I think the version of mailman was upgraded, and at least one person has
written that they got switched from digest to direct.  If you need to

Put your email address into the very last field, where the button says
"unsubscribe or edit options".

You may need your password...  you do have it written down in a safe
place, right?  If not the lists send them out monthly so you should be
able to dig through your trash and find it...  you don't ever empty your
trash folder, do you?  Or the list server will email you a new password.

A couple of users who tried their passwords have reported they don't

re-installed.  If you need to change your account options you'll have to
use the "mail me my password" button.  You can get there, for each list,

One of the first things we (Tech Edge) did when we decided the L1H1 
was way overpriced was to connect the LSU up in much the same DIY-WB 
circuit as the NTK. Sure, we got it to work, and it gave some sort of 
readings that we could have worked out a new Vout Vs. AFR table for. 
But I couldn't see the point of people spending time and money 
building something that was going to give just an "indication of AFR" 
- I mean, that's just what a zero-extra-cost narrowband sensor will do 
for you - or, for a little more accuracy, a fairly expensive NTK 
sensor and an inexpensive DIY-WB circuit.

At the time the NTK sensor jumped in price, I decided Tech Edge had 
come to a junction, so I asked the question : do we drop DIY-WB, or 
make AFR sensing a "proper" business? So, finding some local people 
who had a similar interest, I put a lot of development dollars into 
producing a professional quality microprocessor controlled WB unit 
primarily for the LSU. And shortly after we released that unit, we 
made it available as a DIY kit. We have sold thousands of these 
version 2A0 kits (as kits, and many more as "prebuilt" units). I have 
published the schematics for the 2A0 design, (but we retain the 
unpublished firmware) and it is a very popular device. But ...

It's important to realise that the Bosch LSU is designed to be 
different to the Honda-NTK UEGO device. It really needs to be 
controlled better to give similar results to the NTK. But, if it's 
controlled properly, it has the potential to be more accurate than the 
NTK.

In early 2003 I was in contact with the "Greek guy" (Giannoulis 
Kafetzis) that did this, and provided him with a little information to 
get him going. I can provide an email address if it's not readily 
available in the archives.

Sure, if you can get a junkyard part for a few tens of dollars, but if 
we're talking around the $100 mark then I can't see that the 
cost/benefit ratio is good. I'd stick with the NB sensor or go with a 
field proven low cost design with a low cost sensor. But if you want 
to go NTK ...

I'd suggest that Steve Nichols (see previous email from Jurgen) is the 
person to get the sensor from if you really want to use the "old" 
circuit. I believe he sells them for US$120. (we sell a connector kit 
for AU$9 that mates to it).

Final point: I'm not writing this in order to drum up sales, but to 
provide an alternative view point on the cost benefit ratio of the 
original DIY-WB design.

And, to those who, after all these years, think I did something wrong 
in making the original OZ-DIY-WB design readily available, and at a 
small cost - please don't put that forward as an argument to otherwise 
unbiased people who couldn't give a damn, and are just after honest 
accurate advice on how to get a low cost WB instrument.


Peter.

PS. I don't intend to get into any discussions that are otherwise 
ancient history, but I will respond to technical questions about using 
the LSU sensor.

Message-ID: <003101c52c48$124f9500$19c474ce@amdgeni>

anybody running this sensor?
it's NTK sensor with bosh 7057 type connector.
Like Jurgen mentioned already seems like it has different CAL resistor
than L1H1 mine measured at about 1k and I also mesured many other ones but they all less than 1k ohm.
Jurgen mentioned I have to dived by 10 but that make CAL value too small
because L1H1 sensor CAL seems too be a lot higher than that.
well I am getting confused. and it's really hard to find any information on this sensor.
what's the worst case can happen if I put wrong CAL resistor?
reading gona be way off?

any info would be appreciated..

thanks
Ivan

Hey, guys.

I recently spoke to Steve Nichols in Kentucky.  He bought a very large
quantity of NTK L2H2 sensors.  He offers the sensor for $120.  It has
the
Bosch connector, instead of NTK.  Also, the cal resistor is 10x the
resistor
found in the NTK L1H1.  You need to measure the cal resistor, divide by
10,
and replace with a substitute.

NTK sensors have been well over $150 for quite some time, so this is a
great
price.

Here's Steve's contact info: Stevenich at insightbb.com
Steve's web site is http://www.aussieimportsllc.com/

Best regards,
Jurgen

If you can wait a week or so, I should have artwork available so that 
you can burn a board or have one burnt. Once it is available, I will 
post it.
