Bench programming a LT1 PCM ?

[RobertISaar]

i don't care much either way for flash vs MEMCAL.... takes less time to swap out a MEMCAL than to wait for the flash to program over the ALDL port.

the advantage of the PCM itself though, if you wanted the ultimate 6811 based PCM, these are on the very short list of potential winners. all of the dual 6811 units i know of:

93-95 northstar (dual 64KB BINs in a MEMCAL)
93-95 3100/3.4 RWD (dual 32KB BINs in flash)
94-95 LT1 (dual 64KB BINs in flash)
96-99 northstar (dual 96KB BINs in flash, IIRC)
96-97 LT1 (dual 96KB BINs in flash, IIRC)

i THINK those are all of them.

How long does a flash through the ALDL take?

[EagleMark]

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

[RobertISaar]

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:
