But yes, i measured 12v dc on it. Mabye there is something wrong with the ms3 board?
Sleep is overrated. And I agree with the Prof, nothing is wrong with your board.
If your not going to get the Bentley, take the OE harness out and make your own. You have wired up something wrong, or something inside that OE harness is whacked up from your misadventures so far. A new harness from scratch, takes me at most 5-8hrs to make up. If you cut up the old OE one for materials, add a few more in. The amount of headache and time you have spent diagnosing this, you could (well I know I could anyways) have had it running on a new harness.
Did you configure the internals of your ECU? If not, then who did, and did they supply at least ECU pinouts?

As much as I agree (ESPECIALLY in this case), I have gotten along for many years with just a basic stim. Although I also suspect here that there is a good chance the ECU hasn't been configured or jumpered right internally... Having said that, a JimStim is very high on my list of tool needs/wants. But I have lots of MS related tools I really don't "need" and can easily get by without.
My own VW is running a very similar setup to yours. MS3+MS3X with a VR crank and a Hall camshaft. I have full sequential fuel. I did all my tests listed previously. She fired and ran on the first try. Well? Not exactly... Took me a while (and a melted turbo) to figure out that my "spark output" was actually configured as something else... Even KNOWING better from the many many installs I have done, I was sure something was wrong with the ECU.
VEMS has almost nothing to do with MegaSquirt. Okay so you ohmed the wires, but did you check to see WHAT else that VR + wire is connected to in the harness? Unplug the ECU and power up the harness. If your seeing 12v on that VR sensor, you are getting power on it from somewhere inside the harness, because you wired it up wrong.
Try this and eliminate the OE harness for the VR and Hall. Run new cables, even if just simple, temporary, twisted wire for the VR, and see what happens.
