Emerald fan switch on / off

[hiltonig]

another question for those of you using the Emerald to switch the cooling fans what setpoints are you using ???

Was using on at 90, off at 85 but switched to on at 85 off at 80 on the advice of the guys at V8D. Seems happy and doesn't bring them on too often

As long as they switch just above thermostat temperature you could use anything you wanted within reason, but like V8D i prefer lower values rather than higher, and have the on temp only one or two degrees over the off temp so they cycle on/off frequently keeping air moving through the engine bay.

Mine was set to on at 94 off at 90, so ill change them, thanks chaps.

First fan set at 86, off at 78.

Second fan on at 88 off at 80.

I think both my fans come on with the same setpoint, I know when I asked Paul Dove to wire for fan control split fans wasnt mentioned. Bit of a shame as this is a nice to have.

This is what Paul phoned me about, in terms of how I had managed to do the wiring in the footwell without running additional wiring to the fans. I understood Paul was going to do this on your loom as well.

Easy enough to check, just go to the events page and put in differing values (even silly ones - low temp) for both fans and then run the car.

Stick one fan on at 50 and then the next fax to come on at 55 and you'll soon seen whether Paul did it.

nope he didnt bit of shame as I would have insisted on this one If i knew, Also I have also changed the fan setpoint but the Emerald is still using the old ones, whats the magic key press for the Emerald to store the new settings, also not getting on with the cold start challange, like getting the car to idle.

Some settings require to be uploaded to the ECU and for the ECU to then be reset (by turning the ign off then on again after a few seconds) to become embedded. Think the fan events is one of them.

Still don't follow why you'd ever want just one fan running... if it's hot, cool it; if it ain't hot, push the pedal some more
