VR VSS signal - Noisy when stopped
My signal is excellent when driving down the road, but is extremely noisy while revving [stopped]. I can see up to 40mph when stopped and on the launch rev-limiter and a steady 2mph when idling. Currently I just have a twisted pair of wires, that runs within my entire engine "bundle" passing through the firewall. I am considering trying to fish some shielded cable through that bundle and rewiring it, but that is a last attempt.
Are there any settings here that I could look into to help that? I noticed that my TunerStudio manual image does not line up with my application, [see screenshot], perhaps VSS Sampling may help?
My log file is too large to upload and I am not sure how to shorten it.

Mine was noisy until I put a 10k ohm resistor across the wires.

Incorrect grounding can cause it, but I have had to use the 10k shunt as well.

I'll give that a shot, thanks!
