Durametric Findings

Need help deciphering
Information page reads:
Range 1 10,439/2123
Range 2 0/0h
Operating hours counter 2321.7

Does this mean the car has been redlined 10,439 times, the last time 2,123 hrs ago?
Never hit rev limiter?
2,321.7 hrs of use on engine?

Thanks,
David

Range 1 = ignitions at the rev limiter, range 2 = above rev limiter.

You've had 10,439 ignitions at the limiter (about 3,480 revolutions, or 30 seconds at redline) with the last occurring at 2123 operating hours (about 200 hours ago).

Is that bad? Doesn't seem bad for 18 years.

Not bad. There are 3 ignitions per revolution, so divide 10,439 by 3...that comes out to 3480 revolutions at redline.
Figure redline is 7200 revolutions per minute, or 3600 revolutions per 30 seconds, so 3480 revolutions at redline would be just under 30 seconds.
