в этой прошивке затерты ошибки. У автомобиля есть проблема- при полном газу уходит в аварию и до 3000 оборотов. При диагностике star diagnosis ошибок нет(( Вот я и ищу оригинальную прошивку что бы понять что не исправно. Если кто может помочь,то поправьте эту прошивку.

Errors are erased in this firmware. The car has a problem - when full throttle goes into an accident and up to 3000 rpm. When diagnosing star diagnosis, there are no errors ((So I'm looking for the original firmware to understand what is not working. If anyone can help, then fix this firmware.
