engine coolant temperature calibration sites as chosen for the warm-up enrichment
calibration table above.
P-S Fast idle inc
Post start fast idle increase.
Extra engine RPM above normal idle speed immediately after engine start.
Uses idle control valve to provide the higher idle speed.Calibration for idle speed
increases immediately following start-up. Decays away with time to warm-up fast idle
RPM calibration. Calibration range is O to 1020 RPM. This calibration uses the same
engine coolant temperature calibration sites as chosen for the warm up enrichment
calibration table above.
P-S FastIdle timeout
Post start fast idle time out.
Period of time after engine is started "Post start fast idle increase" operates for.
Uses idle control valve to provide the extra RPM. Decay time for post start fast idle
increase. Calibration range is 0 to 51 SEC. This calibration uses the same engine coolant
temperature calibration sites as chosen for the warm-up enrichment calibration table
above.
W-U accel enrich mul
Warm up acceleration enrichment multiplier.
Calibration multiplier for additional engine coolant temperature dependent acceleration
enrichment. Calibration range is 1.0 to 8.0 times the "warm" engine value. This
calibration uses the same engine coolant temperature calibration sites as chosen for the
warm-up enrichment calibration table above.
Do not change values until base fuel table is fully mapped.
W-U decal enleanment
Warm up deceleration enleanment multiplier.
IAC-proportion range
Idle air control proportion range.
To find range of valve select idle speed of 6000 RPM in "Idle speed table".
Record the engine RPM.
Example:- engine RPM = 3400
Next set idle speed to 100 RPM in "idle speed table".
Record the engine RPM. Example:- engine RPM = 600
To find the Range,
3400 - 600 = 2800 Range
Add 50 RPM to the Range to get the final value, 2800 + 50 = 2850 Range.
IAC-closed rpm value
The rpm that corresponds to the IAC valve at the closed position.
