Water pump control

Hi Guys,

Im looking into adding a CWA400 pump into my current setup. has anyone used this with EMU? looking for some help with setup please.

Thanks

just use a pwm output with dc function based on CLT and RPM

I`m using it on black with similar setup.

On PRO there is also LIN protocol, I think you could use the newer continental pumps.

FWIW I spent some time getting it working with an EMU PRO-8. Turns out the pull up resistor on the Aux output isn’t strong enough to overcome the pulldown resistor in the pump (at least the one I’m using - from a BMW N20 engine). The square wave signal was only reaching ~6V. When I manually added a stronger pullup resistor I got it to work.

If I were to do it again I’d wire it to a half bridge output.
