 # Knock Sensing
 
-TL,DR: We have native knock processing, with [Proteus](Proteus) and Hellen hardware support at the moment. We have very limited amount of testing on real vehicles: we know that knock is being detected, we know timing is being retarded, we do not have the body of best practices yet. See bits and pieces on the forum!

-## ASIC solution
-
-We have some progress integrating with conventional knock sensors but it's not ready for end users.
-We use TPIC/HIP9011 IC for knock sensor integration but no conclusive data.
+## Spectogram
 
-We believe that we have hip9011 hardware yet nobody has ever actually detected knock with a hip9011,
-someone would have to figure our calibration approach and test the overall implementation.
+Knock spectrogram is displayed by [TS-Plugin](TS-Plugin)
 
-Frankenso has hip9011 on-board

-Frequency is calculated based on bore, Freq = (900 / (PIF * (bore) / 2))

-We also have some results with ion sensing but it's not ready for end users
