I'm loving my 2006 Explorer except for the in town mileage, so I bought a Gas Saver chip from a company called RS4. I haven't installed it yet because I can't determine which two wires from the MAF sensor are for the IAT sensor. I've seen other posts that recommend that I send it back or throw it out. Why? Can it or will it damage my engine? If so, how? Or can it actually work? I understand that it tricks the computer into thinking that the engine is actually hotter/colder and then tells the injectors to work differently. Is that correct? Sorry, this is getting wordy. The RS4 website has testimonials and lots of info. They claim to have better chips than the 'older' types. Any help/advice?
Thanks!
Thanks!
