Summary of change:
: '''Subaru Trigger''' is about the subaru 6+7 trigger (6 tooth crankwheel and 7 tooth camwheel) 2001 and newer Impreza WRX have a 36-2-2-2 InputTrigger/SubaruThirtySixMinusTwoMinusTwoMinusTwo crank trigger which is also implemented. Works with the (pictures at the bottom) 6 tooth crankwheel and 7 tooth camwheel. * '''supported with 1.0.x firmware and in 1.1.x starting with 1.1.72''' * some old info for 1.0.x are on InputTrigger/ShortGapTrigger * but '''with 1.1.x firmware the 1.0.x config will NOT work''', different config applies (needed: primary_trigger=A3, use the configlet from new VemsTune and verify according to GenBoard/UnderDevelopment/FirmwareChanges ) ** it tests good on bench, but DK guys suggest that cranking behaviour is bad. We suspect that sometimes 90degrees < 60 degrees because of the high rate of crank RPM changes during cranking ** with the (primary_trigger bit3=1) advanced filter=enabled and threshold=120%, 60% threshold (half of the configured value) can be configured for fiatstilo-subaru trigger (since around 2010-05-30 1.1.78 experimental) ** since 2010-06-08 (1.1.78 experimental) changed the default (advanced filter=OFF) subaru time threshold from 100% to 66%. (similar as if advanced filter=ON with 133% threshold). This makes it a more reasonable default ** we made a tooth-counting approach that Jorgen recommended that does not care about previous times for decision. Since 2010-06-15 with experimental 1.1.76 it works (even with very quickly varying input RPM) * see MembersPage/MichaelRichards/Projects/SubaruECU ** Seen on North American Legacy Turbo and the 2.5L SOHC plants (definitely on 99-01 plants, maybe on 02-03 plants and possibly earlier) ---- '''360 teeth not supported''' - the rest needs clarification. (separate page?) *Older Subarus(L-Series) with ECU controlled ignition have Crank-position [http://www.vems.hu/files/MembersPage/SRepo/Subaru%20trigger_plate.jpg Signal disc] in distributor. *360 little holes in outer ring presents Crank-angle in one degree/Percent precision (For engine speed signal) ** 360 pulses not supported. Rob made signal disks with less pulses, maybe they can be installed *Four long holes, are crank angle signal. One of the holes is longer, indicating (possibly) Cyl 1. (Working on it!!) Q: Any ideas how to make it work with genboar v3.0?? A: the 360-3 tooth crankwheel is definitely more than what current firmware can handle ---- '''Supported :''' Newer subarus (Legacy mark1) have triggers like these: [http://www.vems.hu/files/MembersPage/SRepo/Subaru%20Cam%20sensor.jpg Cam Sensor] [http://www.vems.hu/files/MembersPage/SRepo/Subaru%20Crank%20Sensor.jpg Crank Sensor] 7 tooth cam wheel: http://www.vems.hu/files/hackish/camwheel.jpg 6 tooth crank wheel: http://www.vems.hu/files/hackish/crankwheel.jpg
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
