Summary of change:
'''Subaru H6 engine factory trigger''' (engine position sensors) '''Do the Subaru H6 engines use HALL,HALL,HALL position sensors ?''' * from below ("capturing with both polarity") => indicates HALL,HALL,HALL * A guy from Latvia is ordering some (bare mainboard) for Subaru H6; Without good instructions (no wiki page unfortunately), but he seems to suggest 4*VR sensor inputs... is that reasonable for H6 ? (actually, he says "Subaru 6h", but that might be a typo) ** 4*VR would be good for SubaruEj (where the pictures and scopeshots clearly confirm VR sensor), but perhaps VR interfaces not needed for H6 (HALL is simpler, just some filtering and protection) ** any photo of the H6 wheel (or scopeshot) ? ---- InputTrigger/SubaruThirtySixMinusTwoMinusTwoMinusTwo (that has been supported for a long time) is very similar, but '''Subaru Engine H6 pattern''' is actually different '''(19, missing, 10, missing,missing)''' and this very arrangement only supported from firmware 1.2.12 Easy to start from a 4 cyl config and select "Triggersettings Subaru 36-2-2-2 (H6)" on the bottom of "primary trigger dialog" (VemsTune >= 2013-03-07), but if you have old "subaru 36-2-2-2 with camsync" config, the main setting to change is (IMPORTANT): "Ignore sectrig pulses above" = 94 * for geeks (who edit/verify .vemscfg file) secignore=5E (hexadecimal 5E, or 5F) From 1.2.12 most likely other patterns of the same concept are also supported with proper config (with or without camsync, but normally used with camsync - essential for VVTI anyway). ---- Patterns, configfiles, etc... '''[http://vems.hu/files/GintsK/Subaru%20H6%20trigger/benchtest/ H6 Benchtest related files]''' - including config, log while running, and triggerlog * was '''working fine with a wide window for sectrig position''': the bottom image as a starting point (fully retarded cam), and also with an extremely big cam-advance Engine works! However there quite often camshaft angle measurement jumps for huge angle like it would be measured in previous half-cycle. But it happens only at low rews <2500. * Maybe the pulse comes late so you need to use a '''different measure tooth''' value ? A higher value ? * It happens only at low rpms. Above measurement do not jump at any cam possition. IIRC minimal angle was 30 or 40deg - not too close. And wrong measurement seems comes from following revolution where cam signal occurs shifted 120degries (3 tooth per cycle). Here is my trigger settings http://www.vems.hu/files/GintsK/Subaru%20H6%20trigger/subaru%2036-2-2-2_H6_AVCS.txt. Copy it under C:\Program Files (x86)\VemsTune-xxxx\configlets\trigger and then trigger config is accessible from drop-down menu. Left camshaft sensor as primary. Tooth 0 in ref table belongs to 6th cyl. ---- * vvt subarus have '''two cam HALL ''' inputs ** newer engine with variable intake camshafts + VTEC-alike lobe switching use 3 evenly slots (240 crankdeg) on each camshaft. * the non-vvt only have one camshaft Two triggerlog files for old "dumb" H6 (== non-vvt ?, or captured with cams fully retarded ?). Files are captured with '''falling/rising secondary (HALL type) ''' http://www.vems.hu/files/GintsK/Subaru%20H6%20trigger/v3.3_n002316-2011-06-28-21.07.04.triggerlog http://www.vems.hu/files/GintsK/Subaru%20H6%20trigger/v3.3_n002316-2011-06-28-21.15.54.triggerlog Picture shows difference between both above files: http://www.vems.hu/files/GintsK/Subaru%20H6%20trigger/Merge.png Note: the sectrig pulse (should come every 2nd crankrot!) is watched in the ~100 crankdeg window before the "lonely tooth" (assuming "Ignore sectrig pulses above" = 94). Therefore the edge (especially sectrig edge, if sectrig is used) should be selected to match the BOTTOM picture (Gints, is that Rising or falling edge ?) * no sectrig pulse within the 10-pulse primtrig-group (when the cams are fully retarded) * when the sectrig cam is advanced (if it can be advanced at all), sectrig pulse might come within the 10-pulse primtrig-group (but between tooth 2..9, so not as early as tooth 0..2)
