[Gmecm] Torque converter clutch on 1226869

[David Allen]

  Zaphod, the .bin started out as FTX 9349 which is an 85 Fiero 2.8
automatic. I have selected "2-bar MAP" in the ECM switch table and left
"transmission type" unchecked since "X = manual" Then the spark and fuel
tables have also been tuned somewhat.
  Another thing I can't make work no matter what I place in the .bin is the
wastegate bypass control.  I am wondering if I need to start out with a
different .bin but there aren't many out there for this ECM.
  Thanks,
David
