Coils dwell time error only on 2 coils

[Kamil]

Hello!

I have a problem, or maybe it just seems that way to me.

The engine is a BMW S54B32, everything works fine, generates power and I have no complaints.

However, on the log I see that I have a large dwell error on 2 cylinders and I don’t know where to look for the problem. It is on 1 and 4 cylinders, new spark plugs and coils, the engine is fully rebuilt and forged.

I thought I had the primary trigger edge set incorrectly, but after changing it I saw that it is fine as I have it.

Coils are BOSCH BMW 0 221 504 464, coil dwell time taken from EMU Black coils wizzard

Hi,
Dwell error is usually an indication of a trigger issue or incorrect configuration.

From the pictures, everything looks correct.
