Summary of change:
Porsche 911 Turbo '''6 cylinder engine''', engine unknown but had the Motronic from the 3.2 engine running before vems install. The engine is similar to MembersPage/MacB ---- '''Update: the car is running on 1.1.98 fw. Good job guys!''' ---- * '''injector outputs: only injgroup 0, 4 and 5''' were used (this might seem unconventional, it's all because the sectrig is not 720 deg but 360 deg), ** so we enabled '''2 inj outputs''' (we paired the outputs that are actually 360 deg opposite) in injgroups 0,4 and 5 (and '''left injgroup 1,2,3 empty'''). *** '''Why not use injgroups 0,1,2, and also set "Number of primary injectors" to "3" instead of "6"?''' ---- Trigger setup: Flywheel tooth and flywheel pin triggering, flywheel is 129+1. ---- ECU Info: ECU#4215 vr/vr trigger(auditrigger non camhall) Tlywheel Tooth Trigger to EC36-27 Flywheel Pin Trigger to EC18-12 ---- Here's link to 911 Workshop Manual, years 1984-1989: http://www.cannell.co.uk/911_72-89_Workshop_Manuals/84-89%20Workshop%20Manual.pdf Maybe there's some info on 911 Turbo as well.(MembersPage/PeepPaadam) ---- * '''[http://cell.dyndns.ws/f/v3_firmware_1.1.98.zip 1.1.98 (experimental)] was tested, and found good with this divby 43 config''' ** http://www.vems.hu/files/KevinBlack/porsche-1.1.98-divby43.zip with config, vemslog, triggerlog ** note: anything after "auditrigger with third trigger input software "camHALL scope" (2011-08-02) will NOT work, so '''1.1.96 and 1.1.97 will NOT work''' (at all with this trigger, see GenBoard/UnderDevelopment/FirmwareChanges ). 1.1.95 should work (we didn't tested it) * Trigger Edge: Rising * Trigger Type: Coil Type * Special Trigger Type: Auditrigger DivbyN * Audi trigger '''divider: 43''' * Number Of Teeth On Wheel: 3 (NOT 6, because only 3 per sectrig. 3*120=360 as sectrig pulse comes every 360 deg on this engine) * First Trigger Tooth: 0 * Next Trigger Tooth: 1 * Angular Width Of Tooth: 120 * Filtering and below: Disabled * reftooth: 0 2 1 0 2 1 x x (because teeth 3,4,5 does NOT exist) Secondary Trigger: * Mode: Cam Sync * Edge: Rising * Edge While Cranking: Single * Use: Cam Sync ---- We also tested with no divider (tooth width=2.75 deg): it worked, but peak-RPM would likely be limited. '''This special case of auditrigger worked on bench''', including the per-cyl delay, but '''only after tricking''' "divider-off, than "divider-on" (so we're working on initialization change, needed so it syncronizes without this trick, currently stuck in tooth_cnt=FF and wouldn't spark without this hack). Likely this will be the recommended setup). Per-cyl ignition delay is needed (because 43/3 != 14) * divby3 * toooth width=8.5 * Number Of Teeth On Wheel: 43 * First Trigger Tooth: 0 * Next Trigger Tooth: 14 * Angular Width Of Tooth: 8.5 * Filtering and below: Disabled * reftooth: 0 28 14 0 28 14 x x (because teeth 3,4,5 does NOT exist) * '''per-cyl ign delay: sg. like 0 5.5 2.75 0 5.5 2.75 0 0''' degrees ** needs verification with strobelight + adjustment if necessary * '''injector outputs: only injgroup 0, 4 and 5''' were used (this might seem unconventional, it's all because the sectrig is not 720 deg but 360 deg), ** so we enabled '''2 inj outputs''' (we paired the outputs that are actually 360 deg opposite) in injgroups 0,4 and 5 (and '''left injgroup 1,2,3 empty'''). ***'''see question at the top of page'''
