How do I log knock retard?

[zapp168]

I am running CO3 with a 2 bar MAP OLSD Tune I wanted to log knock retard but I can't seem to get it right. I figured use the same parameters as the spark table RPM vs Grams / cylinder GM Dyncylair. I set up the MAP for RPM VS CYLAIR (closest I could find that said grams / cylinder). When I log, it only logs in the first column. Call me silly, but isnt G/S from the MAF which I have now disconnected? And if so is there any other way?
THANKS....and BTW after 4 months I am starting to know enough to do some real damage.....LOL thanks to everyone who has helped me out....

You need to log both of RPM and DYNCYLAIR_DMA; and change the map to use those.

Not to be nitpicky, but for anybody else that reads this and might not know better... If you're running a 1 bar MAP sensor and are boosted, DYNCYLAIR_DMA will be incorrect. You'll want log DYNCYLAIR in the "Air" system or CYLAIR_DMA.

Sorry to threadjack but I can't find that in my PID list. I swear I was logging it about 1 week ago. How the PID is gone either or not I have all PIDs shown.

I figured it out over the weekend I did not have it selected in the PID list.
