Experimental knock solution (actual for 1.1.51)

*Separate gain for each cylinder.



Set same settings as for original knock solution, knock_chan, retard, etc.

Set Gain for all cylinders "1"

Set min=90 and max=110, all references=100.

Set 797 to knock table if you want disable knock control at some area (i use it at low loads and rpm<1000)

See at log and fill table with treshold values, for example, log noise = 20-200, so set 300 at table.

Set mean value too, 250%-400% is good starting point.

Do not use selfcalibration, it is only for experiments and does not work as expected for a while.

There are 8channels for knock retard and 8channels for noise in log, instead individual power variables, you could use them for analyze.

My settings, as default:

knock_chan=21 means 00010101, it is chessmask for two sensors. use knock_chan=0 or 255, if you use one sensor at first or second channel.
