Space Displacer question

I got the space displacer and was trying it out. I haven’t unlocked Inner Land Mines yet so I assumed the damage from the ILM produced by the SD would be based on land mine damage (especially since no damage for the ILM could be found on the UW section of the workshop) BUT the Land mine damage was 3.25q and the ILM damage was a whopping 642q. Where is the ILM damage and how do I boost it. If I get a sub module effect boosting ILM damage would that increase it, and how would I know?
