Signs of a bad EDIS

Got a complete MJLJ with EDIS8 installed and all wired up.

Only problem is:
I run it in limp home mode without MJLJ. Starts up fine and runs rock steady idle 10 degrees for about 20 sec. Then the timing starts to jump around and sounds like it's missing, finally gets so unstable after a few minutes that the engine actually stalls. Same with the MJLJ connected. No difference if car cold or warm...

Sign a of a bad EDIS module? I have another one on order.

Car ran fine before with the traditional distributor.

Have you checked your trigger wheel and sensor is securely fixed? How does the RPM reading in the software compare to that on your car's gauge (if it's got one)?

I actually tried two different sensor and three ways to secure the sensor. Same results.
RPMs look same on MJLJ and the Tach. After approx. 20 s, the rpm start to jump around like the car is missing.
Would a bad coil do something like this?

What a pain that it was faulty but glad you got it sorted in the end
