Does the OI gen 2 leaf board require the leaf PDM?

With my next conversion project, due to space/packaging arrangements I'll need to loose the PDM box that sits atop the leaf stack. I'll be using an Orion BMS and separate DCDC converter and charger. Will the OI gen 2 leaf board be able to function without the PDM?
I'm looking to use 2018 110kw stack.

Yup you'll be fine.

The OI board only effects the inverter and the pdm is not involved in anyway.
The 2018 110kw stack is a gen3 and the replacement board won’t work with it.
There is work being done (or was) on gen3 leaf inverter replacement boards, but they are not finished yet.
Right now canbus is the only method of control. Zombieverter will run it just fine

ah... I thought it was the 130kw that were gen3. So at present, is it true to say the OI board will only work with the 80kw inverters?
Will the Zombie run the 130kw inverter standalone? ie without the nissan PDM/charger/DCDC and rest of the leaf stuff?

Yes it can.

130kw leaf inverter I don’t think exists, there’s a 80,110, and 160.
Zombieverter will run all of them over can (no pdm needed)
And the oi board only fits the 80kw inverter

Oops, missed the 110kw bit. You might have gotten the 130 figure from reading about people getting about that much from the 80kw inverter + OI board?
