got it from http://www.machv.com/wio2sekit.html Great company, fast shipping. The one they show is just a digital readout, which is what I got, but it also has an output wire to go to a data logger and a wire that you can splice into the ecu if you don't want to add a bung for the sensor. You can replace the factory narrowband sensor with the wideband one, then run this wire to the ecu instead of the original narrowband. I already had an extra bung, so I set it up stand-alone. The company's website also shows some new models with wireless datalogging ability.

nice........here is my AEM wideband

 

now the question is, what the heck am I looking for on it???? Its really only relevant at full throttle, correct, since its around 14.7:1 the rest of the time?

 

this is something i feel i need to get ...... (after being here a few days)

i need to get the factory SM downloaded, to start finding the location of these oem setups....

so the oem narrowband can jus be swapped out??

 

yes 14.7:1 is perfect burn with no load such as freeway driving, idle etc. Emission freindly........ Under load it should start to read correctly.

 

where's the ideal location for the sensor???

((alot to learn))

 

COMPTECH put my A/F sensor in the middle of my Testpipe.........

 

sheesh .......

i apologize here fluidz, but i wasnt aware you had the testpipes.....

these are in leu of the cats??... i have seen some on auction that seem to have fitments for sensors of some type....


how's the exhaust smell though??

 

My sensor is at the top part of my cat, inbetween the 2 factory sensors. If I was to replace a stock sensor with the wideband, I would use the one on the exhaust manifold. My factory cats are hollow and there is no bad smell.

 

Your sig stays stillen SC. Do you have that installed? Running stioch with FI is kinda wild. You shouldn't be that lean.

14.7 is 'ideal' stioch for gasoline to burn, and your ECU will try to adjust to make that happen (closed loop). Under WOT, the ECU will go open loop and go on pre-programmed values. Thats where normally on a N/A car you want to see if your mods are causing the car to run rich or lean.

Is that the A/F you were tuned to, or is your stillen install a pure bolt-on?

 

stillen is a pure bolt on. I'm gonna have technosquare fix the fuel issues as soon as I have a wideband dyno done. the 14.7 is at idle and light throttle. It drops down a bit after that, but still a little lean for my liking.

about 13.5 at 2000 rpm to 12.5 at redline, under WOT.

 

that is pretty lean, mike. i would shoot for just under 12 while driving on the road. this will be a lot lower on a dyno, (unless your dyno is load bearing).

btw, which o2 sensor are you using? is it a bosch? if so, what are the last 4 digits of the part number..? 6066, 7057, etc...

 

FluidZ: Can you still open the Nav door with those gauges like that? If so, what does it look like when opened?

 

dont have any nav there, came as a empty hole, if you open it you see wires, but i would never open it because there is nothing there and it useless space unless you want to put some change and a garage door opener in there so they can clank around...LOL...........

 

Did you have to get rid of the ur pulleys because of the vortech charger only runs with stock pulleys , or because they take away from performance? what headers do you run thanks fluidz.

 

Yes i took off my UR pulleys because it would decrease the boost thus less performance, i do not have headers, stock exhaust manifold into Helix test pipes into Borla Dual Exhaust.

 

2003Z.....hows the blower workin? You must love the torque curve.........

 

Skidazzle, its a Bosch LSU4-2, dont know about the part numbers though, as I am out of town at the moment.

Fluidz, I absolutley love the torque curve!

 

Nice choice, that's the same one that I have.

 

The LSU4.2 is the 7057 sensor. Same that you can get for the Techedge Wideband O2. Nice thing about that sensor is you can pick it up at any VW/Audi dealership for under $40.

Which model did you get? M-200/M-250/M-300/M-400/M-500?
