RadRunner 1 (2021) controller specs?

[aaronbauman]

Hi, first time poster please be kind!

I'm brand new to e-bikes, and just got a RadRunner 1, 2021
Now of course i'm interesting in souping it up!
I'm looking for details about the stock controller.
Does anyone know where to find technical specs for the controller?

I see a bunch of discussion about controller upgrade, and I found technical info about the Bolton controller, but I'm interested in comparing to the stock parts I have now.

Thanks!
