What is “Reflashing” or “Flashing”?

“Flashing” refers to reprogramming automotive engine control modules (ECMs). Almost all new vehicles today are now flash programmable.

It is the process of downloading raw data from the factory (OEM) ECU through the OBD2 port, manipulating the necessary data/maps on a laptop or PC using specialised software, and then ‘flashing’, or uploading, the altered data back into the OEM ECU.

Computer reprogramming is an important part of repairs and tune-ups on most 1996 and newer cars. Many times, reprogramming is the only way to repair a vehicle and eliminate false “Check Engine Soon” lights or MIL indicators, and will often x engine and transmission problems that are not caused by mechanical issues.

What is an ECU?

The electronic control unit (ECU) in today’s cars and trucks is responsible for controlling the functions of the engine and other components. An ECU is a device similar to a home computer or laptop that has internal pre-programmed and programmable computer chips. The vehicle’s engine computer ECU controls all engine functions by using input sensors and output components.
