I just received my FJO wideband o2 sensor and I'd like to get some sort of a tail-pipe probe setup so that I don't have to get o2 bungs welded on every car that I tune.
I'm sure that some of you here must work with dyno shops that have widebands or must have your own, where can I get a good tailpipe probe that will stay put during road-driving?

I'd like something like what m&w has on their sites, but I can't find any info about where to get one:




thanks

where did you get the wideband and how much? I am in need of one.....

 

No where can you find a tail pipe sniffer that will stay in place for road testing. We bungee cord ours onto cars that are just rolling on the dyno and they almost fall out and off. Not to mention that the wires will be all over the place. You also will not be able to accurately measure the O2 content of your exhaust gasses with that type of setup. #1, there will be a long delay from the wiring to the processor and #2 a long delay from the headers to the exhaust tip, not to mention the exhaust gas will pass thru the cat converter and a muffler before it reaches the sniffer. We quit using our sniffer and use an O2 sensor directly connected to the ECU so datalogging is accurate. When we used our sniffer, the Lambda may be .08 at 5000 rpms, but really that reading was for 4000 rpms due to data transfer lag. You can't beat a lambda meter using an O2 sensor plugged in before the cat converter. Only problem is that we use ours for Hondata tuning and remove the stock O2 sensor.

 

wow thats a nice part rite there must have been expensive

 

Yup I agree.. using the sniffer that way is more trouble than what its worth.

We use our with a bung and prior to the Cat.. that is the only way to get an accurate reading.


HPilot: I have a few questions you may be able to help me with concerning using the WB with the Hondata.. we keep getting a CEL for some reason... mind if I shoot you an email? Thanks.

 

would any of you guys that tune hondatas be wiling to answer some questions on an AEM EMS setup?

 

What do you need to know?

 

thanks for the responses guys. So when you have a customer come in to your shop, you just take out their o2 sensor and thread your wideband in? Or weld on a new bung?
Seems like a lot of trouble . I may try out the tail-pipe thing anyways and see if i can get it to work. there's nothing vice grips can't handle eh

welding is pretty simple actually. no problem at all if you got the tools. if the o2 sensor is even off a lil bit you may get an inaccurate reading. thats the whole deal with smog legal headers... moving the O2 sensor from stock location.

 

We remove the stock sensor, and install our wideband sensor, no need to weld.
