Good Scan Tool?

Looking to buy a good Scan tool. Main vehicle will be my Taco, and the wifes Suzuki. I want a scan tool that can read everything... not one of these "code readers". Need to know what the O2 sensor levels are, open loop/closed loop, inlet air temp, detonation counts, MPG's... etc. I want the real deal computer. Opinions on a particular one?

 

ScanGuage II is the general tool for Tacomas that everyone uses

 

Scangauge II does everything you are looking for.

 

So it'll do TPS value, Air temps, Detonation counts... all the good stuff right? What does it do for ABS/Transmission/Airbag? Will it work on all OBDII Cars?

 

just go to scangauge.com and read up and see if it fits your needs, if not, then do some more research. FYI, the SG doesn't do the tranny temps yet, not sure about the detonation counts.
