Here is the EFC Map that I built that works for many of my devices.


I found a device where my given map is inverted.
When my map is correct, EFC 00000 produces IR hex 9D (OBC 157).
When the inverted map is correct, EFC 00000 produces IR hex 62 (OBC 98).

You can convert MY EFC to its inverted value using the following formula:
AltEFC = (199 - MY EFC) mod 256

In Excel, AltEFC = MOD(199 - MY EFC, 256)
