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: Sec trigger enabled, now there is primary and sec trig in triggerlog, but No RPM or Spark.

You have no 6 virtual teeth between "cam" signal [in similarity as we have for audi where every second TDC signal is cancelled by Hall]. So try with 3.

may be 1.1.97 work with no divider? GintsK


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)


The engine actually ran for about 45 seconds (without sectrig enabled), it was just luck that it happened to fire correctly on that attempt.

Secondary Trigger:


We also tested with no divider (tooth width=2.75 deg): it worked, but peak-RPM would likely be limited.

We also tested with divby3, emil or pacsa will upload config and link here.

The good news that it works (so this is the recommended setup), but per-cyl ignition delay is needed (because 43/3 != 14)
