Please understand that the example codes shown are purely examples. There are many other codes that your computer could be. If your code is not shown, we can still make a chip for your car. There is no chip code we cannot do (that we know of). This chip isn't replacing a chip in your computer, it's piggy-backed to the existing computer you have. It interrupts the factory settings and supplies our own.

Locating Your Computer Code

Locate your computer. If you have trouble locating your computer, please contact us. On the bolt-in harness connector of your computer is a white sticker measuring about 1" x 4" with a UPC bar code on it. On the sticker above the bar code should be a set of BIG BOLD letter and numbers. Those are the numbers we need. The alphanumeric code should be on its own, usually ranging from 3-4 digits. See the above examples. If you are unsure what numbers we need, write them all down. In the rare event that the code is so new that we don't have the internal computer code, we need your computer sent to us.

How NOT to Find Your Code

  • DO NOT take the numbers printed onto the other side of the box. The numbers we need are on a white sticker on the computer as indicated above.

  • DO NOT look on the door jamb -- it's in the hinge area. The emissions calibration code or any other set of numbers found there will not aid us.

  • DO NOT copy down the VIN number. We need the number off of the computer.

  • DO NOT call your Ford Dealer for the numbers -- they will laugh at you. Ten identical vehicles of the same make, model, and year can easily have different computer codes. Your Ford dealer cannot guarantee the correct code for your vehicle.

Once you have those numbers, we can program your chip!

When calling or emailing an order, we need to know the computer code, make, model, and year of your car, the engine size, and any aftermarket parts you may have added already -- remember our performance chips are computer code specific -- that's why they're the best!!
