We utilized vibration analysis to try and create trend data for pinpointing failing bearings in 2007-2008. It was worthless! After putting equipment in the hands of dealers seeing 50+ M96 powered cars per week we could not gather any information that was reliable. Dual mass flywheels are enough by themselves to create variances in harmonics.

It was difficult enough to use this type of equipment when testing aircraft (Helicopters) utilizing iterations per second measurement values. Half the time we were better off setting up blade trim the old fashioned way with trim tabs, targets on the blades and hanging ourselves out the crew door with a strobe light to measure the blade paths to set track and balance.
