What? Why is an ECU controlled relay more reliable than a tachometric relay? They are both subject to poor connections and water damage.
Because the relays in MFi cars and alike firstly are very primitive and poorly made, but not only that they are all very under-rated. I dont think theres a MK3/4 on the planet that hasnt melted its relay, as soon as the pump gets a bit old and starts drawing a little more current they just burn out. They are rated 16A which is BORDER LINE for requirements.
The relay on an EFI car is rated at 30A, so there is A LOT less chance of failure/fire
