TC55DA hour meter finally done right.

Same with the TC40DA's. Straight clock time regardless of the RPM.

Thats weird. I will have to take another look at my manual for the tc33d. I was sure it went by clock time.

My manual covers the 25, 29 and 33. All go by clock time.

I don't mean to offend anyone, but whether it's clock or 1830 rpm time, the difference is irrelevant. Plus or minus a few hours on an oil change isn't going to make a difference in either cost of oil or wear on the engine.
