It cannot be the same bug because it isn't the same code. The MS2 vs. MS3 injection code is often very different.

But there is a bug. I've testet this with fullseq and with semiseq at two ports. All the same. Without changing the different deadtime, there are always differences at the squirttime.

James, it's the same thing, like Frank's post.
The PW curves in the log are a bit different. Like my msq, it was 1.25ms for Channel 1 and the basic 1.0ms for the channel 2.
So at the log ch 1 has everey time nearly 0.25ms more opening time. Only nearly, cause there are also different voltage corrections.
If you didn't have any ms2 in one our cars, you could test it at the stim.
Wrote the same daedtime and voltcor, the problem went awey...

Look at the actual values in your pictures... they are the same.
the lines look different only because your peak ms was higher for one probably only during Acceleration enrichment, that causes the scales to be different and not overlay each other perfectly.
I had the same look to a log once and then noticed it was the same values.
