knock issues

If you have some logs you can look at the graph and prove it, but if not I'm not sure you can prove it from the last setup to this one. The only thing I really know to go by is if you logged some now and changed the afr and timing and proved they were consistent, even though they are high.

Peak is hard to look at also IMO just because it can spike in one spot and then be low through the rest of the rpm range. Mine stays around 10-15 at cruise, then spikes to around 55-60 right at seq. transition then holds around 30 the rest of the way up. I've done everything I can think of to make it not spike but it hasn't helped.
