is there somewhere a solution to display the A340 Wheel, APU, Fuel, etc.
pages for the 2nd ECAM with PM ?
Still, it seems that PM doesn't offer this and HCSDT & Co only offer A320
systems which aren't 100% full compatible with PM (missing values etc.).

Why doesn't PM offer these ECAM pages themselves now that pmSystem seems to
emulate complex system logic ?
The Engine-Display is already there and it shouldn't be so hard to extend
this to support the lower ECAM, too.
