Can someone help me interpret my Tuscan diagnostics please?

[Technoholic]

As part of ongoing restoration work I'm using EvoOlli's great software to examine my engine on the Tuscan. As you can see, the adaptives are way out, and the AFR 123 sensor is red. If I reset the adaptives, the engine sound changes massively, I think for the better, but that only lasts a few minutes before being back to the same. The adaptives get to this level within about 30 seconds to 1 minute.

Can anyone help point me in the right direction? Thanks

Also both fans were on at the time of these readings yet it says OFF. What should I be looking for here?

Reckon you've got badly adjusted throttle bodies on front bank...or...you have an air leak on those bodies to the head. Try putting you hand over each body mouth in turn for 20 or 30secs and watch the adaptive...does it start to decrease and does the front bank lambda start to ping pong between 0 and 1 v
