I found a device where my given map is inverted.

When my map is correct, EFC 00000 produces OBC hex 9D (dec = 157).

When the inverted map is correct, EFC 00000 produces OBC hex 62 (dec = 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)
