New o2 Sensor

[gophishy10]

My o2 sensor is shot and instead of getting a $80 new oem sensor, I want to go with a wideband since I will be doing a 16g upgrade soon. My question is if I already ordered a 3 pod gauge pillar with gauges (including a afr gauge) can I just get a wideband sensor? Or do I need to get the whole kit? Is there other parts in the kit I will need besides the actual sensor?

A wideband is a complete AFR measuring tool which is basically a gauge with its own O2 sensor. It can't be connected to a narrowband gauge (likely the AFR gauge you ordered) which is meant to read the factory O2 sensor. A wideband also can't be used in the front O2 location without running "narrowband simulation". This can be done through either a tuning device or by wiring the wideband into the front O2 signal input. But this is only if the wideband has a logging/narrowband output so research thoroughly before buying.

But for now I would replace it with a factory O2. I suggest oxygensensors.com for great prices on OEM sensors. Id also advise you to search the differences between a wideband and narrowband gauge.

Well won't I need a wideband once I do the 16g upgrade (with 255 fuel pump, new injectors, fmic) to properly tune it? I have SAFC just not installed since there's no point right now.

There are some widebands on the market that have a narrowband output from the controller that will allow you to run it to the ecu.

You should buy this EXTREME PSI : Your #1 Source for In Stock Performance Parts
and EXTREME PSI : Your #1 Source for In Stock Performance Parts. If you don't have enough money for both of those parts go to your local parts store and get an o2 sensor for now. Get rid of the afc and start saving up for what you really need.

Like the Innovate MTX-L I love mine, I ran the narrowband simulation on it for a while and it works great. An AFR gauge that comes in a kit is more than likely going to be a narrowband, which is pretty much useless besides telling you your o2 sensor still works. If you do use the SAFC please make sure you have a good data logger to go with it, I've seen too many engine failures from bad SAFC adjustment

True, totally spaced on that. Most quality widebands will have a 0-1v output wire that can be hooked to the Front O2 ECU pin to simulate the narrowband sensor.

Yes, you will need a wideband for tuning. But it's not required that you replace the front O2 with the wideband sensor, it's just less work since there's no need to weld in a new bung.

Thanks for all the input. I think I'll go with the MTXL Innovative Wideband from Extreme PSI. Seems like a good value. Spoolin, I would get it professionally tuned. I wouldn't take a chance of messing something up by doing it myself.

The wideband made by aem also works with the ecu.

 

[gophishy10]

One other question...would the datalogger that comes with that wideband be sufficient for tuning later on? Or would I need anything else?

just save up and buy dsmlink..you won't regret it

+1 on ECMlink. It was my first upgrade on my car and I love it. Worth every penny even on my car when it was completely stock.
