I suggest first checking if there is a fuse in your car's electrical system that is only for the Start/Stop system. If so, simply disconnect it and check how it affects the car and if it does what you want it to do. This may be a better solution than changing the original car setup.

I tried with MED40 and CRD3 but can't connect to ECU, only with command 27 01. It works for me because I have old ECU.
