Wideband doesn't read 14.7 in CL Hi,
still trying to get my head around this one.
I have LS1single turbo.
My NB 02 sensors are installed in each bank of my log headers.
My WB sensor is in the downpipe.
I have tuned all 've and wot to my wideband.
the fuel in the UK is E5 99 (US equiv 93).
I have used the NBs as get heat soak at idle so have switched them on for low throttle cruising cells in Efilive COS3.
so get CL tuning with NBs for those areas.
Now when I am in CL my WB shows around 14.4, 14.5.
Does this sound correct for E5 fuel.....?
if so at wot should I be targeting a lower afr than 11.5 or higher or neither....with my WB?
I have tried changing 02 switch points NBs to lower than 450mv to 200mv to get my WB to read same as NB
so confused....

What kind of wideband?
Are you looking at its display or what it reads in the data log?
I’m not familiar with EFI Live data logger.
I use the Ballenger (NTK) AFR500 and the screen shows 14.5 but the data in the log is 14.7.
