# 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.

## 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.
|
|
|
|
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.

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
