I guess this is easy to test, I have 986, 996 C2 and 996 Turbo clusters on the bench and can just simulate the tank sender. That isn't a circuit that normally has any problems, so I have never needed to dig deep on those.

Nowhere near 100%. Trying to put together information from various sources and understand how the system works. I read straight from the sender into my race data logger, but the accuracy is so bad at the bottom end, if the cluster doesn't use the injector volume, i have no idea how it would get any kind of reasonable read out.
The DME 5.2.2 also has all of the necessary pinouts and data, and was only used on early boxsters and C2s, so I have no idea why they would implement it, and not use it.
