Hi All
Im very new to the Speeduino forums and have a slight understanding of wiring but nothing on coding.
Im doing an engine swap and have been looking at using the BMW electric water pump for simplicity of the ancillaries belt on the engine.
The pump uses PWM for speed control, and my understanding is that the current firmware only allows for the cooling fan to be on/off operated. But I noticed the idle air valve uses PWM for control, which I’m not using, so in theory, could I use the idle air control pwm as the controller for the water pump or would I have to use an aux output to an external controller to power the pump?
I know this wouldn’t be useful for a lot of people as they’d probably use the idle air controller as intended.
For those interested, the engine swap is a Jaguar S Type 3.0 V6 with home brewed ITBs into a Triumph Dolomite. The ITBs are why I’m not running an idle control valve.
