    I have a few left from past projects - they have all been converted to 28-pin DIP
    sockets so that I can easily swap between an Ostrich emulator and the final EPROM.
    I'd be willing to let one go.

    91 Cutlass with a 3300 V6 looks like it might need the $AE XDF

    Perhaps give this one a try?

    2-bar MAP scalar and offset

    I recently ordered a supercharger for my old Pontiac 455, and will be converting to Bubba's
    Beta Boost OS. I ordered up an OEM GM 2-bar MAP sensor, p/n 19418810, which should be
    here this weekend....

    That is definitely an easy swap. The knock sensor in the engine block is the only critical difference you
    will want to handle. The '96 PCM is expecting a knock sensor with a resistance of...

    No need at all to touch the coil or ignition module. Swapping a '96 LT1 to the 94-5 8051 PCM is nearly
    a plug and play affair. I've done more than I can count over the years, mostly in the days...

    Conducted multiple reads and writes on a P59 PCM using both an AVT838 and AVT852. No errors to report
    using either one. The AVT838 seems to run roughly half as quickly as the AVT852, but in the...

    DBC/6.0/4L80E BINs for 7603 OS

  11. 94-95 PCMs

    I believe that the 16197427 was only found in 94-5 trucks, SUVs and vans with a V8. The other PCM found
    in those same years/vehicles was the 16196395. I haven't personally used one, by my...
  12. TBI for the traditional Pontiac

    As others had said, the 16197427 is a great choice for TBI applications, and can be found in
    many 94-5 TBI trucks. I had planned to go this route on the 455 in my 70 Bonneville for a
    long time,...

    One of my favorite expressions when diagnosing problems like these is "It always stinks worst

    This thread brings back some good memories for me of my 91 Olds CC. I removed its
    tired 305 and swapped in an L29 style Vortec 454.
