I installed my wideband yesterday and messed with it for a good 2 hours before giving up. I calibrated the gauge everything went fine there, then I hooked into my laptop to set it up but the gauge is saying 22.4 in open air and Smanager is saying 18.85 it wont read above 3.81v. I havent put it in the pipe yet because my downpipe isnt here yet but i figure its not going to be right. I tried to offset the voltage as well but I guess hondata wont let me offset it that far because when i get close hondata goes to 7.35.

Its a Innovate MTX-L Plus installed on D14, I have a S300 installed. B20B Non Vtec all stock ECU and everything

Just checked the wire with my volt meter, the wire going to d14 is pushing 5.15 volts with the sensor in open air, but the ecu is still showing 3.81

Use D10 instead, clip r136 and r138 and you should be set. Also make sure you are using the thermostat housing to ground the wideband. This should eliminate the need for voltage offset.

Do you have the voltage to lambda conversion factors correct in Smanager?

not sure where should i check for it

A quick google search yielded...

So it looks like this thing is programmable? You can alter the voltage output you want?

The default setting should work. Just go into Smanager closed loop advanced parameters, and update your voltage/lambda conversion table to match.

EDIT did read the whole post okay i think i got it, it is setup from 0-5v but the ecu imput only accepts 3.8 which is roughly 18.35:1 which i dont plan on running obiviously so it will work but its not gonna register until i get the AFR under 18.35 which is fine, I will test tonight i should have my downpipe back today and can put it on and try it out.
