Somehow noise levels raised after polyfuse (Vref goes throught it) and that was easy to notice just by lookin signals/voltages with oscilloscope. My solution was just replace that polyfuse wiht normal fuse. No more erratic noise after that mod and also AE works much more nicely now.

This has resulted in a significantly less noisy TPS signal, and to a degree, removed the need for any other type of TPS filtering.
The firmware in this post includes Rob's original tpsDOT moving anchor method and the new TPS averaging sampling.
You should be able to try either method, and/or both and see how you get on. I'm currently using both and feel it provides the best outcome.
