About Diesel Performance Chip - What Do You Know?

With the development of science and technology, people's work in various fields is more detailed. Do you know that all the ordinary 4X4 diesel on the market use some common rail injection system?Compared with previous mechanical pumps, it has better economy, more power and control of fuel delivery, which undeniably comes at the cost of increasing fuel. Next, The VIP Pro Shop Team will tell us more details.

While older mechanical diesel pumps deliver fuel directly to the cylinders, modern pumps circulate through accumulators or directly to the injectors' rails. The computer can then tell the injector when to open, how long to turn on (called the duration), and how many times each combustion cycle is open. It is far more precise than simply injecting fuel into the cylinder and expecting the best results.

However, car manufacturers (for various reasons, including local fuel quality, different emission regulations, etc.) tend to adjust their engines very conservatively. This is where the performance chip or module comes in. Most standard common rail engines usually have more power and ever-increasing fuel efficiency, and installation is often as easy as plug-and-play. But are they really good for your engine

Rail pressure type

Some modules plug into the common rail pressure sensor circuit and manipulate the amount of allowable fuel pressure to be stored therein, effectively causing the ECU to recalculate fuel amount and time to account for increased pressure. In short, as each fuel injector opens, the greater the pressure in the rail, the more fuel is injected into the cylinder, thus generating more power. It sounds simple, but a bit more complicated than simply solving the stress. You also have to make sure that the units you buy monitor the throttle position, not just the pressure on the wind pressure rail up to 11. If you made 30 special roads, I hope you do not engine rebuild ...

Syringe duration type

These are plugged directly into the injector harness, essentially keeping the injector open longer (remember, we're talking about microseconds here), allowing more fuel to get into the combustion chamber. Their installation is slightly more complicated than railroad pressure, requiring access to the factory wiring harness - but if you're comfortable with a soldering iron, they can still be installed by a competent domestic mechanic. With that in mind, a seminar will be able to do this at a reasonable price (usually more tidy than most).

As with all performance modules, while increasing injector duration is a major feature of this type, the mass unit will perform a great deal behind the scenes - for example by recalculating several key algorithms in the ECU so that over the entire speed range Increasing power safely inside does not affect reliability - it's the key to installing any power-on modification, i think

Combination type

These modules are slightly more complicated than the first two modules. They work at orbital pressure and injector duration as well as other operations controlled by the ECU, such as turbocharged pressure. They are almost like a fully replaceable auto ECU chip and provide a more complete mapping, albeit at an added cost of installation complexity - that must be connected to the wiring harness at a few points. And they are more expensive, which reminds me of the next point.

Before reading this, re-examine your engine!

Then, so you've decided how much more you need to do from your engine. Hey, cheaper things will not be a bad thing, right? So you entered the "Diesel Performance Chip" on Google and popped up a variety of different types, claiming to be the best, without any reliability issues and some are simply the cost of steak dinner, so what could have happened? In fact, there will be a big problem, then in fact, you understand that not all of the performance modules are the same. Some are actually useless, even he will be misleading. As you can imagine, this is not good for your engine ... even a suicide.

The rest is just a black plastic box with a plug at each end that can be inserted into the harness and then completely inaccurate. Unfortunately, we live in a world of low prices and poor product performance. So pay attention.

So which store should you go to?

This is one of the small surveys. In fact, it is a long way to come into contact with the manufacturers and ask some questions. Try not to pay too much attention to how much extra power you will get, but ask how to provide that power throughout the speed range. If you have ever driven a dynamometer then you will know that the large increase in torque curve is always better than the spikes between 3,000-3,300 rpm.

The quality module will monitor a large number of engine parameters at runtime, so there will be no negative impact. Yes, good usually costs more money. But it is cheaper than replacing the pump or each injector. Choosing a device that can be readily adapted to driving conditions and throttle input should be mandatory, providing chip makers a whole bunch of useless stuff right there if they are not familiar with how their products work. After-sales service and warranty are two other key factors to consider.
