Multiecuscan

I have not really used the multiecuscan software much, I used the old FiatEcuScan software the last time I needed to check the voltages coming back from the Lambda sensors and displayed them as a graph. I have a fiat Stilo 1.6 and can not find the lambda sensor voltages in any of the modules.

If anyone knows where they are I would appreciate the pointer

Can anyone help me with this ?

I've also emailed support and not had any reply. I need to graph the output of the lambda sensors to try establish why I have lack of power from the engine.
