Right way to work on Octane maps?

[Denny]

Wondering what is the RIGHT way of working on Octane maps to get rid of knock? Please tell me if what I am doing is wrong..

1. Scan the car a good 20 minutes or so of normal and on boost.

2. Check the Histograms number#2 (total knock timing pulled away) I check for highest number of timing pulled.

3. Copy map

4. Paste it in my high octane map and substract from whats there.

5. Then flash new map to car.


Then Repeat number 1 -5 until I get no more KR.

Is there a better way then this? Is this totaly wrong?

Thanks.

Add one thing: Smooth around the KR areas so you don't have one cell mountains and valleys.
And make sure you are logging KR and not Total KR in the Histogram.

denny, did you find anything else out on this yet?

I've tried this with my car, and I started out with about 6deg of KR, got it down to about 2deg, then it shot back up to 6. Then I added timing back and it went back to about 3. So I'm confused lol....

Drop timing, or run a Wideband, either to rich or to lean, if your car is the cav in sig then just try dropping LTFT by 4 points, then do opposite if nothing or worse. Also this doesn't work if your car is commanding anything other then stoich 14.7 ie like PE or DFCO etc

Well I'm only tuning PE so...also I have a Innovate wideband and I'm running 11.5-11.8 afr's in PE. I could lean it out a bit and gain some more power but I wanna get this spark thing figured out....

If your fuel is fine then it's spark. Have you taken your spark plugs out? are they carboned up or gapped wrong. Wire brush them and regap just to eliminate one problem. It's always better to do the cheapest thing first.

Funny thing is my car started hesitating the other day, so I took out #4 spark plug and it had a tiny biut of carbon, well cleaning it off I dropped the spark plug. It was metal to metal and I didn't have a spark plug gapper (it's in a pile of boxes, just moved.) So I eyeballed the gap with channel locks. Runs great now haha. And yes I bought a new gapper and regapped it today. Good luck.

Yea actually I took my plugs out last weekend and cleaned them off.....I was having a small oil leak right around my cam towers and I guess it was leaking onto the plugs cause I was getting a misfire around 6500 but now its gone....I haven't been out with the car tuning for a couple weeks now....I need to get back to that lol....I'll post up if I figure anything out. Thanks for the help.
