How about posting a current MSQ and MSL?

I would need to make a new log after it start behaving like this, I've lost control over the older log files.
I will try to feed it +12v directly too in case there is some problems with power to the ECU.

Problem "solved".
The MS 12v feed really drops below 5v sometimes during cranking on hot engine.
(I can not figure out why it does drop less when the engine is cold though, it's just very strange).
So I hard-wired it with an additional wire to the battery today and it started fine when hot too.
Good to have solved it, and I don't need to use the Hall-sensor I bought anyway.
