Well, I think I have the answer. I drove the car around the neighborhood this afternoon for about 90 minutes. I was using Analyze Live to tune the VE table. In 90 minutes, I only logged a few sync losses. Not bad, I'm thinking.

This appears to be the answer:





I soldered a 1K resister between the power line and the signal line - a pull up resister. Everything I read in the manual and in the instructions says you don't need it. But a few people on the MS forum recommended it more than once. Out of desperation I tried it. It seems to have worked.

This week end I'll dial in the VE table a little more, but it doesn't need to be dead on yet. Then work on the accel settings. After that.... Wasted Spark!

I'm tellin ya, this has been one frustrating episode. I was about this [ ] close to giving up and going back to my Haltech. Thanx to the pro's on the MS forum, I think I can progress.

I'm not selling the Haltech yet, though.

As for the oil pump, I'm going to leave the distributor in place for now. Eventually I'll get around to cutting down an old distributor to make a pump drive.
