Since this subject comes up now and again and is the source of hijacked threads I've created one just to discuss this alleged useful item. The product MINI COOPER G-Force Peformance Chip My contention is this is a product designed for one thing only, to part a fool and his money. Now I've never seen, purchased or used the product in any way. My opinion is based solely on the years of experience I have in modding cars, reading and writing ad copy and just the general issues I find with their site. To whit... They advertise a chip is available for many vehicles that have never even seen an ECU. To me this means they used a generic vehicle database listing and didn't even bother to take the time remove the entries that not valid. If they do not attend to this simple detail do you think they really take the time to create a "tune" that is best for your car? Where do you find an AIT Sensor on a 1973 Triumph Spitfire? Or a 68 BMW 2002? we can back further too. How about a 56 Hudson Hornet 4DR Sedan? That 1950's era Porsche 356, yeah, that has a need for this item. Every one of these examples are on their site. The other problem I have is how this works. From the site: Two wires that plug into the AIT (Air Intake Temperature) sensor. From my years of experience to me this means they are adding a resistor of some type in line to fool the ECU into thinking the intake air is colder than actual. Is this really how you want gain more power, by tricking the ECU?

From what I can tell doing some searches you get this "chip" with two wires coming off the box, 2 quick connectors and 2 zip ties. Something along the lines of the items displayed on the left. Someone on the zcar forums purchased one from SLR motorsports, another company that advertises the same thing and has a very similar look and feel to the site as G-Force has. Look at what they got. Yeah, 15 cents worth of parts at best. Other items that toss a red flag to me: The domain is hidden when ownership is checked. Makes it harder to go after them. Do companies that have little to hide when it comes to contact info do the same thing, very rarely. Do a search for reviews. Educate yourself, but I still contend that the $69 spent on this would be about as useful as buying hurricane insurance for your house in Manitoba.
