    Thanks! Did you get the SECURITY key figured out?
    As for me, I utilize the LS droid & Tunerpro. This is the first Experience I will have with PCM/ECM at this level. I believe I have all the needed .bin's & the matching .xdf, however I have yet to change anything over. Just gathering info and such until I feel comfortable to do what I have planned. -No vats, keep hug-a-tree features, manual, switch VIN correspondingly, and utilize E-fan controls.
    My main goal is the have the 1994 S-10 work truck with a to stockish spec of a 2002 Chevy PCM. I want to be able to hook up my Autel and when it decoded the vehical, it will do so as a 94 S-10 w/ 5.7. Plus I can use the scan tool to be able to bleed my ABS! Yeap, going to remove the ABS of the 94 stock to the 02 version also. I am in the process of converting the dash & heater box to a 02 S-10 currently. Lot of spot welds!! When labor part is said and done it will be a 'plug & play!'

    No, I have not.

    The file posted above is the .bin file format of the file on gmtruckcentral.

    Thanks Dave. Good read. I need to figure out how(pin) the wiring of a 96 clutch switch to the 411. I looked on my Identafix and notice the same clutch switch is use in 02 trucks. Just gotta follow the wires on the diagrams I guess.

    Hello! I have been unsuccessful in the attempts of seeping the PCM. You mentioned the Mexican 5 speed. Is it a .bin file?

    What to do?? The (2002 Express Van) 411, OS 2156 PCM states it is a 4L80E, yet I would like to change it to a manual NV3500. The engine is a L31. I am utilizing TunerPro & OBDLink LX.
    I have a .ctz file for the Mexican L31 & manual transmission, yet it seems to be no help since it is not in .bin format.
    So, what can I do? Can the file be converted?

    The attached file is modified. The origins of the attached .bin are unknown.

    Use at your own risk.

    There is an all stock 4.8 manual bin on here that's 2156, you could segment swap it over to your original bin. Is your express van bin stock?

    I could do the seg swap for you if you like and post the bin here

    I seg swapped a bin for you. Both bin files show all stock in universal Patcher, I also deleted VATS.
    I have included all 3 bin files, the two original and the modded one along with a log file of what was changed in the attached zip.
