    I've been quietly studying up for this project for many months. It seems the technology wasn't quite ready, but is starting to catch up real fast.

    PS It would sure be nice if injectors were rated in "gallons per hour" or "liters per hour" instead of pounds. This means you need to estimate the volume of fuel flow by using the known density of...

    MPG can be calculated using speedometer and fuel used info. It is more reliable to use injector "on" timing than the amount of fuel remaining in the gas tank. That's because the tank float mechanism...

    Well, most people look for what's easiest and don't think about things like what will last and what won't. MDF is great because it is cheap and it is dimensionally stable, meaning it won't tend to...

    Wow! You were serious! :) Is that MDF you're using to make your dash? It's not suitable for outdoor use. It needs to be sealed with water-thin epoxy to turn it into a composite. Otherwise it will...

    If your car is General Motors, the ECM makes "injector on time" available over the serial data line. If you can somehow tap into this and read it, you can calculate fuel used. I don't know for sure,...

    I think that is the right idea. As time goes forward, it will be easier to create a PC-based, dedicated system that can operate full time, be reliable, and turn on almost instantly. This aspect of...

    More good points. But I can't use large screens, though, so that is just not an option for me. I drive a big car, but my dash is not that big! ;)
