Subaru H6 engine factory trigger (engine position sensors)
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...
[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.
Here is my trigger settings http://www.vems.hu/files/GintsK/Subaru%20H6%20trigger/subaru%2036-2-2-2_H6_AVCS.txt. Put it under C:\Program Files (x86)\VemsTune-xxxx\configlets\trigger and then trigger config is accessible from drop-down menu.
- vvt subarus have two cam 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)

Picture shows difference between both above files:
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)
