Hp tuner vcm suite not seeing o2 readout
OK so im not new to tuning,but i am new to the platform.
i pulled the trigger on the vcm suite and have done several logs already but i get absolutely no reading on the O2 sensors. they should be between 0 and 1 correct?
Am i missing something, because i do not have a DTC, and have both factory O2 sensors.
ANY HELP IS GREATLY APPRECIATED.
also searching for similar issues hasnt gotten me any results. IF I overlooked existing information, i apologize.

The #1 O2 sensor is wide band on the SS, so not the same. It is measured in Hz
#2 should hold steady around .6V, doesn't matter much as long as steady.
I don't know much about the SS and nothing about VCM suite.
I know my OBD2 reader could read the data on my 2.2L with no messing around.
changed broad band to wide band(thanks DrLoch)

Go here https://www.hptuners.com/forum/showt...357-LNF-Guides. Lots of reading.
It is a wide band.
Whatever you learned about tuning doesn't apply to an LNF.

MANY THANKS GUYS!!!
So i knew that being a DI engine it had a Wide band sensor, so far i have found information for the how to obtain the information from the primary (upstream) o2 sensor and i have already made 3 decent tunes for the car, right now im only worried about the a)auto trans; b) those pesky ring lands being im peaking between 24 and 27 psi....
seems like the car just keeps gaining boost if i lay into the throttle. its a whole new animal from the GMS1 to what it is now. Couldn't imagine the car being stock, i need to take it to a dyno and see where im at with this setup
