Whenever you buy a diesel car, you are probably considering its good points. You are aware of you're ending up with a trustworthy vehicle which is meant to last and reasonable to drive. Conversely, diesel vehicles have their own share of negatives. Your car or truck is more than likely a little bit noisy. You have to put up with slow throttle response and uninspiring performance. But hang on -- here's some good news for you. Diesel tuning can certainly improve your reliable but stodgy car into something far more exhilarating and gratifying to drive.

The easiest way to carry out diesel tuning on modern motor vehicles will be to customize the software in the engine control unit, or ECU. The ECU handles every aspect of engine operation, processing signals from a variety of sensors and informing the fuel injection system how to proceed. The ECU's software programs, or maps, handle fuel delivery and timing so your engine runs efficiently at any RPM and pollution levels stay within acceptable levels. The early era of engine control units kept their maps on a removable computer chip. Current ECUs have built-in maps that could be accessed via the On Board Diagnostic port.

Diesel tuning involves rewriting the ECU maps to liberate a diesel engine's true potential. A wide selection of settings that affect the overall performance of your car are improved in the remapping process. The aim of ECU remapping is to achieve the optimum power curve for automobile performance and fuel economy. Simultaneously, safety parameters originally programmed to the ECU must be respected to avoid any harm to the engine or drive train.

Diesel engines by their very nature possess a lots of space for performance enhancement. With a high compression ratio greater than 20:1, cylinders in diesel engines incorporate more air than necessary for normal fuel combustion. Should you remap the settings in the ECU to elevate fuel injection pressure and make better utilisation of the available air, you can easily boost engine power and torque.

Properly undertaken, diesel tuning by remapping the ECU can make the engine run more efficiently, delivering even more power and torque. Take, for instance, a late-model Audi with a 2.0 litre TDi engine and original power output of 140 BHP. Remapping the ECU could easily boost power to 170 BHP and increase torque by 75 Nm. However, power gains vary, based on the model as well as engine specs. Nonetheless, a 35% improvement in overall performance is practical for many vehicles.

Following tuning the diesel car, you can expect to enjoy a smoother, quieter ride with more immediate accelerator response and peppier acceleration. The engine will give you more consistent power delivery with fewer gear changes and less throttle needed for any kind of driving. The engine lag and irritating flat spots that are so characteristic of diesel cars will vanish.

Supplemental power and torque has realistic uses, too. Stop-and-go driving while in the city will be needing less gear changes and less braking and accelerating, that results in fuel savings. Higher mileage individuals will likewise see much better gas mileage from better fuel combustion at increased travel speeds. If you need to tow a vacation caravan or another heavy load, your freshly tuned car or truck has the additional torque it needs to keep up with traffic and pull more safely.

Whichever company you decide tune your diesel car will need to possess the most current ECU tuning equipment and the right skills. Don't think about trusting your car or truck to one of the cheap service providers. Technological innovation in new motor vehicles changes so fast that companies must continually revise their tools and software to maintain pace, and you can bet which costs money. Get your car tuned by the true specialist and you'll have no misgivings later.

For anyone who is aggravated from the personality flaws with your diesel car, diesel tuning can quickly enhance its power and performance, making your vehicle more pleasant to drive and costing you less on fuel. Because there are many plus points, it's no surprise that an ECU remap is really a preferred vehicle modification for diesel owners.
