I just recently looked back at my logs and noticed the ignition timing is pulling down to -6 under load at about 5,000 rpm on my Stage 1 BM3 OTS map and my Stage 2 BM3 E30 map. Is this normal or do my spark plugs need to be looked at? I also noticed slight engine knocks every once in a while...

Thanks in advance!

How many miles are on the plugs and coils? It doesn’t hurt to replace the plugs at least
Go OEM at standard Gap. The PTF Recommendation seems to create a bunch of issues

Finally had a moment to look through these, and honestly - I can't tell much from a log of you cruising.

You'll actually have to log a gear pull - 3rd or 4th 2500RPM to 6500RPM(or Redline)

Think of it like a dyno pull. They don’t hit record and then drive around. They hit record and go WOT seconds later. It consolidates the data to just what you’re trying to review.

Ideally you’ll get 2nd, 3rd, and 4th as you can see differences in timing etc in each gear. Just because 3rd looks good, doesn’t mean 4th gear is happy. Happy logging.

For a dyno, it's mostly based on load and gearing . For this I need at least one pull to review, I'm not asking anyone to get arrested.
