Today’s electronic fuel injection cars are not like the carbureted cars of yesterday. Unlike a carbureted car, where a user can tune his or her air to fuel ratios by simply adjusting various parts of the carburetor, an electronic fuel injection system requires advanced programming to squeeze out extra performance from an engine. The makers of performance chips aim to change how you gain power with a fuel injection system. By providing your system with different types of tuning, performance chips are able to increase your horsepower, torque, throttle response, and much more.

There are hundreds of different performance chips from a large variety of manufacturers. Some performance chips are vehicle specific, and some performance chips are specific based on the make of car you have. Whichever type is needed for your exact vehicle, performance chips will work in relatively the same way. Performance chips are able to get more power from your engine by re tuning your factory air to fuel ratios. Whether you have modifications or not, there is always room for improvement over the tune that is included in your stock engine control unit or ECU. The ECU is the brain of your car that provides your engine with the timing and fuel controls that the motor requires to function. Your factory ECU has been flashed with the basic timing and fuel data it needs to meet certain model standards for fuel economy and horsepower. The stock ECU does not take into account a need for greater horsepower whenever you put your pedal to the metal.

Adding performance chips to your car will change your lack of higher horsepower by giving you timing, air, and fuel curves that are optimized for constant performance instead of overall horsepower and fuel economy. Sometimes, the advanced tuning performance chips provide, will allow for better fuel economy because your air, fuel, and spark timing are calibrated better for spirited driving. This means that you can actually save fuel while racing around. Performance chips achieve this in a number of different ways. Most of the manufacturers of performance chips have put countless amounts of time into researching and developing their products based on the specific needs of your vehicle. Cars get performance chips installed, then they are run on a dynamometer and the performance chips are tuned throughout every RPM increment to make the most your air, fuel, and timing.

There are many different performance chips available to suit different demands. Some may want extra power from their stock vehicles and others may have many modifications such as a turbo or supercharger, which requires air and fuel remapping to run correctly. When looking at performance chips, one should take into account exactly what you will be using your car for. Most basic or stage 1 performance chips allow for the use of low octane fuel on your stock vehicle. These performance chips have been tuned to optimize your air to fuel ratios for more aggressive driving, because your stock ECU has most likely been tuned for an average driver. Performance chips geared towards those who are looking to make serious power are designed for use with aftermarket parts and require the use of fuel with octane ratings higher than 91. Aftermarket upgrades can be as simple as an intake or exhaust to something as expansive as a complete turbocharged setup with larger fuel injectors. Most of the manufacturers of performance chips make their more powerful chips with a plug and play design for anyone simply running intake and exhaust. If you have heavier modifications, such as a turbocharged setup, performance chips will usually require additional hours of dynamometer tuning to ensure that your system is running exactly how it should be. Where performance chips install and how they function depends on the manufacturer. Some performance chips plug into your OBD 2 harness or on a port in your factory ECU and come with controllers that you can use to calibrate them yourself. Other performance chips install in your engine bay and utilize the signals of various sensors to provide your ECU with air to fuel adjustments.

No matter what type of modifications you have on your vehicle, there are performance chips that can handle the task of getting greater horsepower, torque, and even fuel economy out of your fuel injection system. Tuning your ECU can be as easy as plugging in performance chips. It is safe to say that in the industry of automotive enhancement, performance chips are here to stay.
