Thanks for the reply
Trying to flash a 96 Impala SS with 24x and repinned stock harness.
Pins at the Blue LS PCM connector were just verified by me today. All grounds good. 12v switch and constant good. Serial good continuity between ALDL and PCM.
The ALDL is verified to have power by plugging the V2 box and the V2 box comes to life, (not connected to laptop).
Am using Laptop with EFI Live Scan and Tune V8.2.2
I use the (activate licence) and (full flash) and each give me $0101
The laptop is connected to the V2 box and then the V2 to the ALDL.
This all works perfectly on my Silverado 2003.
The 2 PCMs I have tried are "new" from EFI Connection.
Is the "new" PCM required to have some sort of Factory flash before my EFI Live can flash it?
thanks,
Karl
