I've heard a rumour that the gen3 and gen4 pcm also controls fuel pump voltage , is this true and is it also possible to alter the voltage going to the pump using efi live?

i have looked into this a bit further and found out that the pcm does control the voltage to the pump but only on the VU and VY commodore utes.
