I have no 411/896 on hand, do have some 1Mb 03-07 truck ECUs though. Will download and poke at it, if it supports the later PCMs I'll be abl to offer prompt feedback.

Downloaded on my shop computer,unzipped but getting this error when I click on program.
I'm using Windows XP pro sp3,haven't tried on my laptop but didn't really plan to (win7 and have to use a serial convertor).

"The application failed to initialise properly 0x0000135". This means your machine does not have the microsoft .net framework on it. There is a link to the download it from microsoft in the software release thread on PCMHacking.net

I updated to V1.02 and just read a 2007 LS1b 1mb PCM. Works PERFECT. Thank you for the update and the SEED/KEY addition.

Okay,finally got a chance to try it out.
No issues on an 0411,a V6 pcm didn't unlock but did read cal/OS info iirc.
I did want to post up that this will not work using an AVT-838 though.
I got my AVT boxes mixed up,really wanted to keep my old serial box hooked up to my shop computer/bench harness.
But the old box wouldn't reset/initialize using this tool.
The new USB 85x box hooked right up and no issues though.

I still have a couple pcm's to run through,and i'll post up the info from them as well as the V6 pcm that didn't work.
(it's one of the bastard 98's)

I may have spoke too soon. I tried to open that bin in Tunercat and EFILive and HPTuners and it won't open---says it is corrupt. So, I read the same PCM out in Tunercat and saved it as .bin. Then I opened it in HexWorkshop and did a compare. The LS1Flash bin only went up to address 80000
