M227/8 & Seam are the same.
The main change is on the Solid & Infill calculation.
Into G-Code Prefix you have to put something like this :
; InterfaceSpeed [mm/s] = 25
; ShortSolid% = 40
; ShortInfill% = 20
; SmallLoopSpeed = 4
; LoopSegLength = 0.4
; LoopSegAngle = 22

Kisslicer use the same speed for Sparse infill and Interface, with Cubeitmod you can have a different speed for interface.
About Solid : the x/y speed is increased when the path length is short, when the speed reaches the Max Speed ( into Matl tab like cubeitmod5b5) the speed is maintained to Max speed and if the path becomes shorter the RPM are reduced. Le length of the path where this change append is displayed into the final message as PivotSolidLength. The RPM for shorter than PivotSolidLength paths are reduced linearly from the normal value used for longer paths to a value that is calucated with SolidShort%.
Infill works the same way, but with Infill% and InfillShort%.
Interface and Raft are calculated with the same parameters as Solid.
For short loops and perimeters it's the same as cubeitmod5b5.
