I hope to get his bad one in partial trade for another good spare from
me. I will open it up someday and see what I can see. I have another
dead 022 version here I got from a van at the junkyard so maybe I will
try the soldering trick on it one day as well. Wonder why the van was
junked?

The problem with carrying the butane soldering iron is who wants to open
what might be a good ECU and start applying heat to it far from home
with no spare? Once you KNOW it is bad why not. Until then.....

I think there is only 1 driver for all 4 injectors.
