I had an immobilised P73 sold to me
UKDM p73 are immobilised JDM ones aren't
I have the same issue
I wired in a voltage regulator to the eld pin and it dropped idle but now flashes the knock code with that connected for some reason I need to do a bit of messing about to get it right! I'll let you know as soon as I do!
And the P30 won't run the engine properly as its for a b16
Yeah it faults with no knock sensor connected will run like a burst ball too! Have you wired in the knock sensor? @BlueGhost
