Appolo_sg, while you are right that grounding help to improve the electrical distribution, however, it also help to improve on the electrical flow and stability, if high quality electrical cabling are used. This also means less resistance at connectors of body, engine and transmission. Grounding also help increase low and middle engine torque, which will also mean you donÂ’t have to step hard on your accelerator, thus, indirectly saves you fuel.
actually improvement of impedance is really not great difference since the whole car body is a conductor itself, so by theory, resistance is also low. and no, it is an intermediary items, it is not an input or output, it does not help save fuel. you can use it to increase power by hooking fr -ve battery to base of ecu. but everything got to b done correctly. i think majority r done wrongly anyway.
