The Durametric tool will provide the following information;
Operating Hours Counter: 459
Ignitions Range 1: 9768/459h
Ignitions Range 2: 12/418h
This means that the engine has been operated a total of 459 hours.
The engine hit the rev-limiter for 9,768 ignitions, the last time being at 459 hours. So this indicates the engine was red-lined and the last time occurred very recently (within the last hour of operation) since the engine only has 459 hours.
This engine also exceeded the redline for 12 ignitions at the 418th hour of operation.
Each "ignition" is defined as a single spark plug firing event so there will be 6 ignitions per crankshaft revolution. At high RPM (redline and above), it is easy to get a lot of them even if the redline or over-rev was only momentary.
