Good Morning All

I wanted to report back on this. I've driven nearly 200 mi with no issues. I think its safe to say this is solved. The cloned ECU solved stall/ no start issue.

Finally!

In order to learn how to fix something, you must first learn how to break it.

Looking good. As an add on I ran a test with with a bad key over weekend.

Car started and ran with a good key in proximity to the bad chipped key, but when good key was moved 30cm at m the car stopped.

Conclusion....ECU immobilizer function is continuous during operation, not just startup, on mE7

This was the 1999
