David,
Mom and I won an Aerosonic fuel computer in a speed pilot-skilled air race in the 1970s and have been spoiled ever since.
We have found them to be highly accurate and at times good indicators of an electrical problem in the twin. Usually within a tenth on fuel flow after replacing the old transducers and plus or minus two tenths on fuel used - assuming the twin is level and is filled to exactly the same place.
Also a great indicator of which engine is failing or has failed - just in case you might have too much adrenaline flowing.
Almost forgot - tied to the GPS so determining surprise fuel stops if winds are worse than expected is a piece of cake. Good old Gallons Remaining at Destination is a favorite display setting. Keeps whoever is left seat honest.
Fabulous for managing tank changes. We can run a tank 'dry' but never have the engine skip a beat because the fuel flow variance is so noticeable before any hiccup.
