The MS/MX LR Refresh is one of the very few cars I haven't logged yet. Since that drivetrain is motor power limited (very rare) the SOC shouldn't matter too much. Although variable current required, like sport mode in the plaid.
Both 3D1 rear and 3D8 front are stated at 325V operating voltage with 840A inverters. Technically that is 273kW max, but I've seen the current go higher once before in the M3SR RWD NCA with 3D5. Calculated limit was 220kW, but it logged 239kW.
Rear 3D1 has Model 3 gearing and front 3D8 is a 3D1 with Plaid 5D1 gearing.
