afr wide band to ecu

[KEVTI]

Hi guys, i just got a chipped p30 for my b18 c and im looking to get an inovate afr gauge so i can map it ect. The question is, does anyone know how i can connect up the afr wideband to the ecu so that it replaces my std narrow band sensor ? I need to do this so that i can data log the afrs through the rev range.

New to tuning so any help is greatly appreciated

Cheers

Would you not just have to get a ecu wiring diagram and hard wire the wide band in? Will need to be doing this myself at some point as im just using the gauge at the moment so intrested to see what replys u get.

something like a PLX will have a wideband output and a simulated narrow band output too. stick the narrow band simulation in the std position and use one of the extra inputs to log the wideband.

im not sure because obvs a wideband is 5 wire and narrow is 4 so i dont think it would be that simple.

What is a plx ? I have a moats xtream hulog data logger which just connects strait to the ecu

On obd1 harness wire brown wire from lc1 to d10 pin and yellow wire to d14.

what about the other 3 wires on the sensor then ? I dont have pin data so im not sure which wires those are

ahh i see, have you done this yourself ?

This is the gauge im getting, INNOVATE MTX-L: Wideband Air/Fuel Ratio Gauge. Will i need the lc1 as well ?

yeah same as above both inputs wired to ecu and i no longer use the oem lamba sensor

ok cool so do i need that lc1 or will i be able to connect the gauge to the ecu ?

Cheers for your help

no you don't need lc1 as well the likes of mtx below comes with everything

ahh awsome thats the one im getting, now i know that i cqn connect it through the ecu makes life easier, and it will data log the afr. Thanks for your help mate, i will me asking alot more questions soon to do with tuning haha
