thermo switching

Postby T-Bird24 » Sat Dec 01, 2018 1:34 pm

G'day
quick question? is there a way to switch the thermo fans on after the engine has been started. at the moment i am switching my thermo fans on and off with the PWM 1 and 2 setting, At my desired coolant temp. my problem is once i turn the ignition on with the engine at operating temp. my thermo fans switch on as well. the thermo fans draw too much battery voltage from the battery, so when cranking the engine its hard to start. because of the battery voltage been so low when cranking. ?? would the pull-up volts help with this problem ????

Not on an E11. You could use a second output and a relay controlled over RPM to control the switching of the main relay. Complicated, but it will solve it.

Is this feature added in Elite series? We wanted fans to operate only after engine has started running. So they don't draw currents during cranking. We have asked Haltetch for this.

Yes. There is a tick box to Disable when Engine Stopped.

would lifting my injector dead-time at lower battery voltage help with this problem.?
