no, consult will give you oem narrowband afr data, which is useless if you are not a computer. It can only say "lean" or "rich" as basically it outputs a signal between 0.2 and 0.8V. That is enough to make a fine adjustment, like in a closed loop system used in a car, but no good for tuning. A wideband lambda sensor outputs a 0-5V signal which gives you a very accurate result. It really is very useful, not only for tuning, but it helps see when things go wrong. The problem is you usually need to have a bung welded on your downpipe to install it . I am using a PLX one too, but would have went VEMS if i could at the time i bought it... Nearly all wideband kits use a bosch LSU 4.x sensor. the VEMS system is "better" because it has AFR and EGT on the same gauge, so that is 1 less gauge on the dashboard
Imho you have a wiring problem or a dead sensor. Can you try wiring it yourself ? A narrowband sensor is not that difficult.
