Autox cooling fans
 

Another forum talking about autox cooling made me think about a way to either install a lower temp fan switch or a manual switch. What are your ideas?

PS I searched and found 1200 different threads with nothing useful.

I set a switch up to ground the fan relay in addition to the ECU grounding it to give myself some flexibility. <shrug>

You could always just set it to come on lower in your megasquirt.

He doesn't have Megasquirt. Dunno if Link has that capability?

the Link can be configured to output a signal to a relay based on a temp it sees from the engine temp sensor. it is an adjustable value within the link.

I use to have mine set up that way many years ago when I had a link. FM probably still has some instructions kicking around there website for setting it up.

Wow, I didn't know the Link was capable of that. Eventually I see upgrading to MS, but I want to sort the suspension and prove the car is fast first.

Looks I need to study up on stand alones...

Don't over think it. Like stated above: Simple switch to ground to the current fan relays to force them on. If you forget to hit the button, you wont end up overheating on course. I've seen a couple of those. Usually Prepared cars, last one being an expensive CP motor :noes:

Link has some functions that tend to get overlooked. Like there is an output you can use to trigger the VICS soleniod (with a relay) or shift light. But it definitely is severely limited. Mainly when it comes to upgrading from the stock ignition.

the easiest way for a manual fan would be installing a switch to ground that connects to the TFA wire in the diagnositics box.

the really easy way is to do nothing at all and not worry about it.

FRom FM's tuning manual.

TEMP SWITCH XX: (Z9) On 1.8L cars this screen sets the temperature in *C at which the
primary engine cooling fan will energize. On 1.6L cars this screen is not in the menu, but Z9
sends a ground signal out on terminal 1L when the coolant temperature exceeds this setting.
Refer to the 1.6L ECU installation manual for details on using this feature.

Relay to the ignition switch. Can't forget to turn it on. Can't forget to turn it off.

uh...
