Summary of change:
Experimental knock solution (actual for 1.1.51)\\ \\ *Separate gain for each cylinder. *I tried intergator constant depended from rpm, data rise rapidly with rpm, so fixed constant works better, it is still here. *Noise window dropped and replaced with noise map 12x12 table share bins with Advance/BoostRef table. *Additional condition for knock check by mean value. mean_val=mean_val*15/16+knock_val/16; if (knock_val>mean_val*configurable_constant) then knock detected. *Separate noise reference values for each cyl, so threshold value = noise map value * reference value. *And selfcalibration for reference values and gain possible, average of knock values when 2000<rpm<2500 and map<30kpa. If too big or too small then change gain. *Retard delay dropped, retard applied for each knocking event without any delay.\\ *MT flashes RED light "Knock" instead "Misfire" \\ \\ 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. http://www.vems.hu/files/MembersPage/Andrey/KnockSettings/KnockCalibration.PNG http://www.vems.hu/files/MembersPage/Andrey/KnockSettings/KnockNoisetable.PNG http://www.vems.hu/files/MembersPage/Andrey/KnockSettings/KnockSampling.PNG
