Important
A spool auto-calibration must be executed for effectuating the change in the Valve Calibration Data sector.
In this case the below parameters shall be configured (shown with default values).
P3091 set to -420 for OSPE/EHI or -700 for EHPS, P3093 set to 420 for OSPE/EHI or 700 for EHPS and P3095 set to 25.

Fine-tuning of parameters for spool calibration

The operator can tune the following parameters when the calibrated dead-band values give, either in Auto-guidance-
or quick steering-mode, a sluggish steering behavior, aggressive steering behavior or simply if the total calibration
time is too time-consuming.
Sluggish steering behavior after successful dead-band calibration
The operator should try with a smaller time frame (P3806 and P3808 should be decreased) and the measured
wheel angle distance should be increased (P3804).
Aggressive steering behavior after successful dead-band calibration
The operator should try with a larger time frame (P3806 and P3808 should be increased) and the measured
wheel angle distance should be decreased (P3804).
Total spool calibration time is to long
The operator should try with a lower vector combination (P3810 and P3811 should be decreased) and the
time frame (delta between P3806 and P3808) and measure wheel angle distance (P3804) should be decreased
percentage-wise, equally.
