Setting up a tablet is the easy part. What about multiple tablets? The ecu is a 2008 e38 from an 08 Express van. Can multiple obd2 ports and usb adapters be used? Been searching around quite a bit, and getting conflicting info.

Thanks

 

Yes you can
However, it will slow down the data rate if you scan a lot of PIDs
You only need to extend the CAN network and add another diagnostics port. Watch the location of the network terminator (resistor)

 

OK, thanks for the info. I was planning on using obdlink usb adapters until I since figured out that the cable does not provide power to the tablet/ phone, and I don't think I want to mess with multiple bluetooth. So my new plan is to use the speedhut can bus gauges, and one tablet where the radio was.

But for whatever reason, it says they cannot be used with any other obd2 device. I think it can be?

Wired like this?
Can bus wires from ecu(resistor) into and out of a dlc port, into and out of another dlc port and then to the tcm(resistor).

Would that work?

So it would be 5 can bus gauges, and then the tablet monitoring an additional 6-10 pids. Is that too many? I dont want the speedo and tach stepping if they can't sample fast enough.

Thanks for any help!
