    400D Look up AFR when in closed loop Set
    400F Allow knock prevention Set
    400F Allow knock retard Set
    4136 DRP threshold to transition from crank to run 08
    4137 DRP threshold to transition from crank to run 42
    413C Main SA bias 00
    442F Use vacuum/RPM for MAT SA correction table Set
    5B00 Error 15, low cool temp Set
    5B00 Error 13, O2 sensor error Set
    5B01 Error 23, MAT low Set
    5B03 Error 45, O2 rich Set
    5B03 Error 44, O2 lean Set
    5B03 Error 43, ESC failure Set
    5B03 Error 42, EST failure Set
    5B04 Error 54, fuel pump relay failure Set
    5B04 Error 51, EPROM checksum fail Set

    Those are the parameters I set and it finally it runs !
    Maybe just the Main SA bias or Knock prevention let it run, but dealing with a eprom programmer and
    not a emulator. Tax season hopefuly get one.
    Dang this setup is dam good. Just crank to run is now lean. But I can work with that now that it actually
    runs.

    Running the 5.7l injectors so its dam close. I see the wideband and with feed back with a NB it should be
    spot on. Going to try and mess with the Fail safe speed density if maf fails.
    Setup is a 65 c10 with a 93 van 5.0l, harness, 2002-2003 Astro 4l60e, heavly ported 187 heads by me, ported tbi intake, excessively done TBI, long tube headers, single pattern 214d/444 lift cam.
    Not a screaming RaceSaver 305 but when its free I can't complain. Hope to be a great reliable peppy engine.

    Thanks for the help guys!!!!
