OBD-II Scan Tools

All,

I am in the processing of researching diagnostic scan tools for my '99 Infiniti I-30t. I've pretty much settled down to two makes: AutoTap and AutoXray. Just wondering if anybody out there has either of these two products and would like to share comments on them. Comments on other tools, are also appreciated.

As for why I am purchasing a scan tool:
-As an engineer, I'd like to learn more about cars
-Analyze performance
-Self-Diagnose and attempt to repair simple problems.

What I'm looking for in the tool:
-OBD-II generic parameters
-possibly CAN protocol compatibility (need to look into this more)
-Retrieve data and plot results on computer
-Price range: $200-$400
-Upgrade compatibility

Thanks!

autoxray is a waste of money.. They have no respect for existing customers and want too much money for upgrades.

try auterra (www.auterraweb.com)

needs a palm M100 or better (now supported on others)

version 4.0 and up has dynoscan stuff

new version 5.0 supports CAN

I find mine is just as good and makes neater gui than the snapon modis....and costs about $7500 less

Look at our stuff www.autoenginuity.com. We have a lot more support and features then AutoTap. I think you'll find we are far superior.

This is all you need I've used it a couple of time and its good as new. It also includes the palmpad and the extra cable u need:
