In terms of pedal assist/max setting on the Levo to be similar to a 85nm Bosch Gen 4 modes I would guess something like
LEVO Gen 4
Eco 20%/35% ( Gen 4 ECO)
Trail 30%/85% ( Gen 4 Tour)
Turbo 90%/100% ( Gen 4 Turbo)
Gen 4 has EMTB mode however. I have both a Levo and a Gen 4 bike and I spend most of the time on the trails in trail on the Levo and EMTB on the other bike so those are the 2 modes I would want to be roughly similar. The problem is however that EMTB provides a relatively smooth progression of motor power up to its maximum whereas trhe Levo Trail mode enables the pedal assist motor power selected to be easilly accessed but progression from there to whatever is set as maximum get pretty hard to access.
To make Trail more like Gen 4 EMTB I would set Levo Trail as 40%/85%.
Note also Gen4 needs a higher cadence than the Levo to get roughly the same motor output.
