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. * A sloppy request sounds like: ** Subaru turbo, OEM engine, '''JDM 1997 2.0liter EJ20 280ps''' ** I think 1997 suggests 6+7 (and that suggests VR,VR can '''someone confirm VR,VR ?'''). EJ20R perhaps ? ** seems to match: EJ20R, EJ20X EJ20Y; two choices 6+7 VR/VR, or 36-2-2-2 VR + HALL/HALL ** See https://en.wikipedia.org/wiki/Subaru_EJ_engine#EJ20_Turbocharged ---- 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 ) ** we made a tooth-counting approach that Jorgen recommended that does not care about time between tooth for decision. It works since 2010-06-15 with experimental 1.1.76 and 1.1.78 (even with very quickly varying input RPM). Some [http://www.vems.hu/files/Firmware/config/trigger/Subaru6Plus7/vemscfg_test_2010.06.18-s060-s362_1.1.76_1.1.78good.zip configs] that were used for testing. * 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
