Correct, heartbeat search and all that. But with ign and acc key switching then chatter could be starting again from the BCM.

I will do a video to make sure what I am saying is correct
This was the issue I was having for ages! It would find the PCM but not collect bytes. Was driving me insane I was about to convert to a Vt PCM. I've made 3 bin grabs so I will try clone a PCM tonight at work and make a small video of the sequence.
I've always tryed to do a get bin on reds, and when it would fail it would lock the PCM up until I removed the fuse in engine bay.
Have not had one lock up since doing it this way.
What sort of laptop are you using? Reasonable specs? It sounds like its not getting packets out on the ALDL bus in time and you are having data corruption. Even TunerPro is not happy as it ID the PCM as an Ostrich
The way you are connecting is stopping lots of chatter but is pretty risky for a write.
So I have just tried to write to the clone PCM it will erase and burn to all 3 banks but when it comes to validating the checksum it does the no response thing and no amount of key on or off will fix it.
I can read the bin back every time after so it's not bricking the PCM.
I have made a video of both trying to get a bin (of clone PCM) and a write. I just need to upload to YouTube when I get home from work.
My laptop is a dell latitude. It's not shy on specs. My old Sony viao used to connect fine to other vxs with the old cable.
This laptop and a new cable has not been able to. I tryed the vaio again with v151 and this cable and same as the dell on this car.
It's either the car has something funny going on with it or perhaps the cable is a big dodgy?
as a last resort I may try and delete the drivers and reinstall them for the cable.
I wish I didn't sell the last car with my nvram and cable!
