Water Injection pump wiring

Recommended Posts

I'm not planning to use it just yet but am setting up a ban of relays for various outputs and want to know if I should provision one for my WI pump. I'm planning to use Aux3 for a pwm output but I don't know if i can drive the pump directly from the ecu (+122 to the pump and then earthe directly through Aux3) or if I should use a rela. I'm not even sure if a relay is suitable to use with a pwm output or if that will kill the relay? Does anyone know? Thanks, James

what type of water injection are you planing on using  as well as what pump   

if you are going to use the pump as a pwm then you will need a solid state relay

you will find you have better control if you turn the pump on and let it build pressure then use a solenoid to inject the water that is controlled of a 3d pwm map
