is that the 2500 unit? I'm sending this unit back and looking into another. The Mac needs cartridges, don't it?

I think code 12 was a default code, means nothing.

That's for code pulling. Scanners will show you 28 other live feed perameters for OBD 1 so you can see things like the voltage to MAP & 02 Sensors (no more guessing on what parts are causing problems). Also shows Left Bank/Right Bank info (perfect is 128) so you know if your running too rich or too lean on one side or the other. It worked good, for up to 140 seconds but crapped out.

Ya Mike, I knew you had a 5000 unit. I guess the only difference between the 5000 and 6000 is the 6000 has a couple more detailed info for OBDII. If i can find another 5000, should give me everything I want. My live monitor is what kept crapping out.

OBD2 uses engine ON and monitors live.

These units, as WW7 stated, do run live feed info-on many more perameters than just code related issues. For example, an 02 sensor might cause your car to run kinda crappy or slight miss, but not enough to set the code (02 should be running around 450 at cold idle and then live closed loop (warmed up) flunctuate between 300 and 500. One running at 350 cold and 200 hot might not set a code but cause the car to run crappy (numbers for example only).

That's what I thought. I was watching it change numbers as I was scrolling but before I could pull out of the driveway, it froze up.
I noticed that the numbers to the right (01, 02, 03 etc.) were blinking when on Live Monitor as you scrolled through, but then they quit blinking and froze back to the original start up scan. This is a fecked up unit then, right?
