Summary of change:
'''36-2-2 Suzuki trigger implemented 2022-01-16 in VEMS firmware (1 day after trigger specification completed).''' [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_Camsync.txtonfig trigger configlet] needs strobing or scoping, adjust tdcdelay and all the usual install stuff. '''Syncs and continues to ignite''' * Without camsync * '''or with factory camwheel''' (tested with signalgenerator 1 1 2 2 pulses) http://www.vems.hu/files/MembersPage/Suzuki36-2-2/VEMS_Suzuki_M16_factory_36-2-2_trigger_2022-01-16.png Should be possible to configure also to non-factory 1 pulse camsync (if chosen edge pulse position is not very close to end of missing tooth). ---- '''Primary trigger pattern''' '''Suzuki m16 Euro5 engine from 2012''' trigger is '''36-2-2''' (=32 teeth total) : * 10 teeth and 2 missing * 22 teeth and 2 missing http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki36-2-2_Euro5.jpg Bottom pic is '''Euro4 Suzuki 36-2-2-2''' , a known existing variant (already fully supported, configlets available) MembersPage/SuzukiThirtySixMinusTwoMinusTwoMinusTwo which has * 13 teeth and 2 missing * 16 teeth and 2 missing, '''1 tooth''' and 2 missing That is 30 teeth total, 36-2-2-2 as we usually call. Mounts on the same crankshaft (orientation fixed by the drill at 3 degree) but it is a LOT of work to replace, (whole engine disassemble work) ---- '''TODO: exact details''' If the trigger pattern is known exactly by degree, including camsync, it can be implemented * Numerical degrees, positions * scopeshot, photo or trigger pattern, and/or reference * TODO: '''triggerlog''' * '''PLEASE PROVIDE cranking TRIGGERLOG with camsync enabled, falling edge ** (or rather separate triggerlogs, captured with falling and rising edges - burn and reboot between - files named descriptively)''' ---- '''Sectrig pattern, 4 groups (90deg = 180 crankdeg) is SAME as 36-2-2-2''' * pattern and relative position to primtrig is also important * 1 * 1 * 2 teeth (extra pulse appr 30 deg before?) * 2 teeth (extra pulse appr 30 deg before ?) ** the last edge of 2nd teeth seems to be "in sync" with the last edge of 1 pulse It is possible to grind off teeth from the camwheel. http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki36-2-2_primtrig_and_1_1_2_2_sectrig.png http://www.vems.hu/files/MembersPage/Suzuki36-2-2/SuzukiM16A_36-2-2_primtrig_and_1_1_2_2_sectrig.png NOTE: camwheel image contradicts "scopeshots" (and drawing) regarding the width of first tooth of the double campulse. Most likely the sectrig falling edges are inside the tooth-runs (either 1 or 2 falling edges, depending on cam position). http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_M16_36-2-2-2_camsync.png ---- '''(2022 or newer) Signalgen z342''' . please check wav in audacity and compare with your real scopeshots (provide your scopeshots or triggerlogs) * [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/z342_600-12000_60_12_1000_1000.zip signalgen generated z342 wav, camsignal with 12crankdeg offset] - '''believed''' to match real signals * [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/z342_600-12000_60_305_1000_1000.zip OLD WAV with 1 pulse camsync] - known to differ from real signal (perhaps close with grinded camwheel) http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_M16_signalgen_z342_primtrig_and_1_1_2_2_sectrig_camoffset12.png Check where the double campulse hugs the 36-2-2-2 single missing => it is fully inside the short (10 teeth) run of the 36-2-2 because of the different positions of the primtrig missing tooth. (Suzuki assumedly changed the crankwheel so that initial syncup at cranking can be a few teeth faster with sophisticated code.)
