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.

Hi Paul;
I have one of the tech-edge DiY kits - it has not assembled itself since
I bought it quite a while back ;)
It was one of the recommended kits with megasquirt.
Note that it is RHOS - no lead.
Cheers

That is OK. I will test it with unleaded.

BTW do you know anybody making RX8 exhaust flanges? I am thinking of getting a batch made up.
