Multiple ODBII devices problems

[evann1212]

I have a set of Dakota Digital gauges that read through the ODBII port. I have the gauges T taped to the ODBII port. I would like to Log with the HP tuner with out having to unplug my gauges.
I was wounding if anyone else has this problem or if someone know how I can connect both at the same time.

While the OBDII protocol does support multiple simultaneous tools, very few tools develop that detection. This includes VCM Scanner.

You have to use one or the other at any single time.

Thank you. I guess I will hook up a switch.
