There is not much support on Simos3 and other ECUs from small cc engines.

From my experience, to avoid P0420 DTC you can install the O2 sensor on an elbow

I make my own out of stainless steel. This solution works 9 out of 10 times.

P0441 is a different story

Mate, i don't like this dump, it seems to be partial... how did you read it?
If you want DTC off, the dump must full.
