Visit Preferences to set your user name Summary of change: '''36-2-2 Suzuki trigger implemented 2022-01-16 in VEMS firmware (1 day after trigger specification completed).''' However, was originally specified wrong .... as tradition for 36-2-2-2 (was also specified wrong initially). See ((MembersPage/BogusSuzuki36-2-2)) Signalgen (z342), trigger detect firmware mod 1.2.44, release, configlet, testing done according to the specified wrong pulsetrain. * Luckily apparently new firmware is not needed ** [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_Camsync.txt trigger configlet] should still apply with minor config change '''secignore=01''' for the new pattern. The actual pattern: http://www.vems.hu/files/MembersPage/Suzuki36-2-2/real/trig04_camsync.png http://www.vems.hu/files/MembersPage/Suzuki36-2-2/swift_trigg03_scope.png http://www.vems.hu/files/MembersPage/Suzuki36-2-2/trig07_camsync_clet.png http://www.vems.hu/files/MembersPage/Suzuki36-2-2/trig_07_camsync_clet.wav http://www.vems.hu/files/MembersPage/Suzuki36-2-2/v3.3_u022060-A-2022.02.07-13.28.53_trigg_camsync.vemscfg http://www.vems.hu/files/MembersPage/Suzuki36-2-2/v3.3_u022060-2022-02-07-13.35.02.triggerlog Note that sectrig pattern is 24 tooth based, not 18 teeth... (total is 3 groups 240 crankdeg apart not 4 groups 180 crankdeg apart) http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki36-2-2_primtrig_and_1_1_2_sectrig.png [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/z342_600-12000_60_23_1000_1000_sectrig_1_1_2.zip wav with sectrig 1-1-2] Might '''need decode rework because of the originally bogus specified pattern'''... * Try secignore=01 (instead of 02; 00 is unlikely to work well). ** If no success with secignore=01 and sectrig enabled, please report RPM and vemslog with sectrig disabled also ---- [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_Camsync.txt 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 2022.02.07. Question: How can I set this trigger without camsync? The same configlet, just disable sectrig (no camsync; Burn and reboot). ---- '''DB - 02/08 - 11:27 - review of config: v3.3_u022060-A-2022.02.07-13.28.53_trigg_camsync.vemscfg''': * trigger configlet Suzuki_36-2-2_Camsync.txt is not correctly uploaded in this vemscfg * to avoid further confusion, i have retested Suzuki 36-2-2 trigger on bench using the '''real''' cam pattern, this works perfectly. * i have re-uploaded configlet [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_Camsync.txt Suzuki_36-2-2_Camsync.txt] and also added [http://www.vems.hu/files/MembersPage/Suzuki36-2-2/Suzuki_36-2-2_NoCamsync.txt Suzuki_36-2-2_NoCamsync.txt] for your convenience * download both files and copy them to your VT_INSTALL_DIR\configlets\trigger directory on your pc. * after restarting VT the Suzuki 36-2-2 configlets can be found on VT->Base Setup->Primary Trigger Settings-> defaults (bottom of dialog). * select the configlet of your choice, afterwards BURN and power cycle ecu. * after these steps you should have proper sync for this trigger type but still need to adjust tdc_delay and trigger tooth by strobing. If you run into any problems, please provide a triggerlog and vemslog (linke below this) of engine cranking 8-10 seconds without IGN and INJ fuse so i can review.
