I know that all manufacturers are different, but don't some of them require that the engine be hooked up to a computer for warranty requirements?
Jeff and Julie-
I don't know if it's a warranty requirement, but it is nice and comforting to get a four page printout of your motor's use, performance, and self-monitoring.
You can't get this with your home computer, to my knowledge,
The newer motors with Electronic Fuel Injection have computers that are every bit as sophisticated as your new car.
Here are some of the things reported to you and your mechanic from the printout (from and earlier post):
A four page printout was generated between the motor's on-board computer and the shop's diagnostic unit. Just like your car, the motor's computer has continuous monitor/control/memory functions and reports in at service time to the shop's diagnostic unit. There are multiple sensors that sense atmospheric and throttle body intake pressure, throttle position, rpm, engine timing, fuel mixture, consumption rate, water intake and circulation temperatures, battery and voltage regulator performance, oil pressure, and more. The computer also logs all the time spent operating in the various rpm ranges, so that you can see how you're using the engine. There are diagnostic codes for any problems, just like your modern automobile/truck. The print out eliminates a lot of "wondering" about your engine's condition and how you're making use of it.
