Dashlogic Users -- OBD2 Splitter Question
I currently have an AEM OBD2 passthrough and HPTuners MPVI2 connected to my OBD2 port. I'm wanting to relocate the HPTuners module as well as potentially run a Dashlogic device. I'm going to get a relocation splitter, but was curious if anyone else had gone down this multidevice route? Will both devices function off of a split signal? I could just swap modules when I hop in the car to do some tuning, but I'd prefer to keep both devices connected/under my seat as long as a split signal is not going to cause issues. Appreciate any feedback.

I am in the process of hooking up the DashLogic along with a PLX 'SM/AFR module' that includes a wideband O2 sensor so I can monitor my AFR on the car's DIC display.
I also have read that if you want to hook up the HP Tuners, you need to disconnect the Dashlogic from the OBD2 diagnostic port.
It seems that you can't correctly run both at the same time by using an OBD2 diagnostic port splitter cable.
It's either one or the other ... but not both at the same time.

Do you have a separate thread on this install ?

I decided to just get an OBD2 extension cable and will relocate the OBD2 port to the glovebox (which is where I already keep my MPVI2 when I'm not using it). Will just swap between the Dashlogic and MPVI2 when I'm out tuning. So my daisy chain will look like this: factory OBD2 interface-->AEM WB passthrough-->10ft cable-->MPVI2 | Dashlogic.
