Flashing — or erasing and reprogramming — your engine’s computer is a legitimate way to keep a car’s engine control modules (ECMs) up to date. Cars newer than 1996 should have this done in order to make sure that microprocessors such as the power train and fuel injectors work the right way. If the programming is optimized, your car’s engine tends to run much more efficiently. It’s a bountiful cash crop for repair shops, who tend to charge between $ 80 and $ 120 for the service, as outlined by Under hood Service. Your car can be flashed by you if you have the right equipment around.

How to reprogram an engine computer
Under the steering wheel within the car is a diagnostic port in a car which needs a scanner attached to it when reprogramming an engine computer. The auto manufacturer has put new programming into this scanner which erases the old and replaces with the new. It used to be that it was necessary to remove parts in order to complete the reprogramming process, but now all that’s necessary is a computer with an Internet connection, a USB cable and a scanning device that can connect with a car’s diagnostic port. The ECM is flashed with the new software direct from the manufacturer’s site.
When an ECM should be flashed?
Auto repair shops say flashing should be done once each and every few years, and this may be appropriate. However, it’s typically only something that needs to be addressed on a need-to basis, unless a sweeping pronouncement is issued by the manufacturer as part of a recall movement. Routine maintenance shouldn’t include flashing when doing anything else to make certain your car works.
Getting the job done with DAY flasher
It is simple to do usually. Consult with your automobile manufacturer’s website for software updates. A flash programming device is what you’ll need to download the update to. Additional software for proper engine tuning may be necessary. Consult sources such as DIYEFI.org for more specific details. Before doing anything, your state’s motor car authority should be consulted considering states like California have touch emissions testing making it illegal to do some different engine reprogramming.
