Hello everyone, I'm facing the following problem:
I removed the catalyst and flashed the Euro 2 engine.
Prior to this, the active exhaust worked according to the following scheme: I start it, the exhaust button is disabled, the dampers are closed, it works quietly, if necessary, pressing the button, the dampers open.
Also, if the button is disabled at idle, the damper is closed and only opens above 3000 rpm.
The open damper was always open and didn't try to interfere with the sound.
Now at idle, the damper is always open, no matter what mode the button is in, it is not possible to force it to close.
If the button is disabled (damper is open), increasing the speed of the exhaust closes and opens after 3 thousand. BUT when the button is pressed, the damper is open at idle, when the rpm is raised to 1300 it closes and opens after 2000 rpm. This happens in any mode.
I get that speaker + sport, damper open,
she herself always closes in the range from 1300 to 2000, why could this happen and what can be done about it?
