The EIS uses a single, high resolution, 60-minus-2 tooth crank trigger wheel. This affords resolution unheard of in any other electronic ignition available today, offering spark accuracy of ¼ degree of crankshaft rotation. This accuracy means the system is ideal for the most demanding engine applications – that’s why it has set altitude and speed records.

In summary, your Electroair EIS delivers more power because:

• Spark timing is precisely controlled under all conditions, including rapid engine acceleration.
• Longer dwell time and a better flame front allow the engine to run better on lean and lean of peak mixture settings.
• Accurate spark timing allows sustained engine operation closer to peak power timing.
• 100% spark energy up to 9600 RPM on 6 cylinder and 12,000 RPM on 4 cylinder applications (at 12 volts).
• Long, 2000 microsecond (typical) spark duration (represents approximately 20 degrees)!
• Built-in timing computer
• No power draining magnetos to drive
• No moving parts to wear out or replace
• Built-in timing monitor lets you measure the advance with a voltmeter
• Options include: backup sensor, Tach output and remote timing control
