Your engine’s computer needs to be flashed, or reprogrammed after being erased, if you would like your engine control modules (ECM’s) to stay up to date all the time. Microprocessors within the power train and fuel injectors have to have this done if cars are older newer than 1996 since the system won’t work properly otherwise. Your engine does much better when the programming is up to date. It’s a bountiful cash crop for repair shops, who tend to charge between $ 80 and $ 120 for the service, according to Under hood Service. Your car can be flashed by you for those who have the right equipment around.

How reprogramming an engine computer works
Under the steering wheel in 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. Back in the day, the reprogramming process involved removing different parts from the car, but now an USB cable, scanning device, and a quite good Internet connection is all that is needed to work with the diagnostic port. The manufacturer’s website has the new software on it which is flashed onto the ECM.
Flashing an ECM?
Auto repair shops say flashing should be done once each and every few years, and this may be appropriate. Unless a recall is issued by a manufacturer on your car, this really only needs to be done when you’ve noticed something wrong with your vehicle. Routine maintenance shouldn’t include flashing when doing every little thing else to make sure your car works.
DAY flashers have to do this
It is simple to do usually. See what software updates are on your automobile manufacturer’s site. The update could be put in a device for flash programming. Proper engine turning is a concern for some which may require more software. If you’d like to get some more info, then check places like DIYEFI.org. 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.
