Diesel operation Chips - What Are They and How Do They Work?

Diesel doing Chips have been evolving for over a decade and counting. With the increasing popularity of "Tdi" (Turbocharged Direct Injection) diesel engines in passenger cars and trucks, the demand for aftermarket tuning products has also increased.

These products contain but are not little to electronic devices that I refer to as Diesel doing Chips. Clubs such as Bully Dog, Superchips, Edge, Diablosport and Hypertech and others originate devices such as change Ecm's (electronic operate module) circuit boards, modules that plug in to the vehicles wiring harness and also programmers and tuners.

The tuners or programmers are probably my favorite, second to modules. Tuners and programmers are pretty much the same thing, just distinct names depending on the manufacturer. I'll refer to them as tuners for the rest of the article.

The great thing about a tuner is that they plug directly into the Obdii port ordinarily settled under the dash. The Obdii port is a universal port that a code scanner can be associated to read Dtc's (diagnostic problem codes)

When a tuner is associated to the Obdii port, on screen instructions will guide you through the process of reprogramming the computer. Trust me, it's way easier than it sounds. The whole process is self-acting and only takes about two minutes from start to finish.

Most all of the newer tuners are also Dtc readers as well which will allow you to check and erase the codes if the check engine light ever comes on. A lot easier than having to take it to a mechanic to see why your light is on.

When a tuner's aftermarket programming is uploading to your vehicle or you are done checking the Dtc's, simply unplug the unit and store it away. A vehicle can be returned back to the factory programming at any time.

Modules will plug directly into the vehicles wiring harness. ordinarily all this entails is following the directions to find the strict plug most often settled under the hood. simply disconnect the plug, join together the module in the middle of where the factory plug was connected. Very simple.

If you want to return the vehicle back to stock, remove the module and reconnect the harness the way is way before installing the module. What most manufacturers refer to as an actual "chip" is a change circuit board that will need discharge of the Ecm and replacing the factory circuit board with an aftermarket unit. I tend to call all of the above Diesel doing Chips.

The way that Diesel doing Chips work in general is they reprogram the factory settings of the vehicle to settings that allow the engine to run more efficiently. Settings like fuel flow rate, timing curve and transmission shift points are the three I will explain.

Increasing the fuel flow can literally help the vehicle to run more efficiently, contrary to what one might think. When there is more fuel injected into the cylinder on acceleration, there is less "turbo lag." Turbo lag is the time before the turbocharger builds pressure. Lag is in the middle of when you hit the accelerator and when the turbo spools up and corrects the air/fuel ratio.

The longer the turbo lag, the longer the time it takes for the engine to burn the fuel more completely. By increasing the fuel, the lag time is decreased, thus development the engine more effective and giving it best throttle response. One more benefit to more fuel is that farranging while acceleration, more boost pressure will be reached giving a more unblemished burn of the fuel.

The timing curve is now reprogrammed to coincide with the increased fuel. At a higher Rpm, advancing the timing will give the engine more time to burn the fuel and again make the engine more efficient.

Changing the shifting points will also increase efficiency by keeping the gear longer under heavy acceleration and keeping the Rpm's lower under light acceleration.

I hope this article was informative and answers some of you questions about the differences in the middle of chips, modules, tuners and programmers.

The website contains data on alternative fuels and other ways to increase fuel mileage, but the main focus is Diesel doing Chips.
