Summary of change:
: '''Subaru Trigger''' => See InputTrigger/ShortGapTrigger for config details 2001 and newer Impreza WRX have an InputTrigger/36minus2minus2minus2 crank trigger. 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''' * 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 are planning a tooth-counting approach that Jorgen recommended that does not care about previous times for decision * 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!!) * 36-2-2-2 setup (36 crank teeth, missing 2 teeth BTDC Cyl 1, and 2 teeth twice before BTDC Cyl 3, exact angle needs TBD). Seen on North American 2.2L SOHC plants (99-01 model using 2 teeth cam wheel) as well as other 2.0L/2.5L Turbo plants (most using 4-1 cam wheel) 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 (and possibly above what is practical with the chosen inputcapture - but not HW-counting capable - IC1 channel). I suggest to help out in the InputTrigger/AudiTrigger firmware, that board was designed for this. ---- '''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 ---- This is a subaru Impreza WRX+sti 2001- 36-2-2-2 http://img.photobucket.com/albums/v41/Denmark/Vems%20pnp%20Impreza/subaru2001-crankwheel.jpg http://img.photobucket.com/albums/v41/Denmark/Vems%20pnp%20Impreza/subaru2001-crankwheelpic.jpg http://img.photobucket.com/albums/v41/Denmark/Vems%20pnp%20Impreza/subaru2001-camwheel.jpg can someone make a trigger setup with this?,the newest firmware, maybe just crank, without cam sync, for wasted sparp. Could this be made to work, then this oe triggerwheel can be mounted on the older problematic 6/7 setups, and then just run cranksensor, but info to fill refthooth table needed :) Thanks, Skassa
