Diesel Tuning

The ABC of Diesel Tuning

Diesel tuning generally refers to enhancing the performance of a diesel vehicle. The amount of extra oomph you gain depends on your vehicle and when it was manufactured. But to explain diesel tuning properly, we’ll have to start somewhere close the beginning…

Diesel engines combust the fuel-air mix by putting it under pressure. These engines burn fuel at a slower rate than petrol engines, and offer a higher torque at the same time, which means they have a bit more kick than a petrol engine – typically the reason why you’ll see more diesel-based farm and construction vehicles than their petrol-based counterparts. That, and the fact that diesel is cheaper than petrol.

Diesel tuning in old models (usually pre 2000) requires the physical manipulation of engine parts. High pressure fuel injection systems can be added to older vehicles to inject a relative high charge of fuel into the cylinder. This boosts the vehicle’s power. Fuel warming and high pressure injection rails can also be added to increase a diesel’s power. Sadly, however, these steps are all quite costly, and the amount of extra power you get isn’t worth writing home about.

Now enter your post 2000 vehicle models. These have all been manufactured in this millennium, and have the technology to prove it: an entire electronics system controlled by an ECU chip, or electronic control unit. The ECU controls virtually everything – from the inner workings of the engine to the airbags, ABS system and so on. And this is where effective diesel tuning comes in.

Diesel tuning is usually performed by an individual who knows his diesel vehicles inside and out. Unlike the manual diesel tuning described above, electronic diesel tuning can enhance a number of things related to a diesel vehicle; most notably power output (which can be up to 30%), fuel economy and also how the vehicle handles on the road (or wherever it is driven). A diesel engine’s performance can be further enhanced with nitrous oxide injection.

But just as with petrol engines that have their chips tuned, there are some considerations which should be taken into account with diesel tuning: to increase a parameter in one part of the engine, another part will have to make due with a little less. And while you may be saving money on fuel, you’ll be spending more money on maintenance and services because diesel tuned engines have to be serviced regularly. Your vehicle will also be more fussy – low quality fuel won’t be tolerated.

That being said, diesel tuning is perfect for individuals who need more power out of their vehicles to achieve a specific aim, or who operate the vehicle in an area where a tuned ECU chip will make for better driving. And since modern diesel tuning relies on electronics, you’re free to change the settings of your car whenever it is necessary at a relatively constant cost.
