HI..
ihave buy the plx device SM-AFR+ DM5 COMBO for see the af/ratio in my euro civic type r with PRA ecu..
i have race header...
can i put the wideband sensor in the SO2 hole and wire the output 0-5v in the wire of so2v to see in datalog the 0-5v ??
what is the color of the wire in the so2v to put the 0-5v signal?
i have 2 white wire(think heater)
1 wire grey( ground?)
1 wire black (signal to ecu?)

You can do this only if you use the narrowband input to the ecu. I'm not familiar with the Euro wiring so I cannot tell you what pin to connect it to, but you should be able to find it by looking at a Helms manual. You will not be able to datalog the wideband readings in the software at this time.

i can't see the voltago 0-5 v in so2 v???
i wire the output 0-5v of controller plx devices to so2v..?

This will only work on a PRA, and you must input the narrowband signal into the primary o2 input.

spunkster..
i put the output narrowband to O2 primary, and the output wideband to O2 secondary?
the car work fine and i see in the datalog so2v 0-5 v?

contectr, on my Civic I use the stock narrow sensor on the first Input, and I use the 0-5volts signal from my AEM Wideband for the Second O2 input.
