I think Cyl 2's intake valve is leaking on the power stroke spiking the intake with exhaust gas, right at the time Cyl 3 opens it's intake valve. See the overlay pic above. When Cyl 3 misfires it has spark, fuel and compression and all at the right time. That leaves a) measuring error or b) bad air....

Thanks, I like the plan for a one shot, think I'll use that next time I come to the it's mechanical conclusion. I focused on the faulty cylinder(s), eliminated bad new/old parts, eliminated ECU control, and then went in for in-cylinder, though I did do an RC first (all even). I actually now have an ...

This is a really interesting one, N53 Engine, misfires on 3+5 when cold, sometimes 1 as well. When it misfires all the ECU signals are there, spark primary on 2(good) vs 3 (bad) are normal and identical, current signature of (piezo) injectors is same on both. Cam/Crank timing is good. Borescope in t...

B/ What component in a cylinder can cause intermittent compression problems when the engine is cold some mornings and other mornings the engine starts and runs okay for days on end. Maybe take a look for coolant in the cylinder in the morning - that would fit your symptoms. - Inc shorting out the p...

Click on the channel, click "display" edit the channel name. Pretty sure I have a feature request in for just being able to click (or double/right click) on the channel name in the box to edit it directly which would make it easier, along with being able to turn the channels on/off from the channel ...

I always label the channels on the channel labels. Seems much more intuitive and does not take up screen space.

I get this randomly in T>200ms both in Linux version and Windows. Happens then goes away. Been appearing randomly for a while.

I would be looking at an insulation fault on the injector. Ideally you want an insulation tester but it might show up with an ohm meter.
The other thing to look at is a bad ECU ground - if both the cam sensor and the injectors are grounded through the ECU.

Yes it is an issue I just drag the original channel off the screen and leave the maths channel visible. Didn't realise that was different from Pico 6. It would certainly be useful.
