I have been installing gauge mod's to my 2008 MCS R56 over the last several months.
Have added a PLX Kiwi 2 WiFi system tapping into my OBD II and using my iPhone with DashCommand for visual feedback of data.
My gauge's added are: 1 Marshall Boost Gauge (Soon to add a PLX Vacuum / Boost Sensor Module), PLX DM-6-Wideband AFR (UEGO) gauge combo for Air/Fuel Ratio and 1 Oil Pressure Sensor Module.
My problem is PLX is closed for the holidays and the Oil Pressure Sensor feeding the DM-6 is showing "0" PSI.
The DM-6 shows the AFR data and the Oil Pressure data (except no feedback).
The wiring according to PLX install is for two cables connecting from Sensor to the module by way of wire (Bottom of sensor to module 1 bottom pin) and top screw (Ground) to module 1 top pin.
The second screw connector is for optional alarm marked "W" on sensor and is not used.
Any idea's what I may have done wrong or is it possibly a bad sensor?
Thanks for any help.

 

Follow up: I talked to PLX Support and they recommend moving the power line to a more reliable source.
The DM-6 gauge sometimes shows gibberish and not the clean readout. It also occasionally turns on when the car door opens.
Anyone know the best line to tap into for 12 volt power other than the lighter?

I still can't get live information to to pass through the DM-6 for Oil Pressure, but can for my Air/Fuel. The readings are good for A/F, but when I scroll to the next module (Oil Pressure) I get a 0 reading which translates into the PLX module is working, but the sensor data is not being passed. Rewiring for better power and checking the two leads for the sensor.
