Salaam,
I used to tune cars at Maxtorque
(2-3 years back)
If you are using a P08 ECU chances are it wont have a knock board...
Even if it has the knock board it wont be working because the natural frequency of knock of the engine expected by the knock board will be different for H22 then some SOHC D-series
Anyways for the H22 mild timing is recommended...
