I added these definitions to the end of the .sfg sensor file. They were working. After a file tweak they are not being displayed in the available
list during input sensor mapping
What am I missing?

Try it now, made a few changes. It works for me. Some of your names weren't valid and had illegal characters.

The file is now accepted by Skyview. My Autometer Oil Temperature, Oil Pressure, and Fuel Pressure senders are working fine.
Thank you and RaymondJ for his super informative post with regard to the Westach Sender and how he went about determining the new coefficients. I had to come up to speed on what a Stein-hart equation was and reintroduce myself to the Gnuplot program. It was interesting, entertaining and it works.
