or can i just use the secondary o2 bung? i know it will throw a code without the secondary o2 in but will it change the air/fuel while i am tuning it? in other words will it still tune accurately without the second o2? i got a vafc and am going to do a street tune on it with a wideband and just wanted to know this. thanks for any input.

You can get it from your local import shop that knows what that kind of thing is...not the local ricer store.

Or, you can order one from Summit Racing. It's like $5 or $6 + the $8.45 handling charge. Not worth it unless you're gonna order other stuff too.

Burns Stainless has mild and stainless steel bungs. $14.00 for the stainless and something like $8 for the mild steel I think. http://www.burnsstainless.com

 

i know where to buy them im just asking if i NEED to put another bung in the pipe or can i just take out my secondary o2 and put the wideband in there?

I wondered this question as well before I got the car tuned. Especially since I have a test pipe and no secondary O2 bung.

Thankfully the wideband plugs into the primary O2 bung. You unhook the stock O2 sensor and plug in the new one. The ECU reads off it while you are tuning and making adjustments, once you are done plug your stock O2 sensor back in and your good to go. There might be different wideband setups, but this is how the FJO works with hondata.

 

if choose to use the AEM Uego, you can run your factory ECU AND wideband outputs off of the one/single sensor.


below from the AEM site...


AEM Wideband UEGO Controller

AEM's Wideband UEGO Controller is available in single- and dual-channel modes, and is the most affordable UEGO controller available. The AEM Wideband UEGO controller has a very low current draw, and features both 0-5v calibrated output and 0-1v calibrated output to mimic the factory narrow-band sensor, eliminating the chance of a factory computer issuing a trouble code.

Key Features:


Ideal for use with ANY aftermarket standalone engine managament system


Accurate to 0.1 AFR (Bosch UEGO conditioning)


Available in single- or dual-channel modes


Bosch sensor(s) included


0-5v calibrated output with 0-1v secondary output to eliminate trouble codes


Extruded enclosure features titanium anodizing for enhanced durability

 

AEM is just starting to look better then Hondata. Better Graphs and all in my opinion.

Seems the AEM has quite a few worthy benefits ...
Jack, looks like I may be down to have you use your dyno skills one of these years.
