RF Interference with EFI System

[Sparky]

IPU is Inductive Pick Up.
The easiest way to tell the difference between Hall Effect and IPU is, Hall Effect usually has 3 wires (Power, Signal and Ground), as IPU has 2 Wires ( Reference Hi, which is Signal and Reference Low which is a Ground)
A Hall Effect creates a Square Wave Pattern due to the on/off nature of the sensor and the IPU creates a Sine Wave.
