Petrol fuel injection, observed on oscilloscope

Examining petrol fuel injection on a Volkswagen Polo 1 litre engine, using an oscilloscope. We use a magnetic pick-up around one of the wires going to the injector. This senses the magnetic field around the wire, and so this will give us an indication of how much current is being consumed by the injector. This is the blue channel.
The other probe is an acupuncture probe and this measures the voltage on the line. This is the red channnel.
