ok i read a bit about installing a wideband o2 sensor and gauge, now where exactly should i install it? should i take the stock front sensor out? or should i weld a bung in front of the cat on the y pipe? im not 100% positive on what i should do with this. any help appreciated =]

 

No you need your factory O2 Sensor.

Install it before the the cat, mine is in the y-pipe right near the stock O2 sensor, they recommend that you install it above the 3 o'clock position on the pipe to prevent moisture build up on the sensor, I didn't know about this at the time I installed mine, mines at about 4 o'clock and no problems yet.

 

okay thats what i thought, ill have to do that then. thats not a problem, i just wanted to make sure before i did it and ended up doing it wrong lol

 

THe one I got, cheapest price for the Auto Meter 3379: $188.00

It is 238.99 on summitracing.com

PLUS A MANUFACTURER'S REBATE!!!: $40!!!!!!

BTW, what gauges do you have in your triple pillar pod? I only have a dual pod for AFR and Tranny temp. Could not think of a third one I would need.

 

trans temp, air/fuel, and i had a boost gauge incase i turbo'd it BUT im prob switching it to a mechanical oil pressure gauge very soon

 

I have mine right before the cat as well. Only other option is getting 2 and having one in each pipe

 

I only have one AFR gauge and it is on the odd# side (Drivers side). I have a cali truck and I have 2 precats before the Y. So I can not have it before the main cat where the Y meets. I also have 4 factory O2 sensors. THat is gonna suck when they go bad.

You can have it on one side only.

 

Not sure if that's in reference to my post saying I'm wrong?

There is setups where you run one on each side. That's actually better because you get each banks reading separate. I found it overkill for the truck though beings both pipes come together. Now if you're running true duals it would give you better readings.

 

There's two different topics comingled in here and, it should be clarified that, wideband TUNING is different than that of wideband A/F metering.

The former is used to measure just about everything on the vehicle while recording every sensor input, logging it, and making it available for review at a later time or, real time- users choice. The sensors that are available are all sensors including EGT, PSI, MAP, IAT, Mass air, TPS, IAC, A/F, Oil, Fuel, and tuning PER cylinder plus speed sensors, and, if you've got a compatible ignition control system, that too can tie into one system (providing it can communicate and, it is compatible software and driver wise)

The latter is a simpler, less costly method of a one-size fits all approach for simply measuring the A/F ratio on an AVG basis, then, with that data, feeding that to into your software program to customize the fuel trims at the programming level.

Either method, either a programmer does this or, you go out and purchase the software and do it yourself.
