Default ECM to PCM?
Firstly, I tried the 'search' function, but nothing directly related showed up.

I have a '93 LT1 Corvette with ECM, I would like to upgrade it to use a 94+ PCM system like my 94 Firebird.
Is it possible without having to completely rewire the car?.
Reason: I have all the tuning equipment for PCM flashing, and I don't want to get into the expense of eraser's and all that goes into burning a chip.

Any help would be appreciated.

Thanks
Sara Lou

You need to get a new harness, idle air control o2 sensors and the like. It is pretty simple
