Did you start getting the random misfire code after you upgrade the clutch/flywheel. As I understand it the sensor is so sensitive that the chatter of the tranny and lightweight flywheel, along with a higher than stock idle rpm, will set it off. I got that code when I first installed the kit. I had my tuner turn down the sensitivity on the sensor that trips that code and I've had no issues since. If I recall properly he just lowered the sensitivity under 1500 rpms.

Sounds like I'll disable it too if I can't find an actual cause. I'm going in for a retune in a couple months anyway so my tuner will have a few days to play with it and get it dialed correctly.
