    New Guy...

    Hi, I am Juan New Guy. I just completed a 350 tbi to 454 vortec swap in my 1994 full-size Blazer and since my hands were already dirty, I went ahead and replaced the 4l60e with a 4l80e and since I had a 14 bolt SF I went ahead and replaced the 10 bolt rear end. Now for the black box....They told me that you might be able to help me fine tune it. Thanks!-Juan Mendoza.

    The best way for us know what is happening with the current tune is share a TunerPro RT data log (.xdl file) with us.

    Well, I'm embarrassed

    I did not catch on that you are using a "Black Box" Vortec PCM. TunerPro RT does not support the "Black Box" Vortec PCM.

    I do not have any suggestions for a tuner kit for the "Black Box" Vortec PCM.

    Last year, I helped with a 1999 Vortec 454 conversion into a 1994 K1500 / 4L60E. We used the original 1994 OBD1 TBI computer (with the MPFI upgrade) using a custom chip I programmed. The original TBI wiring harness was modified to work with the 1999 Vortec 454 engine.

    JEt DST and a used Tunercat OBD2 will tune the 96-97 Vortecs.

    or upgrade to the 0411PCM(repin) and you can use those 2 suites as well as EFILive/HPTuners.

    Those options (limited / expensive) for the 96 - 97 Vortec's were why I upgraded / modified the ODB1 TBI computer to Multi-Point Fuel Injection (MPFI) to operate the 8 injectors of the Vortec 454 like the older TPI computer operates 8 fuel injectors.

    I am thinking of the 0411 up grade. Right now I am looking for another 1997 vortec wiring harness so that I can take my time re-pinning the 0411.

    There is a gentleman who has already put together the pinout swaps, the 1996/97/98's are all different.

    His callsign is Lextech, he's on many forums including this one. His chart makes teh swap very easy.

    Go to the memberlist, and send him a PM with your email, and he will send you the swap charts for your particular truck. He can also supply you with a411 already calibrated with a starter tune.
    Here is his Gearheads link.
