Managing a truck takes a lot of work, and you can use many tools to keep it in shape and even improve it. One of these tools is a diesel tuner, and when you use it, you can improve some internal configurations that the manufacturer placed on different parts of your truck. These diesel tuners can tell you a lot about your truck, and when you use one, you can change those configurations, giving your truck the performance boost you’ve always wanted.
The speed limiter in many modern cars prevents vehicles from traveling over a set speed. An intelligent speed assistance (ISA) system typically stops your vehicle from exceeding the pre-determined top speed the manufacturer determined would be dangerous. A diesel tuner can tell you what this speed limit is, and you can then adjust it and remove it, lower it, or increase it, depending on your preference.
In your truck's engine, there’s something called fuel rail pressure that the electronic control unit (ECU) monitors. The ECU can change the rail pressure depending on the engine's needs, so fuel pumps to the injectors as optimally as possible. It regulates the fuel pressure in the fuel rail, but with a diesel tuner, you can monitor and adjust this pressure. When you tune your rail pressure, you can boost your engine speed by milliseconds. Milliseconds may not seem big, but they can make a significant difference.
Injection timing refers to when your engine injects fuel into the combustion chamber. This injection normally happens as the crank angle degree (CAD) changes relative to the engine’s piston’s top dead center (TDC). However, you can see and modify the injection timing with a diesel tuner, positively impacting your engine’s overall performance. You can slow or speed up the engine timing to solve issues in your engine, boost fuel economy, or fix engine temperature issues.
Rev limiters are an essential part of a truck because they’ll protect your engine from pushing it past its limit, but there is some wiggle room you can work around. With a diesel tuner, you can alter that window for maximum rotational speed. However, like with all of these modifications, you should be careful not to push your truck’s engine too far.
The coolant is an integral part of the system under your truck’s hood since it keeps your engine within a safe temperature range. However, within that window, some temperatures are better than others. A diesel tuner can show you your average engine temperatures, and you can adjust these temperatures, so you have a warmer engine start that boosts drivability and fuel efficiency.
A diesel tuner can tell you a lot about your truck, and when you know more about the different internal components, you can give your truck the improvements you’ve always wanted. However, you must remember that not every tuner is the same. There are different tuners for different truck makes and models, and finding the right one for your vehicle is essential. If you have a Ford with a Powerstroke engine, come to us at Norcal Diesel Performance, we have the perfect Ford Powerstroke tuners so you can give your truck the boost you’ve always wanted.
