Hi guys,,

I have installed Diablosport predator on my brother's truck, he has gmc 2005 4.8L engine with manual 5speed transmission.

The problem is the cooling fan #1 dosn't stop working all the time even if turn the AC off. The temperatures shows in the programmer 189.1 F , i did a change to 205-215 F still working all the time!!.

anyone know about the stock temperature for fan #1 and Fan#2 maybe that will help.

One more thing do you guys know how to open the RPM to 6000RPM ?? still on 5600RPM i can't get more.

 

why dont you contact diablo about this problem they can help you out as well.they have a forum board

 

I have sent a message to Diablo's forum, waiting for answer

Thanks man anyway

 

How do you like the Diablo. Can you shut off the Torque Management with the Diablo?
Thanks,

 

The Diablo works great, good power and the truck pulls harder than before, except the cooling fan#1 always working.

Yea i can shut off the Torque Managmenet, but i didn't do it until now.


Thank you

 

You now have the fan set to turn on at 205-215? What is the turn off temp?

 

In the programmer it shows temp 189.1 F to turn on, but i didn't check in the turn off. I'll let you know soon.
