Here is something you might want to take a peak at:
http://www.obddiagnostics.com
They make a nice little OBD-II diagnostic unit (with free software) that I personally use to diagnose cars. Its only about $80.00 and works great! (It IS serial though
)
Your altima is definately OBD-II compliant. All cars 1996 and newer are required by law to be OBD-II compliant.
From a feature standpoint, the included software will give you features like RPM, speed, throttle position, engine load, etc. Even tells you about your trouble codes, and what they mean (If your check engine light is on). You can even reset the computer's codes if it throws an intermittent one (sometimes useful). The software's OBD-II codes are fully documented, and will give you a plain english explaination of the code (like "code PXXX - Mass Airflow sensor output lower than expected" or "PXXX - Cylinder 4 misfire" and similar). The beauty of it is, the softweare will allow you to see WHEN and under what conditions the code was set (throttle position, engine speed, engine load, vehicle speed, etc).
Their software updates frequently, is free for download, uses very little CPU, and can record logs and play them back at later times. The length/time of these logs is dependent on available hard drive space.
The software is relatively "touch-screen friendly". It does not really require a keyboard or mouse, but a mouse would be helpful.
enjoy!
