Many motorists were faced with the fact that it was necessary to flash an electronic engine control unit (ECU). This may be a forced operation, due to the fact that the ECU can no longer reset errors, or, at the request of the car owner, chip tuning. But, in any case, flashing the engine control unit is a rather laborious process and not everyone can do it.
The video will tell you how to independently flash an electronic engine control unit, and also tell about some of the subtleties and nuances of the process.
Probably, many motorists remember old cars, where all controls were carried out by mechanics, but with the development of the automotive industry and computerization, these two industries increasingly began to touch and connect.
Not everyone knows that car control units appeared in the distant 80s in Japan. They were the first to be mass-produced in Mitsubishi trucks and were responsible for safe braking. These were ordinary boxes with a microcircuit, which, depending on how the wheel brakes, changed these modes.
In the mid-1980s, General Motors is installing the first electronic engine control units on a number of its muscle cars for the first time. At that time, it was considered a breakthrough in engine construction, but already at the beginning of the 90s, many automakers began to equip cars with this device. So, many CIS motorists remember BMW and Mercedes-Benz with a bunch of electronics under the hood.
It is no longer possible to imagine modern car manufacturing without the use of ECU. This mechanism controls the operation of the power unit, as well as part of the on-board systems, warns and indicates breakdowns, but it itself can break down and will require repair and restoration work.
In world practice, several generations of electronic control units are shared, consider the main ones:
