First thing you need to do is have somebody flash the computer you put in your car with your car's VIN, and the correct calibrations for your car. Then, worry about your Hypertech programmer. It still may not work then. Hypertech used to work if the vin in the PCM matches what it stored from when your battery went dead. Seems like they use the PCM's internal I.D. number now? Too many weasels trying to program more than one vehicle with the same programmer, by putting the same vin in each. I may be mistaken, if so the corect vin in your "new" PCM may get you going. Or, the programmer may now be a door stop.

Looks like you bricked the ECM. This happens when a failure occurs during flashing the ECM. The ECM can be repaired but requires the chips be removed and flashed separately. Then placed back on the board and flashed again with the factory calibration. Ive fixed a few bricked ecms like this.

Your hypertech programmer is vin locked. There is a possibility of repairing your ECM and coding the vin to match so that you could possibly unlock the programmer. But I haven't seen this done before. There was a person unlocking older hypertech programmers but I'm not sure if they do it any longer.

I have a programer for 94-95 LT1. I don't use it any longer as the keypad has missed up. Its unlocked and ready to go if your interested. All you would have to do is place your working keypad on it.
