Congrats! So it again comes to a wire gauge question (use thick wires) and whether a good source of power is needed (it is needed).

Also I see SAMPLES are set to 60, which also helps to distill the signal in all that noise.

Yeah, I think it's mostly a noise issue in the car.

I emailed D5T5 and they will accept the pin to update to your account for configuration changes. I'm just waiting for them to update mine to see if I can do the manual configuration change in the CEM.

They probably have your pin already from here ;)

Wondering how many people are following this thread... I talked to like 30+ folks over email in these few months since the first pin got cracked.

I also just sent my pin to D5T5 and will share some news after.
I want to add extra key and remote instead of lost one.

I just thinking that Vitaliy is right, better to have dc/dc converter 12v-5v.
I had some difference/issues because of power supply and long wires
