Unfortunately for me it works the same as my old ECU.

So changed coil to plugs 2 and 3 , problem solved ,genuinely runs better than ever because it has had a slight stutter from low revs ever since I have owned it.
Did you measure that bad coil? I am curious if ohms are correct. I've got similar issue I think, I measured the coils (and they are fine), but I am curious if they can be broken even if resistance does not show it.

I did not replace mine yet, but I did not want to buy a spare since ohms are correct.
