On the newer model B2B's, S/N 2015 and on, there is a whole new instrument package. Contact the factory for details, Maybe their engineer has put together an STC package for it to be installed on the older models. Good luck!!
I previously called the factory about an EGT guage and they recommended I get an Alcor, which is approved for installation on about any aircraft engine. I think I bought mine from Chief, but have not yet installed it.
