    Stock files (.bin, .cal, .tun) for LS1a PCM 16238212

    I'm hoping someone can help me with a manual transmission file (.bin,.cal, .tun) for a LS1a 16238212 computer.

    The attached files are from the 1998 Pontiac Firebird Formula 5.7 liter / 4L60E Auto PCM I'm working with.

    Thanks,
    dave w

    Can you change the OS? If so there is a manual on Tune File Depot... 1998 Trans-Am Coupe Manual 5.7 Litre (LS1) 19980100 (PCM) LS1A 468 K

    1990 Chevy Suburban 5.7L Auto ECM 1227747 $42!
    1998 Chevy Silverado 5.7L Vortec 0411 Swap to RoadRunner!

    The *.tun file in post #1 is 19980100 ... so your suggestion should work.

    Interesting. To bad these PCM are hard to find and extremely expensive if / when you can find one.
