I'm concerned that there is no connectivity to my 02a sensor. I can see voltage on my 02b sensor, as shown in the attached picture, but I've never seen any voltage on the 02a sensor. Can anyone else confirm they can see voltage on this sensor from their flashpro? I swapped the sensor for a new one, but no change. As you can see from my long term trim (stft is also +10-30%) it is way high, I'm very lean. I've checked for leaks on the intake, and checked my vacuum lines - everything seems to be okay. I'm open to advice at this point. I'm also attaching the last datalog that I did, please take a look if you get a chance, there may be something obvious to someone else. Thanks, guys.

Not all channels can be datalogged for all vehicles, so o2 voltage and map voltage are not shown for your vehicles.
A lean condition is perfectly normal upon overrun injector shut off.
However in your case the trims oscillate and the long term trim is very high. Are you sure the o2 sensor is correct? Was it from Honda?
