what does the card/device look like to the system?
meaning did you add a FakeID or DSDT/SSDT to make the device look like a 4360?
if i run "dspci" to list my PCI devices: i see this for my 1560
04:00.0 Network controller : Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) (subsys 106b:0019)
and you may want to put those FakePCIID kexts on the HD in /Library/Extensions
BrcmFirmwareRepo.kext: Install to /Library/Extensions. This kext is much more memory efficient than BrcmFirmwareData.kext and is the preferred configuration.
BrcmFirmwareData.kext: Most appropriate for EFI/Clover/kexts. BrcmFirmwareRepo.kext, while much more memory efficient, cannot be injected as can BrcmFirmwareData.kext
