Thanks for that!
No surprise to see they use megalog viewer for peeping logs.
I like it so much I have the paid version just for scatter graphs :good:

Thanks for the tip re:megalog, sign me up!

Is 11.8 AFR safe without a proper WB?

No idea about that, the stock a/f sensor is very accurate around stoich to full lean, most wbo2 are very accurate from fully rich to stoich.

11.8 AFR isn't bad, it would be concerning if at full tilt you saw AFR's in the 12's. The stock front 02 sensor is wideband on a 07 to 09 Lib.

The location of the wideband plays a big part in the longevity and reliability of the reading, stock is in the headers/up pipe for 07 to 09 Libs which isn't great due to being under pressure.
However adding a wideband generally puts the sensor after the turbo in the low pressure side of the exhaust, which is best. This is how the front 02 sensor is located in a 04 to 06 Lib with twinscroll headers and turbo.
