can some one recommend a decent odb2?
 

maybe something that turns off when you turn off the car...i looked up Edge brand but its too expensive, if i can't find something better i think this one maybe ok:

Amazon.com: BlueDriver - Bluetooth Professional OBDII Scan Tool for iPhone®, iPad®, Android: Automotive

PLX Kiwi OBDII reader

They have a Wi-Fi and Bluetooth version for code checks and live gauges.

Is it real time or is it delayed slightly?

I use an Automatic:

It has a good app and works with LapTimer as well.

Faster refresh rates and increased number of simultaneous data signals cost more $$$.

I use the OBDLinkLX and love it. Secure, fast and no battery drain

If you just want to scan codes, the PLX Kiwi will do the job, but for any of the cool real-time monitoring possible with Torque or similar apps, OBDLink is the only way to go. i was able to pick my OBDLinkMX or $125 a year ago and it's down to $90 now on Amazon.

thanks guys i bought odblink mx :tiphat:

if one's just reading and clearing codes, just get a basic one. no need for bt fancy.

i have actron from like 15yrs ago. works fine.

dat said, my z's nuvi has ecoroute (was it?) hooked up for real-time gauges (wirelessly ofcourse). :p

i dont want basic, i need fancy
