transmission is in a driving gear and Idle Speed Control is Active, if Idle Speed Control is turned off then the engine speed must be below 2000rpm for this trim to be active. Any Gear other than 0, -, N and P are considered to be driving gears and the clutch and Neutral Park switch affect the In Driving Gear Status.
Engine Fan Trim is amount of time in milliseconds added to the injector pulse width when the engine fan is activated and Idle Speed Control is Active, if Idle Speed Control is turned off then the engine speed must be below 2000rpm for this trim to be active.
GP Idle Fuel Trim is amount of time in milliseconds added to the injector pulse width when the GP Idle Input is activated and Idle Speed Control is Active, if Idle Speed Control is turned off then the engine speed must be below 2000rpm for this trim to be active.
PS Idle Fuel Trim is amount of time in milliseconds added to the injector pulse width when the PS Switch is activated and Idle Speed Control is Active, if Idle Speed Control is turned off then the engine speed must be below 2000rpm for this trim to be active.
