Keep in mind, the gauges will only display what is outputted from the plane. Some of the planes use their own output variables - like the PMDG - so not all the gauges are cross compatible with each plane.
Which gauges are you using? I gave up entirely on the included Logitech gauges and have gauges from FIPgauges.com. Some of them are cross compatible and some are specific to PMDG. Overall, they are very nice and relatively cheap given the investment in the FIPs. The guys who makes the gauges is also super knowledgeable about SPAD and how all this stuff works.
