Java program
So I got it all hooked up last night. I recind what I said about the Vss not being on the ECU; it is there on my toyota and it made things really easy to wire up.
I got really good signals into both left and right channels. There is a "drive to work" image of the signals attached below. Injectors on top (using the zener) and Vss in the botom of the image (using the opposing diodes the OP used).
What I could not figure out were the "injThreshold" and "vssThreshold". What is meant by "value above the noise"? And why are some of the values negative? If you look at my image from CoolEdit, none of the samples are negative on an 8-bit recording.
The gage said I was always using .0055 gallons of gas at every instant, whether the car was running or not. The miles were working, I think, but they were not quite right; I'll have to mess with the fudge factor.
I'll make the attached file in just a minute....
