Function sailing [SGL_ENABLE] disabled at 149084 (8bit) by setting zero

I'm working with the DQ500/381 DAMOS files floating around.
There is one in this "Merry Chrismas package" (thanks _nameless  )

I have no FR, I'm only assuming with the DAMOS description.
In my case SGL_ENABLE is set to 3 (bit 0 + 1)

The sailing part has quite a lot of enabling/disabling switches, I'm using these ones as well:

SGL_MIN_V_EIN  1490BA (16bit HiLo) 7x1 'above this speed[km/H] sailing is activated'
SGL_MIN_V  1490C8 (16bit HiLo) 7x1 'below this speed[km/H] active sailing is left'
SGL_MAXIMAL_BIS_V  1490D6 (16bit HiLo) 1x1 'above this speed[km/H] no sailing is allowed'

yes, sailing means 'off throttle', clutches are open (display is showing 'D' without gear position) and engine is idling.

Very annoying not having the used engine braking thrust and wasted shifting(throttle blips) back in gear means additional wear.
In theory should be saving fuel, but not measurable for me.
