keepin fans on below 70% throtle

[funcars]

I replaced my stock single rad. With a mishimoto slim 14". Now my temps are running higher, but staying under control. I want to either turn the fan on sooner and run longer or keep the fan on all the time under 70% throtle. I have the stock radiator and heat shield over turbo. Also thinkin of making under tray to keep air going thru front mount to radiator. Or make a fan shroud. Dont have money right now for a half sized triple pass mishimoto rad. Question whats the best route and what LS number are the fan controls nder. 91 talon tsi with 30-1300 series 1 EMS.

Turning the fan on sooner would be an easier route. Select Options,Scroll down to Configure Outputs,click Functions,scroll down to Rad Fan and enter the temp you want the fan on/off.

Here is a link for an excellent write up if you want to activate your radiator fan based of TPS: http://forum.aempower.com/forum/inde...c,25999.0.html

Thanks guys. I got it working how I want now. Now time to drive a little and see if that did the trick. I will still do a under tray to help keep air in the right direction. My car didnt have the stock one on when I got it.

Ok, I thought I had it but no dice. I have tried every low side and high side drivers and none seem to turn fans on. I went options the configure outputs. Selected rad fan and changed the on and off temp settings and that didnt do anything. I went to outputs and tried every one and nothing. Went thru the full list and couldnt turn them on with anything. Please tell me what I'm missing? I can hear the ems clicking when I select things but nothing happening (fan wise). But the fan is turning on and off normaly, I just cant change the min. on setting and anything happen. The fan is wired into the factory harness. Is there something else controling the fans? I looked on the aem forums looked at the pnp pinout and nothing is working. I'm sure its either something dumb I'm missing. I hit enter for every change I make and save the file to my laptop. It seems to be changing in the ems, i can close out and reopen and the changes I made are still there. They should come right on with the ignition on and my laptop hook-up with me changing on/off settings, right? Help!!! Going nuts I think.

Does anyone know which driver controls the fan? Or why mine does not turn the fan on when I switch it to on in the full list? I have tried all ls drivers.

A few questions:A) Did you change the on/off points in the functions screen or B) wire it according to the link posted? If A) Have you used a jumper wire off the battery to confirm the fan is working and have you checked the factory relay to confirm it is good? If B) You should post a screen shot with the applicable Output table cause we can't see how you set it up.

A)yes. B) I finally got the answer I was after on AEM forums. For some reason I was told with the PNP Ems we dont have control of the rad. fan. So I ran a wire off ls6 to the factory relay-ground side. Now I have control of the fan. So you actually only need some wire and one connector for the ems prong(plug), then splice the other end into the green/black wire under the relay box where the fan relay is. Why add a relay if there is one existing already. Of course this is if you are using factory harness. Thanks for the help.
