Is it better to stick with a wideband air/fuel gauge or just tap one into the stock o2 sensor?

 

Way better to actually drill and tap a bung into the downpipe between the 10 & 2 o'clock position for an accurate reading.

 

I have an air/fuel gauge already that came with the car and I wanted to hook it up, but it is a direct tap into the o2 sensor....Would that be ok? I know it wont be as accuate as the wideband

 

They're useless and pretty much just for show. get a wideband.

 

Useless you say, so i shouldnt bother wiring mine up the rest of the way? if its not gonna work im not gonna waste time tapping into the ecu again, i just put all my gauges and pod in just need to wire them the rest of the way

 

just go with the afermarket

 

Yea, gonna go with the AEM Wideband

 

the oem o2 sensor is a narrowband, to tune the car and get more accurate readings you need a wideband. Narrowband are used for base calibration from factory.

 

Just finished instaling my gauges today. the AEM's are nice. i need to change out the face plate on one of them, trying to decide with white or black.

I also made a RS 232 cable for Logging, use a FTDI chip based RS 232 to usb adaptor if you don't have a rs 232 port on your PC. The prolific chip set adaptors are iffy i found.

im about to get the aem soon but my question is will it work in the test pipe area, I have a megan full exhaust with ultimate racing test pipe (i was told that might be it) with side spot for an o2 that i have capped off and stock o2 in catback area. or is there a better place for it

 

nashou....those gauges look nice....

 

Thanks jrod,

And to locdizzle yes you can use this in the test pipe area. it is supose to be no closer than 36 inches away from the turbo.

anytime bro....How long was the install?

 

I did them both in about 2 hours. I first had the shop next to my restaurant install the bung for the O2 sensor.

The gauge pod holder is really nice, looks totally OEM .

I think I am going to try to use the 0-5 volt out from the boost gauge to replace the input on the ECU from the stock MAP sensor and then make the changes to the XML file with EcuFlash. Just have to find the right formula and values for the 3.5 bar AEM map sensor.

I think it will work, this way I wont have to buy another MAP sensor to replace the stock 1 Bar MAP.
