Ok, I have been reading up on this for this guy im getting ready to do a tune on his Cavalier with HPTuners. He doesnt have a wideband, I said he needs one for me to do it properly. The article is url=http://www.hptuners.com/forum/showthread.php?t=18320]HERE....
It states that you can hook a wideband up to the ac pressure sensor and log on the hptuner scanner to get afr. Sounds great, and I know it would work perfectly (at least it sounds like it). I dont know much about widebands though, i just hook em up to the guage. I dont have the pro interface either, so if this works i will hook mine up to it the same way.
1. A wideband puts out a 0 - 5v signal, correct?
2. Is it wired like a 4 wire narrow band? aka reference volt, ground, heater positive and heater negative.
3. Does it need its own 5 volt power source to supply the heaters, and\or just a ref signal? In other words do I need a 5v power for the sensing unit, and then a 12v power to the heaters. Please explain.
4. Will this work without a wideband controller? You know, just the sensor wired up manually w\o base controller.
5. He plans on using a bosch wideband that comes off a volkswagon? any suggestions on that or other vehicles with a year and engine size...

1. you need a wideband to tune properly.
2. wideband goes in the downpipe or exhaust.
3. you measure afr by using a wideband.
4. you need a wideband to tune properly.
5. whats done to the car?
6. you need a wideband to tune properly.
7. there is a VW sensor that is the same, and my friend is matching it up for me sometime this week. so he should have a part number soon.
I said its for my friends cavalier, i know i need a wideband to tune properly, and i did use a wideband on my car to tune it. Read the freakin reply. I really hate the sarcasm, since the only question of mine that you answered was #5. Dont be stupid. Dont even post at all. Your the kind of person that gives the org a bad rep...I did manage to find out my answers by asking a dyno shop owner though.
1. no, you need a module
2. no
3. supplied by module
4. no
5. The part number for the Bosch LSU 4.2 sensor is 17014 (usa part number).
Has anyone tried the JAW DIY Wideband controller? Seems like a good deal... i bought one to give it a shot. Its very similar to the WB02 original DIY kit.

Yeah, you cant just put an o2 sensor from a VW into the exhaust, and try to tune with it. The widebands need a "translator" so to speak, which is the controller module, that also controls the heater.
The sensor also depends on the wideband controller. That bosch number is good for innovate i believe, but wont work with AEM for example.
I have not used the JAW....but $45 for a wideband controller doesnt seem right....let us know how it goes....
the JAW is a good unit for the price, but theres alot more to screw up if you get the complete do it yourself kit. JAW has been discussed numerous times on the HPT boards and is actually very good unit. it does the same thing as every other wideband module out there but just doesnt look as pretty or cost so much.
you would be surprized how cloe you can get your AFR with a narrowband O2 if you know what your doing and if its a good sensor. when we dialed my car in originially we dialed in with a narrow band O2. once the wide band was put in place to confirm the AFR, it was found that the narrow band only put it off by like .1 or .2 AFR. we have since corrected that, but to me, for not having a WBO2, thats pretty close.

^^^^i dont like the sound of that....
My car was also originally dialed in on a narrowband on its first tune with a turbo. After I did that tune, I took and got it dyno'd and corrected it from there cuz he (the dyno owner) had the wideband. The narrow band was pretty close. I had it pretty rich in high rpms (close to 10.5 to 1) but i never had a lean condition. Of course, the car wasn't really run hard till it was on the dyno.

twas a brand new narrow band O2 sensor. most tuning shops recommend it gets replaced every 50,000mi i think. its a good thing to know that my narrow band was not far off from the wide band. car is currently dialed in to command 13.0:1 on WB02. on the dyno with the sniffer in the tail pipe it was reading 12.9-13.0:1... i was the only car there running its proper AFR though there were a few running pig rich on purpose.

haha. when i said you need a wideband... i meant he needs one. he should run one, and continue to run one. one you can leave in there and not have to ever take out. if you hate sarcasm then you will never like the org.
its pretty simple... to tune you need a wideband installed to tune properly. best bet is to go out and buy a complete kit and install it. options are lc-1, lm-1 is what i would recommend. there is also the aem uego and the plx something. but i would still recommend buying the innovate sensor. its what is recommended for it. and you dont have to guess if its gonna work.
I do like the org, just not some of the people that troll it... btw, iv been with the org for 3 years.
