Most diesel motors in cars and trucks are programmed by the factory at a set limit. This is just a basic run down of what these motors are capable of, if you want to get better performance and efficiency out of yours, you need to install a diesel chip in your vehicle. These are what any kind of performance enhancing device that is installed in your vehicle is referred to.

Basically what a Diesel chip does is reprogram your factory settings, to add fuel efficiency, and enhance performance. They are easy to use and operate, following simple instructions that are included with the unit.

They basically come in two different varieties, one is the electronic control module, that plugs directly into the wiring harness, replacing the factory module, and the other is a programmer, or tuner, which plugs into the OBDII port under your dashboard.

This port is a code scanner port that is used by mechanics to read diagnostics in a vehicle, such as determining why the engine light comes on at times when you think there is nothing wrong with your car.

If you buy the tuner diesel chip, it has instructions on the screen which guide you through the process of reprogramming your on board computer, changing the factory settings to performance enhancing ones. While this may sound complicated, it is fully automated and only take a few minutes to do.

These tuners are also the same kind of code reader that a mechanic has, so the next time your engine light comes on for no good reason, you can simply check and erase it, instead of having to take your vehicle into a shop. When you are done uploading the information, or checking the computer codes, you just unplug the unit and put it away. You can also use this device to return the vehicle back to its original programming.

The other kind, the module, plugs right into the wiring harness under your hood. The instructions that come this these tell you exactly where and which plug it is. Then it is simply a matter of unplugging the factory module, and replacing it with the diesel chip module instead. If you even want to return it to factory settings, you simple put the other module back in place.

What these diesel chips do is adjust the fuel flow rate, the transmission shifting points, and the timing curve, so that your vehicle will run at top performances. Increasing the fuel flow reduces the time the turbo charger needs to build pressure.

This also reduces the time needed to burn the fuel, actually increasing performance. Changing the transmission shift points, and the timing curve coincides with the fuel flow, and makes everything work together better to give your vehicle added performance.

Diesel chips have greatly evolved over the last few decades and are becoming increasingly popular, and the demand for these after market tuning enhancing parts has increased in demand. Companies like 4×4 And More sell many of these chips for just about any kind of vehicles, and are not just limited to diesel motors.
