    Default Used 950 help getting started

    I just bought a used MPFI 950 with a distrubutor I think I have everything. Harness seams to plug into all sensors I need to weld in bungs for oxygen sensors and may need a MSG coil and spark box? Is there anyone who has a list of what comes with? Do I need to send anything to Holly for updates? Its for a crate ZZ4 in a hot rod with auto trans.
    Excited to do change over only know carburation and everyone says don't change to EFI so of course I will...........Thanks Jim

    Hi, O2 bung Sales # is 534-49. To inquire instructions go to http://www.holley.com/TechService/Instructions.asp Type in 91103201 and then submit. This will bring up the instructions for a Commander MPFI kit. Instructions will go over the parts.
    The last software version is 3.07. Last firm ware version is 3.6. If you have earlier software firmware. you will need to call Holley Tech service @ 1-866-464-6553 option 8. We charge $40.00 for upgrade if needed.

    Sincerely
