Hi, what is the purpose of the sensor on the back of the engine that reads off the fly wheel and goes up to the diagnostic plug? I am stripping my engine of all unnessary parts at the moment as i now have EFI fitted. Just wondering if i really need the diagnostic plug now as i have a computer that i can read actual values off.
