Thank you, Modtron.
To Mr_Matt, we were talking about the Jetcat ECU. We're not familiar with that product. Normally, you'd use a sensor supplied by the maker of the non-Futaba product. Apparently, though, what you need is no longer available. Likely, the software update was well in process when Robbe went out of business, and Futaba decided to complete the update because there are a number of Jetcat engine owners around the world who would want telemetry information.
