First off, the wealth of knowledge of the members here is AAAWWWSSOME. I can't stop reading the posts and answers to issues. My hat is off to each of you.
Second, I hope to tap into some of this knowledge. I understand MAF tuning, VE tuning, idle tuning, but now I am working on spark tuning and am wondering about the methodology of tuning. Is there a custom PID that can be made, or any tricks to dialing in the advance quickly? I have worked on a few vehicles now and I am getting up to 10 degrees of knock retard on 1 of them when the MAF and VE tables are properly set.
Thank you for any and all help
