KR> Cyberdyne mixture meter
I just ordered a stainless steel nut in the correct size from McMaster Carr, ground the correct radius on the bottom to match the exhaust pipe, and welded it on.

Hi Mark. Can you tell us about which exhaust bung you welded into the manifold? I'm wondering what size to order as I took the plunge like Chris...

There is a way to protect the element on an O2 sensor. When you make the bung, create a small hood to protect the element. Something like the bill of a ball cap. The hood is positioned on the upstream side of the exhaust flow. Make it about 40% of a circle and just long enough to cover the element. The sensor will read the exhaust flow just file and the combustion residue will not collect on the element. The O2 sensor will last many times longer with this small mod. Someone discovered this when running 60lbs. boost with 110 octane race gas. Interestingly, Chrysler cast this little shield in the exhaust manifolds of the later model I4 8V motors.

Thanks Brian, I decided to order the Intellimeter (Cyberdyne) meter as per the comments earlier.

I had one in my KR from Westach. It was a 2 1/4 analog meter and worked great. I like analog meters better than just LED. They normally stock a 2" round automotive gauge, but for just a few day wait I had them make me a 2 1/4 standard aircraft mounting type gauge. I also had them incorporate a mixture meter in one of their quad gauges with I think it was CHT, EGT, and I can't remember the other one. They are very good about making custom gauges for low cost if you call and ask.

So if you are only going to monitor one exhaust tube which cyl should that be? Or does it even matter?

Thanks Chris. I notice this meter recommends using a narrow band O2 sensor instead of the wide band type I was planning for. What O2 sensor are you planning to use?

This question was not directed at me, but I do have an opinion. An inexpensive ($20) narrow-band Bosch "one-wire" sensor will suffice just fine for this job. When this thing says "too rich", it really is, and when it says "too lean" (the bottom LED), you'll have already noticed a real power drop, so narrow band is fine. I like to keep mine at the point where the bottom LED is barely flashing on and off, or "just south" of that (not even visible). Wide band units and there sensors are very expensive, as was mentioned, and simply not needed for our application. I have almost 1400 hours flying behind one that looks just like this (apparently a Cyberdyne knockoff, or perhaps just "rebranded"), and I can't imagine what other information I would need from an air/fuel meter.

KR> Cyberdyne mixture meter
I am planning to install an O2 sensor and mixture meter as per Sid Woods presentation from a few years ago that I found on the KR net archives. Seems that the recommended Cyberdyne mixture meter ( 280-7009) has been discontinued? Not on JEGS web site or auto performance sites. Does anyone know where I might still buy one of these cheap analog type gauges in the USA. Most others I have seen are expensive ( $170 +) and use expensive O2 sensors. Any help appreciated.

Yep, I did what Mark suggests. I purchased the narrow band Bosch sensor from summit. It's $18.
