Nice. Will you be going into more detail on the internals of the ECM? I have one I need to fix, I should probably pull it apart and look at the solder joints first.

Lastly these are conformal coated aren't they, what is the best way to remove the coating to get to the pins?

I normally use Acetone on a Q-Tip to remove the Conformal from the pins.
