Primary & Secondary Ignition
Bar Chart Display mode allows you to view the voltage levels of each cylinder in the firing order
on a single screen. Each cylinder’s primary voltage is displayed in Bar Chart format so it is easy
to spot a cylinder voltage that does not compare with the others. All cylinders are displayed in
the correct firing order at all times.
The Firing Volts Barchart displays a bar graph showing the primary voltage required for each
cylinder. Live, Min (Minimum), Max (Maximum), and Avg (Average) values for each cylinder are
displayed. The numeric units are displayed in volts. The cylinders are listed in firing order
sequence.
• The Live data value is the same data displayed in the barchart format.
• The Min value is the lowest voltage value recorded for that cylinder.
• The Max value is the highest voltage value recorded for that cylinder.
• The Avg value is the average voltage value recorded for that cylinder.
Pressing the Reset button resets the Min/Max/Avg data.
It is important to note that the peak Kv firing line will be different for each cylinder and will
change as the engine runs. This is because the fuel mixture for each cylinder is different and is
being adjusted as the engine runs.
You want to keep an eye on the Avg. data. The Avg. is going to show you the average for all of the
cylinders over time. If you see one that is significantly higher or lower than all of the others, this
indicates that is the bad cylinder.
