Of course, I could be wrong (again).
My question is will you still need the Guardian if you have already fitted the upgraded IMS assembly considering that no failures of the ceramic bearing have been reported by either Flat 6 or LN Engineering??

It also probably has a sensor that senses cam timing. Variations in cam timing are also a sign the IMS is on its way out.
