What do you mean as I don't reference either as I use a wideband for true lambda calculations then after the tuning is done the factory o2 sensors are only there to maintain the target lambda set by the tune ( +/- 0.02 lambda swing ) 

 

what exactly do you want to know ?

Just curious as my 2nd o2 sensor has never been connected. I realise now my dislexia (derr) took over when I initially wrote the post. I meant "does the ecu only use first o2 sensor for reference after flash?"

It's common for tune shops to turn off the 2nd o2 sensor especially when a big cat has been installed ;)

That explains that then. To me it seems useless anyway - why have another sensor downstream. Ive logged it and its exactly the same reading, just slightly delayed.

 

Also, @JETURBO do you know of anyone that can supply higher flowing versions of the standard 4bar bosch fuel regs?
