    GM swap and E-prom information

    I swapped a v8 5.7 TBI into a 1995 GMC truck. I have the 16197427 computer but the Prom number I need is BPUX # 16221008. The problem is I can not find any to replace with my V6 prom. It is a 5.7 M30 trans, GU6 rear end and considerd a C1 Platform. The chip BJYX was superseded to the BPUX. What is the best way to find one of these, been online and at the Junk yards none match. Any help would be appreciated. Thanks

    Might consider BJYL as well. Most of the 94-95 5.7 4l60e trucks use that memcal.

    I can find a BJYK that is a GU6 (3.08) rear end code or a BJYL that is a GT4 (3.73) Which one will work best or does it matter. My truck has a GU6 (3.42) rear end
    Thanks for everyone's Help

    The ratio doesn't matter. The ratio/tire size is calculated in the Drac/VSSB (little white box) before imputed into the PCM.

    Thanks Dave ended up with a BJYK. Truck runs good but I have the EGR deleted causing a back fire when the computer adv the timing. I saw a post a while back somewhere that you use a ALDL cable, TunerPro R and the Moates burner2. Would you still recommend these to make changes in the bin files or would you recommend others like ostridge 2 or the APU1 Set up.
    Thanks

    The two most popular tuning setups are:

    1.
    ALDL Cable
    TunerPro RT
    Moates Burn2
    G1 Adapter Board http://www.moates.net/g1-memory-adap...-etc-p-32.html
    27SF512 Chip http://www.moates.net/c2-sst-27sf512-chip-p-39.html
    ZIF Socket http://www.moates.net/s4-aries-28pin....html?cPath=26 - Optional
    HDR1 http://www.moates.net/hdr1-memcal-he....html?cPath=64 - Optional

    OR
    2.
    ALDL Cable
    TunerPro RT
    G1 Adapter Board http://www.moates.net/g1-memory-adap...-etc-p-32.html
    Ostrich 2.0 http://www.moates.net/ostrich-20-the....html?cPath=64

    The Ostrich 2.0 has a good resale value, if you want to recoup some of the tuning expenses after the tuning is complete.

    Thanks Dave, I understand how the burner 2 works. I have a question on the ostrich 2.0 I looked everywhere on moates ostricjh 2.0 and internet and cant find what to do after you make changes on the fly. Do i have to leave it connected or does it burn chips too?

    Basically the Ostrich 2.0 replaces the chip. The Ostrich 2.0 is programmed with TunerPro RT using a USB cable.

    Thanks Dave, I thought that's how it may work. One more question. If I use the ostrich 2.0 and get my truck tuned the way I want it can I save that to a bin file and hook up the Burner 2 and make a chip from that so I can put the chip in my truck so I can install the ostrich 2.0 on another vehicle an do the same thing?

    Yes, the tune from the Ostrich 2.0 can be downloaded and burned into a chip. There are several members here at gearhead-efi with chip burning equipment that would be willing to help you with converting the Ostrich 2.0 tune into a chip that can be installed into the G1 adapter board.

    Thanks, I orederd the ALDL cable and downloaded the tuner pro rt. So it sounds like the ostrich 2.0 will make life easier and a burner 2. Too bad I didn't get into these sooner. I can do the BMW coding and flash and swap computers. After this is done maybe I can sell some chips. After this project I guess I'm diving into LS computers. I have a 71 FJ40 Land Cruiser with a LS in it. Just about done with the wiring. Will have to get a bunch of stuff deleted and re done on that computer, to bad none of this will work on those. Thanks again Dave for all your help.
