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!
For the c129 signal, divby43, 1.1.98 (17-Jan-2012 or newer) firmware needed from [developer testserver]
- See the http://cell.dyndns.ws/f/README.txt how to install this
- (1.1.98 not released to the public yet, but actually seems better than anything before).
- With the 129 tooth, we tested beyond 10000 RPM (on the bench, including ignition and injection outputs).
- The change we did was basically a revert of change that was made to a certain request, but not extensively tested yet
- basically auditrigger behaviour should be now as good as back in 1.1.95 for non-3 divider also
- but with the desired changes - eg. allowing all 3 trigger signals to be connected and scoped independently with v3.
- 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"?
- also, should "two stroke" or "four stroke" be used in this setting?(latest config is set to two stroke)
- Why not use injgroups 0,1,2, and also set "Number of primary injectors" to "3" instead of "6"?
- 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).
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)
- [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
- it seemed good on the bench beyond 10k RPM, but we're retesting it extensively, also analyzing ignition events (count and position), also sweeping sectrig and special care around 3000-5000 RPM
- 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
- how was sectrig VR-polarity verified ?
- primtrig pulses == 129 for sure ?
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).
Per-cyl ignition delay is needed (because 43/3 != 14). Note: RPM reading might fluctuate, so divby43 is better choice
- 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).
