Incorrect; look it up. I too am an engineer which is why I would never use an IAT resistor. Like I said, you do what you want. They are obviously selling these things and ill informed consumers buy them.

I hate to tell you but that is impossible. You cannot install a "chip" in the Edge's computer. The J3 port which a chip attaches to was done away with on all Ford computers starting in late 2004. A handheld tuner reprograms the processor through the OBDII port and is the ONLY way to do so on the Edge. Furthermore, no company has tuning support for the 2011 Edge yet including us. The 2011 is using a different processor from the 2010. I looked into it more. This is from their website: (http://www.gfchips.com/) "EASY INSTALLATION. Installation can be performed by anyone using simple hand tools. The GForce module installs into your FORD EDGE's engine bay and is connected via 2 wires that plug into the IAT sensor. Diagrams are included. The unit is then able to reprogram the ECU thus improving your car's performance. Everything needed for installation is included in this kit for a quick and easy installation that shouldn't take more than 15 minutes. There is absolutley nothing else needed to have this installed on your vehicle." So how is that not an IAT resistor?

I am in Florida too and drive a supercharged mustang (compressed air is hotter) and with a proper tune there are no issues with heat. Honestly I disagree with most of what you wrote. My suggestion would be to read more about what a tuner actually does and how it does it. Prior to OBDII standards when there were no flash devices there were bad things being done to "tune" vehicles. As things changed, people learned more and tuning became more of an art form. In a tune you are modifying parameters, not tricking them. You are adjusting transmission parameters to lower heat (which is what kills automatic transmissions) and you are doing many other things that increase the efficiency of the engine all while potentially increasing hp,tq and fuel economy in the process. Can a tune reduce longevity, yes absolutely...if done incorrectly. Can the IAT trickery reduce longevity, yes most definitely. Timing has to be retarded as a vehicle gets hot. The problem is, most manufacturers retard it too much. A tune will still allow this to happen but at a lesser degree. With tricking the IAT the engine is hotter than what the sensor tells the computer it actually is. So, the computer may think the temperature is 160 degrees but the actual temp may be closer to 200. Now, will you as a customer see this reduced longevity, probably not. Using a tuner allows the vehicle to still run completely within the factory parameters though at a modified level. Add in the ability to read and clear DTC's, and datalog sensor parameters and the device more than pays for itself. For your MAF, newer drive by wire vehicles are VERY sensitive in this area. Chances are no matter what you do, it will still set off the check engine light. This is why most cold air systems for newer vehicles require tuning. Ultimately you do what you want with your car and I am not here to sell anyone on SCT. I am not in the sales department, I am an engineer. If you want to use IAT trickery go right ahead.

Sorry, we do not yet support the 2011.

Being in the industry, I would never use one of those "chips." All it will do is trick the IAT into thinking it is actually cooler in temperature. The reason this "works" is the factory parameters are set to retard timing (minimally) as IAT increases so in theory if it is cooler less timing is taken out. You're tricking the computer and not measuring true temperature.

Hesitation like that is inherent in any drive by wire vehicle. Ford sets the system up this way for longevity and comfort. Through tuning though you can change the tables in the computer for better response.

Ford will not remove or raise the factory speed limiter. Aftermarket tuning companies like us here at SCT can do it though.
