Best option for automotive scan tool?

[deziking]

What are some of the options I can get for an automotive scan tool. I am not talking about $100 where it reads code. I want to be able to get live data, for like the o2 sensor, I want to be able to open and close the purge solenoid for the evap from the computer. Is there any good deals where I can get one with laptop plug and play that supports all vehicles from audi to mercedes. Thanks for your time.

I use a Scangauge II. Had it for almost 5 years and love it. It scans for codes and gives you live data for all sensors installed on the car, if there is a PID for it. Customizable for trip data and such. And it works on any OBD II car, including VWs and M-Bs. Even Hyundai ;-)
It might even be able to open or close your purge solenoid, if you can find the programming codes, as it has the ability to run custom commands. There is a lot of info on the web, but quite often, specific stuff is hard to track down.
Goes for about $150, tho.

try looking at x431 diagun,or maxidas ds708,or autoboss. most of those will do every car and have alot of features you are looking for.They are not cheap about $1000 to start at the very least but are professional grade tools.

In all of my diagnostic tools, i enjoy the Launch X431 best. . It has accompanied with me more than 2 years! It could update online to keep space with new models, never outdate
All most of systems, it could enter and diangose!
I used it for key learning too! quite tool for me!
The only pity is that i have to purchase the new update after 1 year!
I got the update information from http://www.ecutool.com/Ten-Months-Up...agun_1994.html. I will try to update it for 2012 models!

Launch x431 or Diagun is the way to go.
I have a OTC genisys and it works ok for most stuff. Doesnt work well for european stuff other then VW. It also has a 4 channel scope.
