Repair of another Z owners Nistune installation gone frightfully wrong.
They guy who removed the Eprom obliterated every via and pad when removing the eprom. I had heard it's difficult job even with the right tools as these old boards are delicate. I loaned a spare ECU to the guy who owned the Z on the condition that he give me the other one to repair.
Curious about installing Nistune myself, i didn't know what i was getting into but have decades now of soldering experience.*
I ran new wire traces with solid 32awg wire strands, soldered them to and from traces that had been trimmed and bared and then potted them with a UV curable resin.

trimmed, soldered and cured.

control ecu i socketed myself with the professional rework tools i have access to at my employer (i didn't want to completely trash the other guys work without doing it for myself)

So i guess i can install Nistune boards now ? ‾\_(ツ)_/‾ Even milled out the pocket for the USB.
* I'm going to X-ray the rework on Monday to see if that decades of experience missed anything.
