Lets give the new sensor a go, if it fails to resolve the hard misfire condition where I have poven the ECU is losing the engine speed signal it will be time to get the scope out.

The Canems system has crank sensor diagnostics of sorts, you can set output 1 to crank sensor diagnostics mode and attach an LED to it. Any flashing of the LED indicates a sensor fault, but I suspect the same wire could be scoped for a more complete analysis of whats actually going on.

Anyway apart from the very occasional hard misfire the engine has never idled better, and drivability is excellent so I am very close to the end game and have confidence the genuine Ford sensor is a logical purchase.

Dave I have set those crank sensors from 20/40 thou no issues they are fairly tolerant but like you say is the conditioner circuit scratchchin lots of variable's with after-market management , tooth logger within tuning software is OK but you cant beat a proper scoped analysis , this may be useful too https://shoptalkforums.com/viewtopic.php?f=66&...
