    How do you flash a PCM for a 94-95 LT1 Y-Body?

    Howdy guys!

    I've got a 1994 Corvette who's PCM is hitting the dirt. I've shopped around but a lot of the LT1 PCM's I can get my hands on will need to be flashed for the Vette to run. I've looked around online but I'm not really certain of what I'll need to flash the new PCM, or how to best go about doing it so I don't muck it up.
    Does anyone have a particular software they use for flashing a PCM, or any certain tips/methods that work best for doing so, or a do's/don'ts for it? I really hope I can get her up and running again soon.

    Thanks!

    I use the LT1 Tuning Kit (software & hardware) from TunerCats: http://www.tunercat.com/cables/lt1kit.html

    $EEHack is a very good LT1 tuning option: http://fbodytech.com/eehack-2/

    Moates.net also offer a LT1 tuning option: http://support.moates.net/94-95-lt1-...bird-16188051/

    Once you get the hardware/software for this, how do you go about flashing the PCM with the bin file?
    I feel like it's probably something ridiculously simple, but I don't wanna muck around in something I'm unfamiliar with and brick my PCM the way I've bricked a few of my older laptops XD

    Simple yes, the flash (read / write) is through the Diagnostic Connector (ALDL Connector) in the vehicle. Load the .bin file into the software, then flash through the hardware connected to the Laptop / ALDL Cable.
