Let's back up here and try to get some more information about what happened.

Which model of the flash scan are you using?
What is the software version of efilive on the laptop?
What is the version of software on the flashscan (Bootloader/FW)?

What model vehicle are we dealing with?
What PCM?
What OS?

What error messages are displayed when the EFILIVE software can not communicate with the PCM?

I am assuming you made a copy of the cars stock tune, then what did you do?

What exactly do you mean "The car is completely dead?"

Were you doing a full flash or just a cal write? Did you try disconnecting the battery for 15~20 mins?

EFI LIVE Tuning software 7.5.5
I'm using a V2 ver 2.05.19


Its an LS2GTO

I did a 'read calibration from PCM'

I'll go uplpug the battery now, I suppose it can't hurt.

When I turn the key on, the lights and radio turn on, but I get every error code possible on my dash, and nothing happens when I try to crank the car over.

sory for the short messages, but I'm pissed, because I'm supposed to be on my way to the dyno right now.

First point I'd look at is updating the firmware to the latest version, which would be...

Boot Block: 2_06_02
Firmware: 2_06_05

The latest versions are on the EFILive download Page

Another thing to look at is the ODB-II connection between the car and the V2 unit. Later model controllers can get very upset if the V2 has a bad connection. Resetting the ECM should help here.

If all you did was read the tune out, there should be little chance of causing a serious problem.

So you didn't flash the PCM, you only read it, and this all happened...?
