closed loop vs fuel trim and ign trim

[Martgsr]

Since I don't have a primary o2 sensor (only a wideband) i'm running open loop.
But i was wondering, if the fuel trim vs IAT still work ?
And is the ign timing trim work vs knock ? in open loop ?

There cannot be any fuel trims in open loop without a stock O2 sensor.

Ignition is not affected by closed or open loop fueling.
