I've been tinkering with OBD2 stuff again. I'm trying to come up with the "best" display for our bikes. There's not a whole lot of data exposed to us though. Here are the PIDs that the ECU reports as being supported:
A number of those things are good to know for tuning, but would be a lot more useful in a recorded log as opposed to just seeing the value on your dash as you ride around. Other than very specific test cases (probably after analyzing recorded data), they would probably just be neat to watch and nothing more. Speed and RPM are already shown on the dash. Depending on the precision and how quickly it updates, a digital tach might be of some use.
The big thing seems to be precise coolant temp, since the stock dash only has a few bars to show that. Intake temp could be handy too, even if it ends up being not much more than an ambient thermometer (I haven't actually looked at IATs while riding yet). Other than that, I'm not sure there's really much to add to a regular dashboard.
I really like the simple, clean look of this one. The downside is that it can only display one thing at a time. But if you basically only have one thing to show (e.g. coolant temp), then a single display is fine. If you don't have to switch between different views, that means you also don't have to add buttons and circuitry for the switching stuff, keeping the whole thing that much simpler.
If you want to show a few things, this is a pretty simple display.
So what are your thoughts? What values would you like to see? What type of display would you prefer? Do you want a screen that shows several values at a time, and you can page through every sensor available? Do you want one that's nothing more than a digital coolant temp gauge?
I'm not sure if I could ever get this to the point of being cheap and good/reliable enough to actually sell it as a product, but it's definitely an option if I get there. But I figured I'd at least get some input from others, to make sure I'm not overlooking something, and to see if it's even realistic to think about going down that path. I'm anal about stuff, so I'd have to make it perfect to actually turn it into a finished product that I would sell. Once I get it to the point where I'm happy with it for my own use, I'd be willing to work with people as a custom/DIY/tinkering sort of thing though, even if I never make to a full "finished product" that I'd want to put out on the market.
Code:
