FYI I did have several clean pulls to 6k with this setup on the last engine. I’ve also taken at least one very solid 5500+(too rich) pull on this engine before the sensor went out. So I am focusing on sensor air gap and loose grounds at this point.
Sensor mount is very solid right between two bolts on a 1/8 steel bracket. However, it it IS inches from the alternator. Not optimal but again it was working fine until suddenly, and without any changes, it started having sync issues.

The alternator mounts through that gap between the two brackets.
