This auction is for a Zoom Performance chip/module. This auction will only fit the vehicle in the title for other vehicles look at my other auctions. All vehicles have an Electronic Control Unit (ECU)-a computer chip that electronically manages and monitors your car's performance-that is made according to government regulations. That means that your car could be going a lot faster and getting more power if you replace the ECU. That could cost up to 2000 dollars. This mod will modify your stock ECU with a Zoom performance chip. This mod connects to the car's ECU by replacing the Intake Airflow Temperature (IAT) Sensor. Once the module is installed, the ECU will read that the air coming in through the intake is cold air; think of it as a "default" setting on the ECU. When the ECU reads this, it leans out the air/fuel mixture-in other words, it will take in more air, and then add more fuel to compensate for the extra air coming in, thus, producing more power and advancing timing 1 to 2 degrees. Because the engine is creating more power, give your Car or Truck up to 20 More Horsepower!
