thanks.
On my STI, I find 42% IDC (12 o'clock position) is a bit too late and choose to go for 10 o'clock which injects at around 25% to 30% IDC (I need to look at my HFS3 flow vs FIDC flow datalog). But I am using TMIC so injecting sooner is never a bad idea and I never saw any knock correction.

What is the value of you knock correction during the initial injection anyway? -1.4?
