Why do they write this on their manual on chapter 4 wiring:

Usually the biggest source of electrical noise isn’t RFI or other radio noise - it’s poor grounding or having noise injected into the power wires by another device. The MS3-Pro needs to be grounded to the engine block or cylinder head if at all possible; the battery negative terminal is often an acceptable second choice. We do not recommend grounding the MS3-Pro to the chassis or sheet metal
