I don't think it's the LA/Romeo that's the issue... your coils are mint. And the Romeo is always a good idea, even if the Ripper2 site suggests otherwise.
I find the detail that originals still worked the most confusing. That would suggest that the chip/install is the issue.
You said the consoles reacted like the LA was dead... can I ask what the symptoms were? Maybe we can narrow it down to something else.
