it will stop any o2 adjustment are you using a standard ecu or something else on the power fc you can remove the lambda sensor and run without it just fine, its really meant for switching around stoitch to give better fuel economy but it can mess up peoples tunes sometimes

thank you loz they did remove it cause they could not map it right
they told me their explanation was that when the lambda went into closed loop it was leaning out the map so they unplugged it and disabled the feature in the Power FC


just was hoping my engine is safe

do i need to plug it back in for m.o.t ?? thx again

they did not really need to unplug it just disable it in the power fc, it alters the fueling by itself to give you the best economy etc so when you try to map there it mucks it all up

as long as your afrs are ok you dont really need to re-enable it but you might get a few mpg more you cant re-enable it in the pfc without a datalogit or similar i think

This shouldn't be a problem at all if setup right.
