From what I have been reading the dominator will send out a pwm + or - signal, if I wire that to a solid state relay the relay is able to handle the pwm signal and will pulse the power or ground of the fan. Here is where I got the idea

So the way I understand it is the ecu is doing the controlling and can speed up or slow down the pwm and the relay will then pulse the power (or ground depending on hookup) to the fan.
To me thats what the stock e67 ecu is doing and sending it to this module which to me sounds like a ssr.
If I was able to get more info on this control module I may be able to understand it more but so far thats what I have gotten out of it
If this is just a nice ssr I was thinking of using it to control my fuel pump also because that is way less amps than fans.
Thanks for more info I hope I can understand this stuff even more before I have to start doing the actual work! |
I hooked my fans up to the holley hp ecu. I had to go in and turn the fans on and then designate two wires for 12-, I set the temp at when I want fan wire 1 to come on and it sends a 12- signal to the relay. I then set the temp for fan 2 wire and it also goes 12- when the temperature is reached. Seems to work good so far. For your fuel pump get a hold of Carl Casanova he is the owner of vaporworx. Good guy and great tech support.
