I did a tpi setup and I took all the grounds from ms with a diyauto 8 ft wiring harness to one bolt and also terminated all my sensor grounds at that same bolt. My tps has about a 4 to 5 count variation wich is around 0 to -1 percent fluctuation in a data log. It looks worse in the ae tune window. 15% triggers it so its disabled. how much minimum is ok without needing to fix the fluctuation issue by trying to isolate the sensor grounds.
thanks
Josh

Re: Wiring question
It's better to take the sensor grounds into the DB37 connector rather than ground them to the main engine ground point. This prevents the high current flow in the main ground leads interfering with the sensor circuits. As shown in the MS manual external wiring diagram.
