Default B58 map2 log and Ign1 question - 09-12-2018, 12:41 AM

Hi!

I have some doubts regarding Ign1 timings.
I have a 340 without MPPSK, and I did couple of pulls with different IATs at map2.

if i run at IATs more then 100F Ign1 timings becomes quite low and i am worring about potential knocking activity in cyl1. I have also some other logs where Ign1 is much different from others.

If i run at IATs lower then 100F, Ign1 has no problem.

I have also attached this log files below.
So my question is, do i have something wrong with Cyl1? For example spark plug or coil. Or it is normal behaviour?

Thanks!

I also see Ign1 being more active than the others when on boost, anything over 4000rpm.

I see similar at times. Often there's at least two cylinders that seem to do this. I watch the trend of each cylinder and don't judge unless there's a big drop (3 degrees or more) on its trend.
