half... bro, it’s likely you’ll keep working on it, and, sometime in the future you or someone else will come up with a new revolutionary solution that’s better than what’s gone before, you just don’t know it yet.
Consider the cruise retrofit on a //M never never land story: for over +10 years all I ever heard was:
- it’s almost impossible & certainly not cost effective
- requires coding
- requires new throttle body & revised ECU
- the wiring is totally different & not compatible
- whoever got it done by BMW had their wallet bent over a barrel
... & then enlightenment, with one extra wire connected to an unconnected wire in the ECU & a standard cruise loom, sorted simply & effectively by the FF’s ;@)
Good hunting
