Misfire Detection Carbon Tracking

Misfire Detection Carbon Tracking


Detecting Ignition Misfires, Carbon Tracking…
As seen before, we used the Zapper Ignition
Tester to uncover, and make carbon tracking
ignition issue come to the surface. The game
is to stress the components, and see the spark
zapping.
In this extended explanation of ignition misfires
related to carbon tracking, we will use our
equipments of choice. We will use a combination
of the Zapper Ignition Tester and our Clamp-On
Ignition Probe. We will also show how to use
all this with the oscilloscope, and analyze
the signal quickly.
These tests are not a necessity, but are explained
here, to show you how our tools can be used.
If needed, you can always employ these techniques
with the oscilloscope. We start by using some
form of ignition wire, similar to the old
distributor high voltage wires. The ignition
probe goes right at this wire. It is a simple
hook up that will not take much time.
As you can see, the Zapper can be adjusted
to simulate up to 2000 RPM, and the dwell
can also be changed from 2 milliseconds to
one half a millisecond. That is 500 microseconds.
That is enough to stress the coils, and other
connected components to the maximum levels.
Seen here, you can see how the ignition waveform
changes as we increase the RPM. We can also
change the dwell or ignition coil pulse width.
With the Zapper, ignition probe and oscilloscope,
we can actually see what happens during a
carbon tracking misfire. The ignition waveform
may look slightly different, because we are
not using a real spark plug. We are using
the Zapper spark gapper, but it is very close.
Hope this sheds some light on the issue of
misfires and carbon tracking.

  1. Our third ZAPPER Ignition Tester video that deals with Scope waveforms and using the ZAPPER to acquire a signal, test, and flag carbon tracking misfires (most common). Here the ZAPPER.

  2. Hey Mandy,

    I'm a fan of your work. I was wondering if you could make a video someday of all internal parts (ex A/D Converter, CPU, RAM,ROM etc) of the logic modules used in today's car to familiarize all of us on what these chips look like and the reason they are there and what they are used for? This would be very helpful to all of us who want to learn deeper into the mystery of auto electronics modules.

    Thank you

  3. Sir your videos are incredible. I really appreciate your spending time to put this excellent material out. Thank you
