Summary of change:
'''Non-135 tooth''' related subpage of InputTrigger/AudiTrigger When installing an auditrigger setup with a certain number of teeth (eg. Porsche ?), elaborate on your project page created from MembersPage and we help configure (working/optimal) divider for the GIVEN (clearly specified!!!) number of cylinders and other related settings (and make bench-tests if necessary). '''Other 'Audi' triggers, part 2:''' 1.1.23 was only ment for 135 tooth. In 1.1.24, since when bit6=1 (primary_trigger=43) is used for auditrigger, auditrigger should work with tooth_wheel other than 5A (decimal 90, that is 135*2 /3 , using divby3). These numbers come from the number of teeth, and divider (divby2 or divby3). Examples: For '''264+1 trigger''': 4cyl 132 tooth and divby3, similar to the 5cyl 135 tooth, just different values (264/3 is 88 tooth and another_trigger_tooth is decimal 22): * primary_trigger=43 * tooth_wheel=58 * trigger_tooth=00 * another_trigger_tooth=16 * h[1]=00 42 2C 16 .. .. .. .. If there is no cam-hall masking (HALL is left high), than it becomes '''132+1''' trigger: * primary_trigger=43 * tooth_wheel=2C * trigger_tooth=00 * another_trigger_tooth=16 * h[1]=00 16 00 16 .. .. .. .. '''''Please see this MembersPage/PeteKrgr if I got my settings right with 1.1.24 / 132+1 / div_by_2 ?? Also if I change to div_by_3, is then bit7=0 ?? Thanks! ''''' '''volvo 142''' tooth no cam-HALL masking '''divby2 (bit7=1)''' * was supported in 1.0.36 (with different config) but in 1.0.36 RPM ceiling might be 7600 or lower (if teeth are uneven) * primary_trigger=C3 * tooth_wheel=47 * trigger_tooth=00 * another_trigger_tooth=24 ** OUCH: 142 after divby2 is 71, not dividable by 2 ! So Ignadv will be different +-1.2 degrees for cyl1,4 and cyl2,3 (still much better than cam-timing, but not optimal) * h[1]=00 24 00 24 .. .. .. .. Set the ign_tdcdelay to the angle from crankhome pulse to TDC. Than use strobelight * Porsche 944 has the 'crank home' tooth around 58.5 degrees before TDC * turbo's crank home is 66.8 deg BTDC = 24.5 teeth '''Porsche 130 tooth normally aspirated''' (turbo has 132+1 flywheel ) No cam-HALL masking, so 130+1 (not 260+1) Config hint (untested) <code> # rpmk=3000 (12000 / 4 cyl) rpmk[0]=0B rpmk[1]=B8 divider=01 # alternate=14 if you like batch firing during cranking alternate=04 # coil type, NO filtering, bit6=1 auditrigger=enabled # 1.1.23 requires bit6=1. And divby2 is bit7=1 primary_trigger=C3 secondary_trigger=19 # after divby2, 130/2=65 teeth: tooth_wheel=41 # trigger from every 33 teeth: another_trigger_tooth=21 crank_minper=00 # with divide-by-2, we see 130/2=65 per crankrot that is 5.61 degrees. So 365/(130/2) / 0.25=0x16 (decimal 22) tooth_wheel_twidth1=16 tooth_wheel_twidth2=00 cam_sync_r_edge_phase=00 cam_sync_f_edge_phase=00 reset_engphase_after=40 # PLEASE ADJUST _YOUR_ BASE TIMING! CHECK both ignition-pairs: 1,4 and 2,3 trigger_tooth=00 ign_tdcdelay=80 ign_out=70 ignchmax=03 h[1]=00 21 00 21 .. .. .. .. </code> Jaguar V12: '''162+1''' trigger (54 teeth after divby3) * primary_trigger=43 * tooth_wheel=36 * trigger_tooth=00 * another_trigger_tooth=1B * h[1]=00 1B 00 1B .. .. .. .. ---- How much tooth was old BMW Motronic? * 116 teeth on most BMW according to [page http://frwilk.com/944dme/math.htm this page] ** 116? Not dividable by 3: But primary_trigger=C3 is divby2.
