Got it, posted it I thought but it's not showing up..

GMlan algo 0x96..

Had the seed wrong.. It's not the 2 bytes right after the key.. it's the next 2 bytes after that.. Once that was figured out it was fairly easy.. lol
I actually went thru the reversion test using the seeds but that failed so I tried searching with one of the keys and made a list of possible seeds, then started looking at hex files, bingo!!!

we just had the seed wrong..
works for 4 of the 4 files VX L67 Getrag has so I'm thinking it's good. Now to message my buddy and see if he still has a use for anything I can come up with, think he's already got it resolved though..

2012 Captiva 2.4L E37 SW 12647468 MANUAL ORI(Key=9CFE Seed is actually F9EF)
2008 Chev Cobalt manual 2.2L(key-7B11 seed is actually 54B1)
2008 Chevrolet HHR manual 2.2L(Key-8970 Seed is actually 377D)
2009 Chev Cobalt manual 2.2L(Key-86B2 Seed is actually 7725)


Gatecrasher, now it's your turn.. lmao.. either post up the file you have or send it to me, I wanna keep up the wins!!!

Hi all;

Are all of these Ecotec motors?
What year did they start using this controller? I know the Ecotec first came out in the Grand AM in 2002, since the 2001 I have has the 2.4L Twin Cam LD9 motor.
There are a number of these cars/motors in the local salvage yard near where I live that I may be able to get for next to nothing.

Not a problem, glad you tried to help.. your files are what got me to figure it out as I couldn't find a good one online.. I'd still be stuck so thanks!!

If you get the seedkey figured out could power pcm flasher be used to read and write these ecu's?

I have very serious doubts that the kernel written for the E38 and E67 ecu would work with the E37 ecu.. I do not have the knowledge of the internals but I doubt they are close enough to work, I think if they were it would have already been discussed at length..

I managed to find this picture of an E37 not sure how much help it is.
