These models are different depending on the type of the job you want to perform and the type of the car and ECU. Programmers have a wide variety of models. Depending on the type of the car or ECU, the Method of reading or writing the file can be different. Next week, however, we'll be changing gears and clarifying the alphabet soup surrounding passenger-car safety tech.Best ECU programming tool-These tools are a connection device between the laptop and the car’s ECU, which is used for reading and writing the ECU’s memory in different methods. We'll delve deeper into many of terms discussed in this article in subsequent posts. That's it for this week's installation of the ABCs of Car Tech, but there's plenty more tuner terminology to define and explain. In small doses, nitrous-oxide injection is mostly harmless, but larger "shots" of the gas will require that the fuel system and engine components be upgraded to keep the ratio of oxygen and gasoline within the acceptable range and to cope with the more powerful explosions. As I mentioned earlier, more oxygen flowing into the combustion chamber means that more fuel can be injected, which, in turn, means more power can be generated per combustion cycle. However, this oxygen-rich gas can be injected into the intake of a car to boost horsepower for a short burst. Nitrous oxide (or simply "nitrous" for short) is sometimes used as a low-strength anesthetic by dentists and doctors. Nitrous-oxide systems, such as this one by Zex, can provide a short boost of power when used responsibly. However, much in the same way that some people call all photocopiers Xeroxes, many uninformed or lazy tuners refer to all implementations of nitrous-oxide injection and even the gas itself as NOS. NOS technically stands for Nitrous Oxide Systems, which is a manufacturer of components used to enable nitrous-oxide gas injection for gasoline engines. Beware, however, of cheaply made carbon fiber components, which can be heavier (and in some cases, weaker) than the OEM part. When a car loses weight, it gains improvements to handling, acceleration, and braking. A well-made CF hood or trunk lid can save valuable pounds over an otherwise identical metal part. Although race applications and supercars use the material extensively for everything from chassis to suspension components, aftermarket applications are more often for body work. Seriously, when discussing cars, we're more specifically discussing carbon fiber-reinforced polymer (CFRP), a composite material that is both very lightweight and extremely rigid. CAIs usually sacrifice a bit of low-end torque for the top-end gains and can sometimes place the air filter in a position where it is more susceptible to water and dust.Ī magical material that simultaneously makes any car faster and more expensive. The result is often more power and a more noticeable (read, louder) engine note.Ī cold-air intake is an elongated intake pipe that positions the vehicle's air filter somewhere outside of the engine bay where cooler and denser air can be drawn into the engine's cylinders, which often results in more top-end power than a comparable SRI. An SRI replaces the restrictive air box and plastic tubing with a freer-flowing intake pipe (often made of metal) and a high-flow air filter. OEM intakes make horsepower sacrifices in the name of noise reduction, fuel economy, and, above all, keeping manufacturing costs down. The SRI is, for many car-loving kids, the first (and easiest) modification to a fuel-injected vehicle. Find the right car for you View Local Inventory
