Question 2.8 knock w/ stage2 AEM intake ots map

So, i recently installed my down pipe and changed my map to OTS stage2 AEM intake 91oct map. i notice my knock would spike to 2.8 when i start driving my car from a stop at low rpm.. sometimes i get about .4 to .7 knock count when im in 3rd around mid range rpm. i couldnt tell you the exact rpm beacuse i use a Mac at home and i dont have excel or spreadsheet so i couldn't view the data log at home but i do live data log at times just to make sure things are okay. Has this happen to anyone? i'm not sure if it's safe to run in this condition so i switched back to stage1 AEM intake 91oct map.

here are my mod list: AEM intake box, GReddy IC pipings, AMS intercooler, AMS widemouth, Tomei exhaust..

note: i will get a pro-tune via email soon i'm just waiting for a few more thing to be shipped so i just wanted to try the stage2 map...

any advice or comments are greatly appreciated

Search. You will find that low-load/low-rpm knock is normal.

Also update your AP, you should be shown knock counts and not knock CA.

Clutch slip will produce a knock sum keep an eye on it once you go into boost. Our oem knock sensors are super sensitive and will register the clutch engagement/slip as knock.

How recent is this? I updated mine relatively recently and still see knock CA.
