Yeah that's a little strange. I wonder what's goin on. I wonder if timing has anything to do with it, because you did notice a change after your workaround.
see this
Make sure you have location permissions for the app, also try connecting with the engine off ignition on and see if it changes.
the trims are just around +-10% around 1. So the system is working,and afr at idle is on target. Under load its more or less good, a bit rich imo.
I think most guys who are getting this kit are expecting it to simply be as advertised, plug-and-play and drive away. I don't have an ngauge and I presume most don't either. so we can't monitor or log under load.
You don't need an ngauge. $20 Bluetooth obd2 device can log trims and lambda.
i actually have one of those with torque pro app. didn't know it logged.
Almost for sure your location permission. Go to the app setting on your phone and pic that one and enable all permissions. I had a similar problem.
