    Ah - Excel 2007 .... still using the ol' Excel 2000 (had issues with Office 2003 on my ol' dog laptop).

    Anyway, I updated the file a little (hopefully easier to edit for everyone). I'll also post it as a PDF incase someone wants to look at it and doesn't have Excel.

    Anyone know what the E37 uses? Guessing 58X and 4X for the crank and cam.

    Good idea (.xls and .pdf)

    For LS1B(512) it says "97-03 Corvette" and "98-02 Camaro"...
    shouldn't those say: "99-03 Corvette" and "99-02 Camaro"...?

    Hey Guys

    Sorry to hear our versions of Excel don’t like each other. I attached chart revision 1 – using the “save as” Excel 97-03 feature in Excel. Let me know if this is compatible with your versions of Excel. Hopefully it is – will save a lot of headaches.

    Joecar – you are correct LS1-B should say 99-02 Camaro (my typo from revision 1) and 99-03 Corvette (transition typo).

    Darren – it’s unfortunate that you had to make another chart. There are a few errors from transferring the information from revision 1. I had corrected the original misinterpretation of the E40 PCM … it got put back the original (incorrect) way.

    • there is no “early” or “late” E40 – they’re the same PCM – some 2005 applications were Gen III, some were Gen IV
    • there is an “early” and “late” LS2 (Gen III and Gen IV)
    • the 05-06 SSR LS2 in an early LS2 – 24x CKP and 1x CMP
    • the engine codes that help to identify early LS2 engines (5MC, 6MC, YTA, ZJA, ZJB) did not get transferred into the current chart notes column

    Regards,
    Taz

    Taz,

    Sorry for missing those things. I tried to open your repost, but it still shows the funky formating.

    Anyway, here's the latest updates.

    Thanks,

    Hello Darren,

    Sorry to hear that again, the file didn’t open in a workable fashion for you. What specific version of Excel do you have, other than Office 2000 – does it indicate 3.0 or 4.0 or any further distinction ? I should be able to save the file using a newer version of Excel, such that an older version of Excel is able to use it – just need to find the correct “save as” parameter.

    The chart looks good – excellent updates. Couple of minor revisions:

    • Vortec black box PCM is 512Kb (more of a reminder to those considering a swap to an LS1-B style PCM)


    In the E40 applications column – should read:
    • 05-06 Grand Prix GXP
    • 06 Monte Carlo SS
    • 06 Impala SS


    As stated in previous posts, the Gen IV (E38 / E67) and “Inline engine” (P10 / P11 / P12) information remains sparse. Hopefully forum members with experience in these areas will take a moment to forward some additional information. A member who tunes the P10 / P11 / P12 type PCM had made comment in this thread about a week ago – hopefully he’ll find the time to forward some much need information based on his expertise.


    Regards,
    Taz

    Taz, corrections made.

    Here is the updated files.

    I agree, that it would be nice to get some more info on the other PCM's out there. joecar, maybe we could put a specific link in the other forums to ask for their input in case they don't frequent this one?

    Hello Wolfie,

    Pleased you found the collection of information useful. Thank you for contributing to the database. Your Express is DBW (Drive By Wire) correct ?

    PCM service # 12602081 is a common ’06-’07 Gen III PCM. OS 12613248 is common to ’07 trucks / vans with a Gen III V8 and DBW.

    Darren (turbo_bu) is the “keeper of the crypt” on this project – our versions of Excel don’t play well together. When he sees this post, I trust he will update the file – adding your input.

    Thanks again ……


    Regards,
    Taz
