Yep, that works, thanks.
I'm looking at the crank sensor voltage, and tried to use Window Dropout so it would trigger when the voltage stuck between 4.5 and 5.5 V for more than 10 seconds (indicating that the engine had stopped for that long), but nothing happens when that condition is met. So unless I can get that to work I'll just keep sticking my head out the door every 20 minutes or so to check on it.
Now I've got a more important question. I've got the crank, Cam W and Cam X sensors going into ports A, B and C. When the scope wakes up in Scope view it brings up the crank signal fine, but when I try to add views for B and C there's no option to select them: the scope doesn't appear to recognise that those ports are geting any voltage. When I run Cam W or Cam X to port A it shows good signals, so I know that's not the problem.
Then I tried Automotive/Advanced Tests/CamAndCrankSensors, but all it'll pull up is CamW.
I tried Cam, Crank, Injector and Ignition, and it pulls up all three sensors; it doesn't show the square waves very accurately and I really need the higher resolution, but you can at least see all of the crank teeth as well as the sync gap.. But when I save the data and open the file back up later the signal looks corrupted.
Here's what the crank signal should look like, you can see the sync gap clearly:
And here's what the crank and cam signals look like from CamCrankInjectorAndIgnition. The cam should show a short/short/long/long pattern over two crank revs (58 crank teeth per rev), but most of the crank teeth have been lost and you can't see a good cam tooth pattern. Crank is on top, the cams are on the bottom.
So what do I do? How can I view and record channels B and C? I prefer to use Scope view because I really need to resolve the short low time on the crank sensor.
