when you unplug the usb do you disconnect/reconnect ANYTHING on the ecu harness/plug? change o2 wire, eld, etc.?

also, are you comparing the datalog to you wbo2 display or are you looking at the wbo2 display with and without the usb?

something to try: disable closed loop. allow the car to idle. watch the wbo2 display.... let it stablize, then unplug the usb. does the display change?

I don't change anything.
I'm reading the A/F with the usb connected 11.5 and 12.3 with the laptop off and no usb.
Have to check the close loop I think is disable

mine does the same thing, but mainly only at higher RPM in the richer areas of the wideband readings, like at close to 7000 my wideband will read 12.0 in boost then when i disconect from hondata it reads like 11.5, and i havent changed a thing?? my PLX and hondata read the same at idle..with the voltage offset -0.1
