Duty Cycle Oscilloscope Test Question
Hi guys, I was trying to set the mixture on my 1980 Porsche 911 SC using an oscilloscope. I'm getting a big dip on the graph. Please see the attached photo. Any idea what this could mean? It's my first time using this tool so I'm not familiar with what all the numbers mean. Any help would be greatly appreciated. Thanks!

Oh really? All the photos I've seen show squared off graphs.

Let me ask an obvious, where did you attach the probes?
An O2 sensor cannot generate Vmax of 9.32V, or switch at 73 times per second. |
