Our company produces a complete software removal of catalysts with the subsequent adaptation of the lambda probes for BMW cars. After this procedure, the car functions correctly and without errors.
What will happen if after physical removal of the catalysts they are not removed programmatically?
1. On the instrument panel, a Check Engine error will light up.
You can ignore the error, but then there is a risk of missing a more serious notification of your car about engine malfunction, since the check will always be on.
2. Car emergency mode after removal of catalysts
In the case of physical removal of catalysts, the engine ECU determines that a malfunction has occurred in the system, which in turn entails the activation of the emergency engine operation mode. In this case, the power of the unit decreases, the maximum speed decreases, etc. to prevent engine failure. As a result, it becomes uncomfortable to drive such a car.

When programmatically shutting down the catalysts, there is no need to install various snag and emulators, which, by the way, quite often cease to fulfill their function.
We reprogram the engine ECU and turn off the catalysts.
As a result, there will be no errors in the system of catalysts and rear lambda probes; the air-fuel mixture will be prepared correctly.
