What do you do with this thing?

Yea if you have a reader you can get all kinds of shit

Misfires (which cylinder and # of misfires)

Fuel trim

Idle air temp

Coolant temp
Can't remember what else. Only had one 96+ and that was a while ago.

This. $80 investment. $100 if you want it to decipher the code for you on the screen (though, the smartphones are useful for that, too)

>not buying the chink 5 shekels ones who do the same

If you don't know what you're doing you're wasting your money

If you do know what you're doing it's a wonderful tool

John Q. Public with his $80 handheld reader can spend an afternoon scratching his head cause he doesn't know what to do with a misfire code and no additional diagnostics

A tech with something like CONSULT II/III/III+ can do just about anything


You get out what you put in

>Other than just scanning codes and watching dials...is there anyway to pull real diagnostic data out of this?

YES. Check this this recent past /o/ thread for info about real time data displays of your car's data. There's no need to buy expensive standalone test equipment unless your car's instrumentation is faulty.

Bluetooth communicates with android apps in either a tablet (nice bigger display) or smartphones.

Would help if I posted the URL which is good as of now. No telling how long 4chan keeps them around.

My car comes with a coolant temperature gauge that resolutely stays centred and 'normal' until long after it's reached a water temperature where the chamber seals will start to cook.

It's absolutely a helpful thing to have because it shows the actual coolant temperature rather than a lie.

LTFT is a good indicator of problems with the engine that the ECU is tuning out. Subtle shit like air leaks, or possible shit compression.

Cat temps over 1400C are signs that omething amusing is happening. If the rooster tail of sparks out both pipes weren't the same....
