You know how remapping the ECU will increase your automobile's performance: more power and torque, better handling, better fuel economy. Now all you have to do is hire a company to do the work. You'll likely notice that some organizations promote tailor made or bespoke maps and other companies focus on working with library maps. It is important to know the difference between the two forms of remapping. Bespoke remapping can be more expensive, but it has critical advantages making it worth the price tag.

Bespoke or custom remapping begins with the file which is in the car's ECU at this moment. The specialist downloads the original ECU map from the car and after that modifies components of it to enhance engine performance. The files for numerous distinct systems are updated with pricey software applications. The technician must realize the best way to recalibrate every setting -- basically, he has to understand he's doing.

As well as the maps that manipulate fuel combustion, the ECU also contains data relevant to the motor vehicle for example immobiliser details, software revisions, bug fixes from the manufacturer, and so on. Due to this, just the files that need to be altered are touched through the remapping -- other vital data about the car is left unchanged. After that the map is flashed back to the ECU, overwriting the existing file. A backup of the original ECU file is held by the service provider, just in case. Bespoke remapping is always customized to your individual car or truck, which provides the best achievable results.

Remapping with a library data file is quite different. The tech will not use the original ECU file from your current car. Rather, a revised ECU map is chosen from a assortment of potentially 10,000 generic files. The library file is copied back to the car's ECU, overwriting everything -- which includes just about any vehicle-specific info that can have been on the original file.

Now, this assortment of library data files could possibly have a shady past. It is made up of ECU files that someone collected from unknown origins, copied to a DVD, and sold for a few pounds over the Internet. A number of, if not almost all, of the ECU files could quite possibly have been taken from professional remappers. As a result, you truly don't know anything at all about the quality of the files or how they may affect your engine.

Remapping the ECU with a library file is a blunder that can easily have terrible outcomes. The library file probably won't possess the immobiliser software that keeps your car or truck safeguarded. It isn't going to have recent software updates or crucial bug fixes. And let's not fail to remember that a service provider utilising library files possibly cuts corners in many other ways, with cheap equipment and bare minimum technician training.

What happens when you switch a vehicle's one of a kind ECU map with a library file? Without doubt the engine might output extra power after the remap, but there is hardly any guarantee that the enhancement will be what you predicted. Your engine system may all of the sudden acquire glitches and fail to run as it really should. The ECU may possibly freeze up and become inaccessible so you can't even solve the harm. Without having the standard protection functions, your car can be stolen more effortlessly. And hardest of all, you might be required to spend a good deal of money replacing the ECU or fixing the engine.

Since you comprehend as to why custom maps are so much superior than library maps, how do you find somebody to do the work? First and foremost, make sure the firm really does supply bespoke remapping that is carried out by certified techs. It's not hard to tell if you're operating with a professional or a poseur. Simply ask the tech a few questions about how the remapping is accomplished, what type of files he uses, which engine settings are modified, and so on. A qualified and experienced person will be perfectly competent to clarify the finer points of the remapping process to you. And if someone brings up library files or aims to persuade you that library files are just as fine as custom files, cross them off your checklist.

There's nothing wrong with hunting around to compare and contrast prices, but do not make price the determining aspect. This is a high-tech industry and technological innovation costs money. If you find a service provider with very low prices, ask yourself the reasons why. In all probability, they are utilizing library files and cheap equipment for remapping.

You should also reassure yourself about the company's after-sales service. Is there a demo phase after the remapping? Do these people always keep a duplicate of the original map in case you ever need to adjust back? Does the workmanship come with a manufacturer's warranty? Does the company ensure enhancements in BHP, torque, and gas mileage? Make sure you're happy with the replies to these concerns.

Remapping the ECU is an highly effective way to boost engine performance, but if it's not done correctly you really do put your car at risk. There's no question that bespoke or custom remapping is a greater option than remapping with library files. You'll get the most desirable results, and every bit as important, you'll safeguard your expensive vehicle from damage.
