At warm idle, 14.7:1. When you stab it, Id expect to see it around 12.5:1 you will get some fluctuations with rapid throttle changes but that's a general target

map from an other car with “close” specifications won’t be enough.
It is either so much off it won’t even hit an AFR of 14.7 in closed loop or it still runs open loop.
Get it mapped or lear how to do it. :cool:

In parameters, fuel trim, add 20% fuel to the overall fuel trim option to make it a bit healthier for now. But yeah, it needs tuned.

What engine do you have and what calibration did you use?

Should I disable open loop
It should be tuned properly first. This is by far too lean if the wideband reads correct and the header is leak-free. After tuning you can setup the closed loop active. So check out if the header is sealed fine and the wideband-header-interface too. If air is inducted into the header by an leaking location of it, the wideband will read wrong and the closed loop controller may get unstable or into oscillation.

I’ll check the header and see if there is any leaks
