Lambda and engine tuning in data
I thought folks might like to see this after I posted it on FB. A couple graphs of the lambda curve from my 3 liter. I stopped trying to get it better when I realized the carbs I have don't flow enough air. I thought the motor was leaning out and laying down at the top, but it was really just running out of air. A set of ITBs, MaxxECU, and a few more upgrades will take care of it!
If you have a car with carbs, having a lambda (oxygen) sensor is a great tool to see how efficient your car runs!
The back straight at Watkins Glen in time-distance plots.
Scatter plots showing lambda vs. RPM colored by TPS. The histogram is a simple tool to see where in the range you are running the most.
