    Wideband Tuning Issue

    I've had this software for awhile now, but i recently installed the NGK wideband sensor and module made a config and began scanning. I let the sensor calibrate for several minutes, took it for a ride and AFR was +/-5% AFR error. I copied and paste VE table by % half. i took the car out for a ride this week and i am getting a -20% AFR error. I reverted the VE table to before i changed it, and also re-calibrated the sensor but it was ok and needed no adjustment. I took the car out again and logged, i am still getting -20% Error. Both logs are in the same tune of SD mode to try to get the correct readings for AFR. Im an unsure why i am getting such a huge swing on AFR Error. Going through between the logs, i noticed the KPA value was around 58-62 at idle, when it is usually around 48-52, as you can see in the 2 logs. If anyone has any insight on to what i may doing wrong, i would appreciate it. Thank you

    Was your wideband in the open air or in your exhaust still when you calibrated it?
