I have this problem (pinging) on my '98 Jeep with a fuel injected 4.0L. 
Is there a way to clean piston tops for fuel injected engines?

You might want to consider some "old" technoloby and use water 
injection.  Fine spray of water (very fine) into carb while running 
will "steam clean" somewhat the top of the piston.
