370Z CAN Bus Proprietary PID's

Fantastic progress guys!

I've been away from this project but am back on board now. If there's anything I can do let me know

I've got an Android tablet in my 370Z now. (I might be repeating myself here...) Mine is an early one without Connect Premium. I'm doing it like this:



I've hit some problems with the whole USB OTG and power combination as well as standby power issues but I'm getting there slowly (see here).

So I'd vote to go Android!

I had these same issues (though with a windows tablet) and think I finally solved them. (incredibly annoying)

1) I found an OTG USB hub that takes external power, and powers both the tablet + peripheral devices, with a built in relay. It needs to trick the host USB controller though, so only works on a few specific models of tablets.

2) USB chargers suck, and USB cables suck. at 1A of power, if you have even 1 Ohm of resistance in all your cabling and connectors, you're only getting 4V at the end. Even with the best cables I could find, I was only getting ~4.6V at the tablet, and that wasn't enough to make it charge. I ended up solving this from both sides:

- I made my own USB cables using 18Ga wires
- I got an adjustable buck converter, so I can run the source at 5.25V, and then it's still 5.0V at the tablet after all the losses.
