I've wanted to make a little toy for quite some time now, but I'm having trouble locating information on my car.
I've got a 1991 Toyota Corolla. I would like to make an interface that can read from the ECU to get current speed and fuel consumption so that I can display an instant view of current fuel economy.
I know some of the newer corolla's have this feature, as do thousands of other cars, but I'm not sure if this model year had that option.
In the end, I would like to create a small screen that displays the current MPG I'm attaining, and perhaps an average.
Any help would be appreciated, thanks in advance.
