My wideband guage reads with the stim but not from my plx unit. The plx is also connected to a guage and it reads fine. I called plx and they gave me over the phone troubleshooting help and determined the unit defective. So since the unit was used I purchaced a new module and belive it or not still nothing. So if anyone has a suggestion let me know.
Thanks

 

Well fixed my own problem. Crossed a wire works now. Anyone need a plx sm-afr sensor module and wiring?
