I believe both would work with the heated sensor, just the 510 will probably begin allowing the oxygen sensor to modify mixture sooner in the warm-up-- 15 seconds instead of the first few minutes. This function is programmed in the read only memory, and I have no details myself or dissasembly.

My guess based on this belief is the advantage of adding a heated sensor is more complete combustion during warm up and maybe extended idle, although your sensor location is still high up on the manifold junction, not down by the cat. So you'd be polluting less. Am I making any sense?
