I have a race car. Two cylinders, magneto fired, approximately 14,000 volts (measured) to the spark plugs, runs about 8,200 rpm. My current engine is one spark per fire (max 4,100 sparks per minute per plug), but the next engine, soon, has a wasted spark, so fires both plugs at about 8,200 rpm.
Will this cute, sexy little creature allow me to detect misfires? As in, the cylinder doesn’t fire every time. Or fires with reduced/increased voltage. I’m thinking “noise” in addition to the waveform. My professional advisor says that I would be shocked at how often my engine misfires.
I also hope to set the spark plug gap with it. Record the waveforms at the recommended gap, then start opening up the gap until misfires start. The back off, narrow the gap some.
Heavens, at this size, I could duct tape it to my frame and record an entire (60 second) run!
If it will do this, would I need to buy anything else? How would I attach this to the spark plug wire? I be a engineer, and have a complex data acquisition system that measures practically everything in the car but my heart rate, but I haven’t played with an oscilloscope for decades.
Oh, and it would be worth the price just to have fellow drivers walk up to me and ask what I’m doing. “Oh, just using my oscilloscope to check the plugs, fuel, battery, wires, and such.” (no, I don’t expect to be able to test all of these. . . ) “THAT’s an oscilloscope???” “Eh, get with the times, man! What, are you still living in 2010?” “How much was it?” “Oh, well, if you have to ask. . .”
