I'm absolutely going to try to switch to a single carb in the spring. I did talk to the local motorcycle mechanic, and he said he'd do the conversion for $250, not including parts. I can't imagine spending over $500 just to make the switch to EFI. But it would definitely be cool to have.Conversion to a good single carb would be fine unless you had the electronics Jason does.
I assure you I still take great pleasure in riding! Now I am able to measure exactly how much fun I'm having per ride! 😂😂😂Jason, have you ever ridden your Vulcan for, you know, fun? Or leisure? You're like the Mad Frankenstein of Kawasaki Vulcans! 🤣😂🤣
Market this gadget to Kawasaki, The Good Times Meter!I assure you I still take great pleasure in riding! Now I am able to measure exactly how much fun I'm having per ride! 😂😂😂
I was unable to ride for three weeks due to an appendectomy, so this kept me from going crazy.
I rode about 120 miles today. I added a total revs counter, because why not. It's currently only visible in the debug mode (text way too tiny to see while riding). But I'm just shy of 400,000 revolutions on the engine today. I also have Ambient temperature (shown in Fahrenheit) and a placeholder for Cylinder Head Temperature and Exhaust Gas Temperature (both were a request from the New Zealand fellow). GPS data is strong (VDOP, PDOP, HDOP, Sat etc). The whole trip consumed about 40% of the battery.

I love reading about your project! At the end of the day, what exactly is the ultimate goal here? Don't mistake this sincere question for anything other than that. As exciting as it is to see your progress, I'm still not quite sure what the goal is.I refined the calculated speed to better accommodate gear changes.
If the RPM changes by more than 12% within 1/2 second, it assumes a gear change and calculates the speed based on the expected new gear.
After 1/2 second, the GPS speed again matches the calculated speed.
This keeps the displayed speed from jumping around.
It's not perfect, and the graph will sometimes show small spikes in speed, but it's much better than before.
I added 2 resettable trip meters that track miles, engine revs and running time.
I might add a 3rd: one for oil change intervals, one for fuel ups, and one for a particular trip.
I'm working now on rotating the accelerometer data to accommodate non-level mounting.
Once this is done, it'll be possible to estimate speed by integrating acceleration over time.
GPS speed not only has the 1/2 second delay in reported speed, it also has a longer and somewhat variable delay in showing speed when accelerating from a stop.
As a result, the gear indicator isn't reliable until about 3rd gear on spirited accelerations.
Rotating the accelerometer data will also allow me to record lean angles.
Using acceleration data for speed would allow me to maintain speed should I lose GPS reception.
Eventually, I should be able to corelate changes in RPM to acceleration to determine speed and gear without GPS.
Somewhere along the way, my GPS stopped updating 10 times a second and is only updating 1 time a second.
It might have been when I told it to use multiple GPS networks (GLONASS, Beidou, Galileo etc).
Some GPS units lose reporting frequency when using multiple networks.
I put one thermocouple into a radiator tube while I was doing a coolant flush.
Unfortunately, the probe is in contact with the metal housing and it's shorting to ground.
So I'm not getting a proper temperature reading.
I put it in the hose between the thermostat housing and the fill cap from the cap side, but I couldn't get the probe to go past the lip.
I added a grade calculator that compares the altitude every 1/10 of a mile to determine the grade of the roadway.
I added lifetime max speed and min/max altitude.
I modified the physical power button to function as a physical sleep button (short press) and a soft power button (3 second hold) in addition to a hard power button (6 second hold).
This allows for power down with gloves on. Previously it required the touch screen to safely power off (save all variables to memory).
Waking up from sleep happens either by screen touch, or key on/kill switch off.
Sleep happens either by a short press of power button, or 2 minutes of inactivity (key off/kill switch on) and GPS speed under 3.5 MPH.
I just don't know when to quit!At the end of the day, what exactly is the ultimate goal here?
Agreed, for sure. But I had to know if there was some sort of ultimate goal he was after. Tinkering for tinker's sake is always a good thing in my book.To me it sounds like an engineer “engineering” for fun and I say why the hell not? If you’re selling a product then finding a practical purpose is always important, but If you simply love science and want to apply it to wherever possible then I say have at it. Keep asking more questions and finding more answers. More data is never a bad thing it may come in useful later.
That’s my GenX tech guy mind frame.
Nooo, no math error there. Your expertise and skill are impeccably perfect, Jason.I decided to take a crack at an MPG and fuel consumption estimator. According to my screen, I'm getting -18.5 MPG and I had 0.4 gallons more in my tank after my commute then when I left!
Clearly a math error somewhere.
