So havent driven my car in a while..its been crzy hot down here in cali for the last few days..I noticed that i was getting knock at low boost.Could it be my iat sensor or just the weather affecting the tune.. Let me know please..

Or could it be false knock..Thanks

If your intake air is hot, then the charge air temperature is getting hotter too. If for whatever reason your tune is not checked the spark may be too advanced for this condition or the spark plug is hot enough to self ignite. If it is stock calibration it shouldnt knock as these conditions ie hot and altitude are verified during climatic testing.

 

Log knock voltage. Check spark plug gap and quality. Revise tune in knock area.

 

Hey guys, thanks for your input..got the problem fixed..This is gonna be funny, but my knock sensor was completely un plugged..Forgot to plug it back in when i I was connecting the main harness.

 

Haha, gotta love a simple solution but hate it when it's something so simple
