    Don't think I haven't tried. They won't release any information about their engine controllers. They said their hands were tied by the EPA.

    As for which bin, I disassembled both the 16245315 and
    09375577 binaries.

    I don't have either PCM, so I'm flying blind.
    So it's up to you guys as to which one you want to play with.

    Re: 68332 disassembler

    I am the one with the BDM setup.
    I dont know all too much about how to use it though.
    I have connected it and am able to read RAM and the flash. Cant write to the flash yet though.
    I am very interested in what was sugested earlier int his thread about finding the hardware addreses.
    Anyone who doesnt mind giving me a crash course and helping me with it (learning things yourself at the same time). Shoot me an email.

    can you pls email them or even better Magnus can you host these dasm's here? Would be very useful as a team effort/project. Not to mention help me debug ;D

    I have no problem hosting stuff, I'm just concerned about legalities...

    Think there will be any problems hosting disassemblies of GM code? I'm not big into the legal stuff.

    dont know the legalities but see a few fully documented memcal dasms have been posted at ECMguy's page for a long time:

    Re: 68332 disassembler

    Hmm.. i won't host IDA files, but I might host some html disassemblies...

    I just don't want big brother GM coming down on me.

    On the subject of copyrights..
    In 1992 Sega enterprises, LTD v. Accolade, Inc
    977F2d 1510 9th Circuit Court ruled:

    "we conclude that where disassembly is the only way to gain access to the ideas and functional elements embodied in a copyrighted computer program and where there is a legitimate reason for seeking such access, disassembly is a fair use of the copyrighted work, as a matter of law"

    Accolade was reverse engineering games to create their own games for Genesis game console. They won the case and precedent was set for further cases.

    It's been very quiet around here lately.

    Everybody must be busy disassembling code ;D

    Yamaichi makes a low profile ZIF socket, worked great on my PCM. Look at

    http://diy-efi.org/gmecm/ecm_info/obd2/

    for a pointer. I got 10 from future active for about $3 each.

    Re: 68332 disassembler

    so part # IC179-44600-50** ???

    i'm going to be in the US soon so might pick some up then. I notice 10 insertions/extractions is the spec... guess i better buy a few then ;D

    The 2 part numbers you need are:
    IC179-44600-500 and
    IC179-44600-500-COVER

    Hi Chris
    Did you ever finish this disassembler?
    I am learning how to disassemble a CPU32 DME and am very interested in what you guys did.
    Cheers

    Hi there..
    I realized this was a very old post but also thought that 7 years later maybe you perfected a CPU32 disassembler...

    Any chance you could give me advice how to get a good disassembly with IDA please?

    When I load the BIN file in IDA I choose Motorola 68330 as processor and that is about as far as I know I am doing things right.

    Is there somewhere a nice explanation on how to recognize the code sections etc etc...?

    Thanks for your time

    the reset vector is at 0x04 for the 332, press C or P at the vector there and away you go.

    RAM is 0xFFFF0000 to 0xFFFFFFFF

    Howdy, I know this is an old thread, but I wanted to pop in and see if anyone had some suggestions for me.

    I've got a built 60 degree V6(3400) being run a grand am PCM, which uses this same processor, and I would like to make several changes to more optimally run the engine. My current engine is capable of 7500+ RPM, and I would like to be able to take it there, but My PCM maxes out currently at 6400 RPM, my plan was to slightly lower the resolution of the tables so they occupy the same space on the prom, but can cover more RPM.

    I've got the file opened in IDA, and I have been doing a little bit of digging around, and have found a couple of things here and there, but I haven't been able to figure out how to modify things like the table headers yet.

    Long term, I'd like to get the engine running a coil per cylinder setup instead of the stock DIS setup, which I think might be as simple as using the code that was used to run the LX5 DOHC engine with either a crank trigger swap or a bit of crank trigger code swapping.

    I don't have a coding background, so I'm doing alot of fast learning, if you have any suggestions, I'm all ears.

    Thanks-

    Eric
    yep, I'm that guy.
