Kpro PRB open loop no A/F in display datalog

Hi, I have a rsx 02 with prb ecu. I wanted to make a datalog and adjust fuel values but when I have the wideband settings on open loop it doesn't show anything.
Anyone knows how to see the A/F ratio?

Post the calibration file and datalog. Are you using the OEM wideband or do you have an external wideband? The settings might be wrong.

I have a denso wideband in stock wiring.
I am on my Phone atm dont have access to the calibration and datalog from here.
I have checked for any setting but could only find for external wideband.

Post the calibration when you can. I might know the issue but I need to confirm with your current settings.

Hi, here is my calibration. My datalog is on my laptop and I don't have it near me because I forgot in my garage.

If you are using the built in wideband you need to select "Built in wideband - PRB, PND, PNF" under the Closed Loop Operation. You also need to zero out the trims so the o2 sensor does not correct while you are trying to tune.
