Cutting the motor control wire may not work, it might just stay in the same position since the ECU is controlling the position of the flop by the two wires to the v308, based on the J808's voltage feedback.
If the voltage of J808 goes outside the 0.5 to 4.5V, the motor will go immediately to full bypass mode and drop boost.
I suggest we can intercept the feedback signal and force the flap into a more open position. This way, it might not throw a code and we can achieve our failsafe activation without having to recycle the ignition key.
There are several ways to achieve this by the HFS4. Do you have the car on your drive yet? We can start working on this.

Ok, car is all ready now, system is installed minus the failsafes. Not sure where to start with this. I have all the tools needed if i need to measure the voltages on the valve while the car is running.
