Afr advice please

[dalegolf215]

Hi guys
ive already searched and cant find what im after
so here goes

when reading my AFR it never goes below 13.5
and is always between 15 and 13.5
it doesnt seen to be even slightly linear and its like its just bouncing between these figures
even up near to redline

any ideas what this suggests guys
BTW no fault codes either

thanks in advance

What wideband setup do you have?

Im not 100% sure what wideband even is (somesort of standalone gauge?? )

thats reading from a graph on my liquid gauge
just taken from obd port like vagcom readings

Ahhh, thats the problem, narrowband ECU on the ibiza, wont show lambda readings correctly.
