Bench programming a LT1 PCM ?

[brian89gp]

How long does a flash through the ALDL take?

Exactly? But not that long, just a couple minutes?

i can only speak for the 93-95 3100 PCM using the madtuner package, but i seem to remember it taking ~30 seconds to setup and secure comms, then 60 seconds to flash each PROM.

i imagine 94-95 LT1 will be double that.

Old thread...new related questions: I finally located the blue and black connectors and set up the pins via the CATS Off Board Programming Diagram LT1 you supplied. I also looked at your programming bench picture and noticed that the PCM on your bench had a four (4) connectors plugged in. Just want to verify as I finish this LT1 bench flash harness that only the blue/black connectors are required?

Just need 2. I had the complete pigtail and did not want to strip it down. So I just plugged in all of them...

Thanks...I need to purchase the ALDL interface for the bench harness and PC - will either of these work for my 95 LT1 flash:
