What is the value of you knock correction during the initial injection anyway? -1.4?
base on my datalogs injecting at 25%-30% FIDC is around 300-400rpm earlier. what benefits are to be expected for injecting earlier?

yes, the knock correction is -1.4 during the initial injection. few days back i tried advancing more timing where knock is recorded during initial injection, and its at 0 knock now. perfect!
