My New Years resolution is getting my
 dyno working.
 I am getting together all the parts that I need.
 I have a running P-port RX8 engine for testing.

 One of the other things I need is a wide band mixture
 monitor.
 Rather than have just a digital read out I would like to
 record the data
 on a Hytek Automation 12 bit  8 channel data acq USB
 module which I have.
 I intend to try out several different EFI systems and
 eventually turbo compounding. This information is
essential
 for tuning the EFI systems.

 I ran across this Australian company on the net.
 Anybody have an experience with this company?

 What I like about this system is it's compatible with a
 data acquisition
 system.

 Here is the wide band problem in a nut shell. The Bosch
 wide band sensor puts a current out  ranging from a
 minus to a plus and I need a linear voltage out put in
the
 range of zero to 5 volts. This company sells the box that
 does the conversion and a digital display.  It is
 generated by a 12 bit Digital to Analog Converter using a
65
 word lookup table (with linear interpolation for improved
 resolution).

 Don't confuse this with some of the narrow band O2 sensor
 systems.

I built 2 of the analog versions and got them both
basically working. Still have 1 with the display. I never
got the data logging feature of it to work. TekEdge sent
instructions and the download for the logging firmware.
However the instructions were so complicated and convoluted
I couldn't get my analog mind around it. Since I had other
data logging I didn't continue with those updates. I don't
recommend their kit because the build instructions are full
of corrections and exceptions to corrections that could
become pitfalls.
I recently got an Innovate LM-1 which I think is a better
instrument altho it doesn't have any logging.

Thanks Robert for the heads up. I am not going to use their
RS232 data logging. I just monitor the voltage out. Was shipping from Australia a problem?
Are you interested in selling a unit that works?

You are welcome to borrow the TekEdge if you wish to try it out. It will probably need the firmware sorted out before its usable.

Robert

Great. Great. I would like to try it out I'll pay shipping.
Let me know how much.

Thanks.
