Yeah, the inside of the ECU may be all corroded up giving you erratic behavior as well. Since you didn't get much driving time when you first bought it, you may be dealing with a pre-existing condition instead of something you did wrong. i would look at that prior to tearing down the newly assembled motor.
Rule out any simple possible causes first.

no, its not, its just showing you the shape of the trigger wheel teeth. the trace will look like the one on the right side of the picture i posted earlier.
it sounds like it uses the zero crossing on the vertical part of the "backside" of the wave, rather than the "flat" spots. in any case, it doesnt use the peaks - ive never heard of a VR circuit that does
