Adrian, you've got a comm's error, try disconnect, reconnecting the cable and a connect sequence (similar to "have you tried switching it off and on again?"), then see if you get the same readings after a few minutes warm up. In addition, you have a Tornado chip fitted (R3116).

BTW are you related to Gavin?

Hi,

Sorry took this screenshot after disconnecting the lead, reading are coming through fine.

Just wonder about views on the "long term Lambada readings" ? - yes- Mark Adams chip

Thanks

Its not the end of the world by any means, but it does mean the ECU has had to make some quite large adjustments to get the mixture correct at idle. The nearer to 0 % the better, as this means the sensor readings and map is spot on, but its not a real world condition as the left and right banks of the fuel map fuel slightly differently even with every thing perfect. I would not worry about it if the cars running OK- its when you hit 100%- then you have a problem.
