I'm sure I missed a thread on this somewhere, but would one of you mind explaining what a "power wire" is and what it does?

 

The power wire changes the value of the air temp sensor for the intake plenum and tricks the computer to think that the air temperature is cooler than it really is. Please not in my drawing I forgot to mention that the wire the resistor goes on is the (green/blue)

Isn't that bad if your truck starts overheating? Does this mean that if your truck starts heating up your computer won't recognize it in time and your engine can cease? or is that just too extreme...and what does tricking the truck into thinking its running cooler do to make you gain hp and tq?

 

Several sensors make up the information the computer references to change fuel mixture ratios etc. As far as temperature goes, the real info would be the water temperature. That is critical in that it must no get to a point of boiling out. The entire engine is kept in a jacket of water that is cool by the radiator and needs force are from the fan to do that. So the intake air should also be as cool as possible to keep the computer from having to adjust the fuel mixture for a hot engine. The intake chamber on many vehicles are now composite and that means they are inherently a cooler chamber for the fuel and air then with say aluminum intakes.

 

So been driving with the power wire for two days now and the truck run notably smoother with some extra kick that use to lost once the truck warmed up. I did without doubt lost a half a MPG. That driving it as I usually do. Still you beat the cost of that mod for the return in performance. Make you wonder what one could do with a righteous programmer or tuner chip kit. I'm installing a 180 degree stat tomorrow.

 

What octane are you running in it now?

 

General plus grade 87 to 91 Chevron/Sunoco/etc

 

If anyone is fabricating Power Wires I am interested in purchasing one.

 

Can someone reload pics of the power wire installed? The photos loaded in this thread are on the old site system.

 

Thanks eimer, I want to install one myself this weekend. and why 180 degree thermostat? Whats in it from the factory?
