Wideband Datalogging
 

Besides the Microtechs version, what other WB can be used to It's fullest capability? I know Innovative, for example, you cannot datalog on but you can use It for tuning. Is there another setup that can be used with the LT8 that the WB can be maximized with?

Well, you can datalog with the innovative WB, but that's using it's own software, and to make it useful would require a bit of extra wiring. I just went to look at the website/LM-1 manual and noted that it has a programmable analog output, IE it can emulate a narrow band O2 sensor. So, you can always wire the analog output of the LM-1 to your LT-8's O2 sensor input. Datalogging would just take place using the LT-8, and now the O2 sensor reading on the tables generated would be worth a damn :).

EDIT:

Again, looking over it, the analog output of the LM-1 doesn't look to be very useful. A nice sweep through the voltage range in relation to the A/F ratio would be nice, this looks like you set it up at only 2 points to display voltage...:(

If you search in this particular sub-forum, there was a thread about the TechEdge WBO2 unit, but the analog output was shit (lack of better terms, it functioned the in the same manner). I've still to find out if that issue had been addressed with the 2.0. :confused:

Joe, is there any end to your knowledge??!!

:o: As soon as that bull stops eating. :bigthumb:

Well, most of this is way over my head, but hopefully someone can enlighten us... would we be able to utilize this signal in the LT8? I'm assuming we'd have to use this "simulated voltage feature" (3 quarters of the way down on the next page).

Seems like this is a pretty good unit, but I would like one that I can connect directly to my LT8 to provide a real wideband signal. Obviously I would have to do my own datalogging since the LT8 doesn't do it, but I'm okay with that.

The LT-8 does datalog, just not any 5v WBO2 internally.

The LT-8 does feature a narrowband O2 sensor line which could be incorporated with a narrowband simulated signal from an aftermarket WBO2 unit. As far as your guess, you're right. I've looked at a different unit that only had 2 points of configuration as far as A/F ratio/voltage goes (innovative I want to say).

I've been hoping someone else would do this first before I go and make any more purchases, but seeing that I haven't seen anyone with that exact style setup as of yet (techedge 2/LT-8) I may just bite the bullet...I'd still like the use of a WB even without direct datalogging via the LT-8...

Well, the wideband area is just something I haven't spent anytime looking at, so have zero expertise on the subject.

But just from the little that I've read, it seems like the Techedge 2.0 unit is pretty good. And from the sounds of it, with the simulated voltage, it could be made to work w/ the LT8. I'm not sure how the price compares to other WB units, but it doesn't seem bad even for the pre-built unit. It seems like the AU price on the sensor is a little high -- so maybe with some searching around here for that 6066 sensor and a DIY kit, a person could have a full functional WB for a few hundred, and plug it into the LT8 to boot?...

I really have no idea how this price compares to others... or if there are even others worth looking at if they don't have a narrowband output...

Re: Wideband Datalogging
 

you could log a 1v input from a wideband that has a 1v narrowband output...just connect it to the black 02 wire
The new LT12/LT12S will be able to log from the Bosch LSU 4.0/4.2 sensor

I think this might be the route I take... w/ the TechEdge 2.0 I mean. The DIY kit is significantly cheaper than the pre-built kit, so I think it will be a good learning experience. Sounds like it will do the job nicely and for a reasonable amount of $$.

Anybody know a source for these Bosch O2 sensors?

Local parts stores don't carry them, and I can't figure out what the OEM application is. Anyone have this info?

I'm looking at the 6066 sensor.
Bosch number is 0 258 006 066. I've got a call into Bosch -- hopefully hear from them tomorrow. But until I know an OEM app, the dealerships won't do jack.

Well to add to the mystery or confusion, I did get a call back from Bosch, and they indicated that the sensor part # has been superceded by 16065 (instead of 16066 stock #).

Apparently this comes on Cadillac Cateras and some of the newer Saturns. And now that I look at WBO2.com again, they list this number too (0 258 006 065) as being the same sensor but with a different cable length. So there you go. :)

so hooking up a WB O2 to the LT8 will give you no benifit correct? it will still be read as a narrowband?

try this again, I typed this reply once yesterday and didn't go through...

Actually it should give you some benefit, but it has to be a 1v output WB. The LT8 only accepts a NB signal (1v) instead of a WB (5v). However, the WBO2 unit from TechEdge has a NBSim output that converts the 5v output to a 1v output (narrowband simulation). I have a feeling it's probably not as accurate as a "true" wb 5v output, but I think it's also better than just using a NB -- and probably the best you can do on an LT8.

I plan on using the splitter that TechEdge sells and running a true WB AFR for 'insurance' and the NBSim output to the LT8. I think then I'll "have my cake and eat it too," The cake just won't have frosting (true wideband). :)

I know this is slighy off topic, If i had a 5v wideband hooked up to a muiltmeter to display the volts, any ideas on how i can convert that to a/f ratio?
The reason i ask is someone offered the use of their W/B but i wouldnt really have a way to see the acutal readings besides a Mulitmeter

I would think you'd need to find the technical spec of the 02 sensor you're after...

here's a pic on the TechEdge website displaying the linear voltage of WB output -- but I'm not sure if you'd be able to read this right off of the o2 sensor -- I don't THINK it's quite that easy.

There is also this page on the techedge website, but again, I think these are the outputs from the TE device, not necessarily straight from the O2 sensor -- so not sure if this applies to all O2 sensors or not.

Got my TechEdge DIY in the mail yesterday. Will be awhile before it's assembled, but looks okay from what I can tell so far. :)

Be sure to let us know how the simulated 1v displayed on the LT-8 compares with the TE's display!

Not sure what exactly you guys are tryin to do and I don't have a microtech but my cousin is getting one this week so I thought I would chime in.
I bought the LM1 and have been using it in my 3rd gen for about a week now. (wow did the base maps suck!) I have just ordered the aux input so that I will be able to datalog rpm, map, iat, afr. The lm1 can datalog through it's own software, or you can set up it output to work for any voltage range between 0-5 v and for any afr values between ~9 and ~22. So from what you guys are saying....the microtech only has a narrow band input, in other word 0-1v. You could, for dataloging purposes in the microtech, set the lm! to put out 0 v and have that represent 10afr and tell it to put out 1v and have that represent 15afr. The microtech would then log the afrs assuming it was still a narrow band but with some simple conversions you would know the true afr. Thus making the numbers valuable. Do you guys agree? Would like to know so we can do this when my cousin gets his.

I have a Techedge v2.0 for my FC but it just hasn't made its way into the car yet (i.e. car needs to be put back together :D)
