I know this is a REALLY old post, but I'm doing a mTDI build, and I think getting the timing via the 3rd injector and crank sensor is a smart idea with the PCB. I'm not a stranger to electronics and I was an UNIX Engineer / programmer for a few decades, so I think I can tackle this.
However, all the photos and information above is currently removed. If anyone has anything they could post up / send / verify etc that'd be awesome. Thanks!
