I have found the solution. The 1.6 changes names of interior of command pod.
For repair RPM go to : Kerbal Space Program > Gamedata > JSI > RPMPodPatches > PatchesStock
here you see 2 files for each pod.
Open the firs folder ("nameofcommandpod-patch")
The fist line is "@PART[*]:HAS[@INTERNAL[mk1pod_IVA],!MODULE[LifeBoat]]"
Change red by the name of new part interior. You can find this in "Kerbal Space Program > Gamedata > Squad > Parts > Nameofcommandpod > the file in .cfg.
Search the line : INTERNAL
{
name = nameofinterior
Repeat this for each pod who not works
Note : If you use custom asset for iva you must do this operation withthe file in .cfg in :
Kerbal Space Program\GameData\ASET\MK1-2_IVA_Replacement_by_ASET
Enjoy with RPM in KSP 1.6
