Hello Everyone.
There seems to be a lot of confusion about rail pressure chips vs injector control modules such as ours (I'm sure everyone has seen the debate in some other threads). I'm going to explain the difference between the injectors, how increasing rail pressure effects them and how a module that controls the injectors differ.
First and foremost there are 2 different types of injectors used on commonrail diesels. The First and most common (found in navaras, patrols, hilux, prado, etc) is the Electro Magnetic Solenoid style injector and the second is the newer Piezo-electric injector which is not readily used hear in Australia as of yet but in saying that you will see it in some of the European passenger cars and has come out in the new Ford Ranger/BT50 3.2 and 2.2 engines.
The difference between the two injectors is one is controlled by an Electro Magnetic Solenoid and the other is controlled by an actuator module made of quartz crystal when current is applied to the crystals it causes them to swell. The quartz crystal is like a little ball of round foam as the current is applied to it, it swells, one of these quartz balls is far to small to see with the naked eye and when current is applied to it the expansion is way to small to be seen with the naked eye. Each injector contains millions of these crystal balls which control the injector. There for when these crystals swell they push on the solenoid to open the injector. Fundamentally the injector has not changed, the fuel still has to overcome the tension of the spring keeping the injector pin shut. They are using the quartz crystal in the new injectors because opens and shuts a lot faster then commonly used Electronic Solenoid Commonrail Injector that is used here in Australia today. It can also open and shut more times per revolution then what a Electronic Solenoid Diesel Injector will.
Because the Piezo Injectors are not mechanically operated small increases of rail pressure or stabilizing of rail pressures would not be as detrimental to this style of injector as it would be to an electronic solenoid injector. That being said, increasing rail pressure without addressing the injection timing of the injection of the diesel will cause unwanted diesel rattle due to the fact that too much diesel is being injected at one time and when the voltage from the fuel rail sensor is being reduced (by the addition of a chip) the ecu is being tricked into thinking that there is less fuel pressure there then what there really is and also advances injection timing on most vehicles. So now you have a) too much fuel and b) incorrect injection timing which is detrimental to the injector as it hammers the end of the pin of the injector and significantly shortens the life of the injector. Also lifting rail pressures over and above the recommended pressure causes a much larger pressure head on the pin and while this may cause the piezo injector pin to open more, this is not the case the commonly used electronic solenoid injector which requires instruction from the actual injector itself to open the pin further.
At the end of the day a product being fitted to a car needs to be engineered to work within the engineering of the components that it is manipulating. When it is possible to control the injector electronically this would be without a doubt the best possible way to insure durability of the injector and the life of the engine. Just controlling injector voltage in milliamps and Millivolts is not enough, which is what most of the modules on the market are doing right now. Diesel Smart Modules control not just milliamps and millivolts, but also a wide variety of parameters that are available to control the injector as it was engineered to do so, we're not going to release publicly exactly how we control the injector as it is quiet obvious to us that we are the only ones that are controlling all of the parameters. The saying goes the proof of the pudding is in the tasting, ours tastes good
Power, Torque and fuel economy will always be much better then a chip that is only forcing more fuel in. If you are a customer then you would want to make sure that the product you are purchasing is working within the specifications and engineering of your engine and its components or leave it standard, that is our advice.
