Hello, I have been using a wideband and including it in my data log information for my LBZ Duramax. When I first started using this setup I had no issues. Within the last couple of months, I haven't been able to get usable data into the Datalog. It will randomly start dropping to zero and showing false data. I initially suspected faulty wiring. I have verified that the connections are all good and I don't have any wiring issues. This took a long time, but now I have finally pinpointed the issue to be the flashscan v3 while datalogging. I have confirmed that I get good data when connecting the wo2 serial output directly to the PC and I can even get the flashscan to show good clean data if I just do the following: plug the flashscan into serial and obd2, then go to scan tool, data logging, display wo2. This will give me good data. As soon as I start a data log that includes the ecm data, that's when I have issues and the afr starts bouncing back and forth to zero.
I'm not sure if this is a hardware issue, or if there was a software update that is causing the issue. Please let me know what other information would be helpful. I've been working at this for the last month hoping I could fix it with simple wiring fix, but that wasn't the case.
Thanks!
