You want to cut spark before you cut fuel.

Lift your NMAX.

Read the maps you're editing and don't just throw numbers in because someone else did the same thing.  Try and understand what you're attempting to do.

You've lifted error detection to 7500 for no reason.

Read the FR.

The concept is entirely based around that.  Cut spark before fuel. 

ZUESZ in the Function Sheet ME7.3 as an idea;

1. Introduction:
Sufficient ignition energy must be made available in order that the sparking plug can ignite the mixture. This is realized by
closing the primary circuit of the ignition coil in good time so that the coil can charge up sufficiently.
On the other hand, the closing time shall not be too long as this can otherwise lead to the ignition output stage overheating
(particularly critical for internal output stages).
After closing, the primary current i increases exponentially with time. The period of time from the primary circuit closing to
opening again (sparking) is referred to as the dwell time.
The energy stored in the magnetic field is given by :
W = 1/2 * L * iˆ2 (L: inductance, i: current flowing at the point in time that the primary circuit opens)
2. Calculation of the dwell time:
The dwell time szout is calculated from a map that depends on the speed and battery voltage, corrected by a factor depending on the
engine temperature (from characteristic FSZTM).
3. Dependency of the dwell time:
ub: The primary current i flows through the primary winding of the ignition coil. This is determined by the battery voltage ub
and the resistance of the coil.
nmot: Above an engine-speed threshold, the dwell time is computed as a dwell angle and output at an angle level.
Thus a speed-dependent lead by the dynamics is required here so that a sufficiently long dwell time is still given even
in the event of maximum speed dynamics. The dynamics lead is taken into account in the map KFSZT.
The dynamics lead required is lower at higher engine speeds.
No dynamics lead is necessary in the lower engine-speed range (dwell time output).
It can also be meaningful to have a shorter dwell time at higher speeds for thermal reasons.
tmot: The ignition coil temperature changes with the engine temperature.

In kfszt.

Make rpm axis 7000, 7050(change depending on your limiters etc)

Put 0 dwell in 7050rpm row

Works in older me

It's all just relative - if Bosch have a known quantity, for example the bit at the beginning here that states 2ms, then you have a set known quantity, you can then work from that with various offsets and variables based on this known figure and elaborate on the variables to your hearts content and that's all Bosch do, continue to break it down and as such evolve the systems as a further breakdown of known/set figures. It's just maths and logic, that's all an ecu can do, I've highlighted some bits in the download file to give you an idea in red; the "offset", "function off", "gradient" type of bits;

I have had good luck with just using KFTSRL.  Never had to touch KFSZT but I suppose I will give it a try now after reading up on it.

I've been digging out and rebuilding some files lately and uploaded some ignition patent info if it helps on this, various years I think; makes it easier for me to find!
