Hello All,

Could you please support me in to calibrate the Knock sensor on 1.8t bam stock sensors, bot torqued at 20nm ?  
Engine have stock pistons with bore 81mm.  
By the formula provided F = 900 / (PI x R), = 7.04khz  
Now my question will be what Integrator / gain per each cyl i should use ?

Thank you !
