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)
The easier solution (for some) would be to bit-flip the OBC hex# (FF - IR#) before using my map.
Using the above numbers, FF - 9D = 62.
(All math is in hex.)
