It does come with a few costs, as did the 912iS fuel injected engine compared to the 912ULS carbureted engine. This decision can be reversed. A benefit to fuel injected would be no carb heat control to fuss with, but on a 912ULS plane without a carb heat control, it's moot. (Both will remain available for now.) The 912iS requires a more robust installation, as mentioned, things like metal fuel lines which require exact fits, unlike rubber hose, butit also requires the sensor tiedownkit, which is a few hundred dollar kit,with sensor specific tie downs to eliminate false alarms due to sensor vibration. In terms of the CS prop, as I understand it, there is only one solution for US-LSAs being evaluated,and that is for a single lever control, and only the iS engines are able to interface with this system.

Once at altitude, Christian demonstrated use of the throttle and prop controls this was not a single lever control airplane to adjust for speed or economy. The single lever requirement is what caused the altitude compensated carbs to be implemented versus amixture control so it is likely the FAA will remain steadfast on this requirement. I wonder if this is the same defensive mechanism among maintenance personnel that used to be common back in the 70s and 80s when fuel injected cars were becoming the norm or do they know something about 912is we dont..? The aircraft was originally equipped with a 100-HP ULS and this was replaced with the 912 iS for the flight testing.
