Here is a shot of the LCD dash that has been a long coming addition to my bike. It is an 8 inch sunlight viewable LCD from a ATM. You can tap any gauge and replace it with another guage from a list of monitered inputs.Tap the screen a couple times and it will go to a tuning page where all the tuning can be done. I still need to finish a convertor for a speedometer-odo and maybe a thermocouple input for EGT. Jim

I wont ask where you 'found' it, & what about a gear-position indicator, I recall that Suzuki were proud to have those in the dash panel back in the `70s.
10:1 mixture? what fuel?

I doubt that I will do a gear indicator on a 4 speed but it could be handy with a few more gears.

It is just gasoline. The engine is not running in the picture so the fuel mixture is reading the default value. It is set up to read from
10 to 20 to 1.

The panel runs on a mini ITX industrial motherboard with a full windows installation with GPS. You could even watch U-tube videos on it. :o

Jim, could we use it for tuning purposes or is only for you FI system?

It interfaces with my fuel injection system. Jim
 
I have a TrailTech electronic speedo. It has a digital display and can be calibrated to a high degree of accuracy. Considering the hit from a ticket can be considerable what with insurance premiums, I find it's a reassuring alternative to the Smiths sitting right next to it that does the wave. It's the only gauge I prefer in digital.

Is a simple garden variety broadband oxygen sensor worth it as a permanent fixture for a street bike?

Wow, If I had one of those I would never again have to fool with my iPhone while riding in the constant battle to determine the barometric pressure! :)

Sorry, couldn't resist. Mighty neat, Jim.
 
That's about the coolest thing I have seen on a Commando. I was thinking of running the AEM WiFi lamba probe setup I have on the Commando. It has an 02 input and a couple of EGTs and broadcasts to your iPhone. It's neat, but that setup you have there is way beyond! I have to see this bike sometime!

A wideband o2 sensor is nice to use for tuning a carb but I wouldn't leave it in place unless you were using it for feedback tuning with EFI. They tend to be high maintenance items.

It needs to be in a bung in the headpipe a few inches in front of the muffler. If you install it in the muffler or toward the end of the headpipe it will give inaccurate readings from the ambient air that gets drawn back into the muffler. That will make it show leaner than it really is.
If you are using a pickup that sticks in the end of the muffler it needs to have a tube long enough to get well into the headpipe or it will not be accurate. Jim
 
Jim,

Do you have any pictures of how/where you mounted the Wide 02 bungs? And what orientation to level (i.e. the ground) did you choose? I ask as I have been noodling around with a home grown data logger system and would like to collect AFR info from both cylinders. I tried the pipe up the muffler trick, but that didn't result in very good readings esp at low throttle due to reversion effects.

Thanks, David

The bungs I have used were right below the footpeg plate, just about in line with the rear frame tube. Pointed inward. The sensor must be mounted in the top 1/2 of the tubing to prevent any liquid water from going into it. Just a drop or two will kill the sensor instantly.

They will also work in the downtube between the first and second bend. They will need a heat sink mounted to them or they will overheat that close to the port. They can not angle downward or they will collect water after shutdown.

I use a 3 ft flexible pipe up the muffler when the bike is on the dyno. I use a small pump to pull the air up the tube and past the sensor. It works very well that way. Jim
 
There are a couple of Android apps like that now as well, msDroid and MSlogger and lots of serial - Bluetooth adapters available around the place
