Newbie tuning saga of my LS Jeep TJ

[dave w]

At this point though I am wondering why I need a vss because I can't tell how I would benefit from the GM computer knowing the vehicle speed.
I am also not understanding why I need a manual transmission OS. This jeep seems to be fine with the original automatic OS with the torque management disabled.

It might not be necessary to use a VSS. When the tuning has challenges, adding a VSS is a good plan. There are several parameters that use VSS information, like DFCO.
