SawMill's "Load" scatter-plot. "Load," in this context, means grams of air pumped through the engine per revolution. Plotted against RPM, you get something that roughly approximates a torque curve. More accurately, it establishes an upper bound for how much torque the engine might potentially produce. At the left edge of the plot, funny things happen when the engine starts, stops, shifts, etc.

SawMill's "MAF" scatter plot. MAF is "Mass Air Flow," meaning how many grams of air the engine is pumping per second. Plotted against RPM you get something that roughly approximates a horsepower curve. More accurately, it establishes an upper bound for how much horsepower the engine might potentially produce.

SawMill's "VE" table. The cells are actually showing load, which is not exactly the same as VE because it doesn't normalize for temperature changes. I'll address that in a future version. The vertical axis is manifold pressure, the horizontal is RPM. Higher VE, made possible by intake or exhaust tract changes, or cam timing, is better.

SawMill's knock table (new in the 1.6 release). It took almost three weeks to gather the data shown. I suspect that most of the knock events happen during shifts, but can't say for sure. A future version will provide a way to answer that question.

There are dozens of parameters to choose from, the software allows monitoring several sets of six.

The download counter suggests that a couple dozen people are using this. I've heard back from three so far. Two have posted pictures.

All by itself, with no front-end software around it:

(The guy who posted this was justifiably annoyed with the fact that it had to be restarted manually after the computer hibernated and resumed. That was fixed in v1.4.0 though.)
