I'm new to this, and in the past few weeks I've gotten the VE tables close enough to move on. Now I'm working on the SA tables, and I'm lost. I have a 727 ecm, and I'm using TunerPro along with Data analyzer V11. Is there any way to group the knock counts into cells (0-15) similar to the BLM cells, so the SA could be adjusted by cell rather than rpm vs kpa? I've searched a lot of posts, and the FAQ's, and I'm just not getting it.

 

First thing is identify if due to A/F or fuel or mechanical.

WOT can be optimized by MPH 1/4 mile with no KC.

Keep in mind optimal results on a dyno like the mfg's do.

 

Thanks for the reply, A/F's were bad rich when I started (108-116) Now that I have them at an acceptable level (124-131) I'm getting 1-6 degrees of knock retard depending on where the rpm/kpa is at.

 

Pull timing globally and see if it goes away. If not it is mechanical

 

by that do you mean applying say a .85 correction to all cells in the main sa table?

 

yes

 

Thanks, I'll try it tonight.

 

The other option is race fuel added 50/50. I have a station near my home!
